<h3>DbRep</h3>
<ul>
<br>
The purpose of this module is browsing and managing the content of DbLog-databases. The searchresults can be evaluated concerning to various aggregations and the appropriate
Readings will be filled. The data selection will been done by declaration of device, reading and the time settings of selection-begin and selection-end. <br><br>
Almost all database operations are implemented nonblocking. If there are exceptions it will be suggested to.
Optional the execution time of SQL-statements in background can also be determined and provided as reading.
(refer to <a href="#DbRepattr">attributes</a>). <br>
All existing readings will be deleted when a new operation starts. By attribute "readingPreventFromDel" a comma separated list of readings which are should prevent
from deletion can be provided. <br><br>
Currently the following functions are provided: <br><br>
<ul><ul>
<li> Selection of all datasets within adjustable time limits. </li>
<li> Exposure of datasets of a Device/Reading-combination within adjustable time limits. </li>
<li> Selection of datasets by usage of dynamically calclated time limits at execution time. </li>
<li> Highlighting doublets when select and display datasets (fetchrows) </li>
<li> Calculation of quantity of datasets of a Device/Reading-combination within adjustable time limits and several aggregations. </li>
<li> The calculation of summary-, difference-, maximum-, minimum- and averageValues of numeric readings within adjustable time limits and several aggregations. </li>
<li> write back results of summary-, difference-, maximum-, minimum- and average calculation into the database </li>
<li> The deletion of datasets. The containment of deletion can be done by Device and/or Reading as well as fix or dynamically calculated time limits at execution time. </li>
<li> export of datasets to file (CSV-format). </li>
<li> import of datasets from file (CSV-Format). </li>
<li> rename of device/readings in datasets </li>
<li> change of reading values in the database (changeValue) </li>
<li> automatic rename of device names in datasets and other DbRep-definitions after FHEM "rename" command (see <a href="#DbRepAutoRename">DbRep-Agent</a>) </li>
<li> Execution of arbitrary user specific SQL-commands (non-blocking) </li>
<li> Execution of arbitrary user specific SQL-commands (blocking) for usage in user own code (dbValue) </li>
<li> creation of backups of the database in running state non-blocking (MySQL, SQLite) </li>
<li> transfer dumpfiles to a FTP server after backup incl. version control</li>
<li> restore of SQLite- and MySQL-Dumps non-blocking </li>
<li> optimize the connected database (optimizeTables, vacuum) </li>
<li> report of existing database processes (MySQL) </li>
<li> purge content of current-table </li>
<li> fill up the current-table with a (tunable) extract of the history-table</li>
<li> delete consecutive datasets with different timestamp but same values (clearing up consecutive doublets) </li>
<li> Repair of a corrupted SQLite database ("database disk image is malformed") </li>
<li> transmission of datasets from source database into another (Standby) database (syncStandby) </li>
<li> reduce the amount of datasets in database (reduceLog) </li>
<li> delete of duplicate records (delDoublets) </li>
</ul></ul>
<br>
To activate the function <b>Autorename</b> the attribute "role" has to be assigned to a defined DbRep-device. The standard role after DbRep definition is "Client".
Please read more in section <a href="#DbRepAutoRename">DbRep-Agent</a> about autorename function. <br><br>
DbRep provides a <b>UserExit</b> function. With this interface the user can execute own program code dependent from free
definable Reading/Value-combinations (Regex). The interface works without respectively independent from event
generation.
Further informations you can find as described at <a href="#DbRepattr">attribute</a> "userExitFn".
<br><br>
Once a DbRep-Device is defined, the function <b>DbReadingsVal</b> is provided.
With this function you can, similar to the well known ReadingsVal, get a reading value from database.
The function execution is carried out blocking.
The command syntax is: <br><br>
<ul>
<code>DbReadingsVal("&lt;name&gt;","&lt;device:reading&gt;","&lt;timestamp&gt;","&lt;default&gt;") </code> <br><br>
<b>Examples: </b><br>
$ret = DbReadingsVal("Rep.LogDB1","MyWetter:temperature","2018-01-13 08:00:00",""); <br>
attr &lt;name&gt; userReadings oldtemp {DbReadingsVal("Rep.LogDB1","MyWetter:temperature","2018-04-13 08:00:00","")}
<br><br>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>&lt;name&gt;</b> </td><td>: name of the DbRep-Device to request </td></tr>
<tr><td> <b>&lt;device:reading&gt;</b> </td><td>: device:reading whose value is to deliver </td></tr>
<tr><td> <b>&lt;timestamp&gt;</b> </td><td>: timestamp of reading whose value is to deliver (*) in the form "YYYY-MM-DD hh:mm:ss" </td></tr>
<tr><td> <b>&lt;default&gt;</b> </td><td>: default value if no reading value can be retrieved </td></tr>
</table>
</ul>
<br>
(*) If no value can be retrieved at the &lt;timestamp&gt; exactly requested, the chronological most convenient reading
value is delivered back.

<a href="https://forum.fhem.de/index.php/topic,53584.msg452567.html#msg452567">Modul 93_DbRep - Reporting and Management of database content (DbLog)</a>.<br><br>
<br>
</ul>
<b>Preparations </b> <br><br>
<ul>
The module requires the usage of a DbLog instance and the credentials of the database definition will be used. <br>
Only the content of table "history" will be included if isn't other is explained. <br><br>
Overview which other Perl-modules DbRep is using: <br><br>
Net::FTP (only if FTP-Transfer after database dump is used) <br>
Net::FTPSSL (only if FTP-Transfer with encoding after database dump is used) <br>
POSIX <br>
Time::HiRes <br>
Time::Local <br>
Scalar::Util <br>
DBI <br>
Color (FHEM-module) <br>
IO::Compress::Gzip <br>
IO::Uncompress::Gunzip <br>
Blocking (FHEM-module) <br><br>
Due to performance reason the following index should be created in addition: <br>
<code>
CREATE INDEX Report_Idx ON `history` (TIMESTAMP, READING) USING BTREE;
</code>
</ul>
<br>
<a name="DbRepdefine"></a>
<b>Definition</b>
<br>
<ul>
<code>
define &lt;name&gt; DbRep &lt;name of DbLog-instance&gt;
</code>
<br><br>
(&lt;name of DbLog-instance&gt; - name of the database instance which is wanted to analyze needs to be inserted)
</ul>
<br><br>
<a name="DbRepset"></a>
<b>Set </b>
<ul>
Currently following set-commands are included. They are used to trigger the evaluations and define the evaluation option option itself.
The criteria of searching database content and determine aggregation is carried out by setting several <a href="#DbRepattr">attributes</a>.
<br><br>
<ul><ul>
<li><b> averageValue [display | writeToDB]</b>
- calculates the average value of database column "VALUE" between period given by
timestamp-<a href="#DbRepattr">attributes</a> which are set.
The reading to evaluate must be specified by attribute "reading". <br>
By attribute "averageCalcForm" the calculation variant for average determination will be configured.
Is no or the option "display" specified, the results are only displayed. Using
option "writeToDB" the calculated results are stored in the database with a new reading
name. <br>
The new readingname is built of a prefix and the original reading name,
in which the original reading name can be replaced by the value of attribute "readingNameMap".
The prefix is made up of the creation function and the aggregation. <br>
The timestamp of the new stored readings is deviated from aggregation period,
unless no unique point of time of the result can be determined.
The field "EVENT" will be filled with "calculated".<br><br>
<ul>
<b>Example of building a new reading name from the original reading "totalpac":</b> <br>
avgam_day_totalpac <br>
# &lt;creation function&gt;_&lt;aggregation&gt;_&lt;original reading&gt; <br>
</ul>
<br>
Summarized the relevant attributes to control this function are: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>averageCalcForm</b> </td><td>: choose the calculation variant for average determination </td></tr>
<tr><td> <b>device</b> </td><td>: include or exclude &lt;device&gt; from selection </td></tr>
<tr><td> <b>reading</b> </td><td>: include or exclude &lt;reading&gt; from selection </td></tr>
<tr><td> <b>time.*</b> </td><td>: a number of attributes to limit selection by time </td></tr>
<tr><td style="vertical-align:top"> <b>valueFilter</b> <td>: an additional REGEXP to control the record selection. The REGEXP is applied to the database field 'VALUE'. </td></tr>
</table>
</ul>
<br>
<br>
</li><br>
<li><b> cancelDump </b> - stops a running database dump. </li> <br>
<li><b> changeValue </b> - changes the saved value of readings.
If the selection is limited to particular device/reading-combinations by
<a href="#DbRepattr">attribute</a> "device" respectively "reading", it is considered as well
as possibly defined time limits by time attributes (time.*). <br>
If no limits are set, the whole database is scanned and the specified value will be
changed. <br><br>
<ul>
<b>Syntax: </b> <br>
set &lt;name&gt; changeValue "&lt;old string&gt;","&lt;new string&gt;" <br><br>
The strings have to be quoted and separated by comma.
A "string" can be: <br>
<table>
<colgroup> <col width=15%> <col width=85%> </colgroup>
<tr><td style="vertical-align:top"><b>&lt;old string&gt; :</b> <td><li>a simple string with/without spaces, e.g. "OL 12" </li>
<li>a string with usage of SQL-wildcard, e.g. "%OL%" </li> </td></tr>
<tr><td style="vertical-align:top"><b>&lt;new string&gt; :</b> <td><li>a simple string with/without spaces, e.g. "12 kWh" </li>
<li>Perl code embedded in "{}" with quotes, e.g. "{($VALUE,$UNIT) = split(" ",$VALUE)}".
The perl expression the variables $VALUE and $UNIT are committed to.
The variables are changable within the perl code. The returned value
of VALUE and UNIT are saved into the database field VALUE respectively
UNIT of the dataset. </li></td></tr>
</table>
<br>
<b>Examples: </b> <br>
set &lt;name&gt; changeValue "OL","12 OL" <br>
# the old field value "OL" is changed to "12 OL". <br><br>
set &lt;name&gt; changeValue "%OL%","12 OL" <br>
# contains the field VALUE the substring "OL", it is changed to "12 OL". <br><br>
set &lt;name&gt; changeValue "12 kWh","{($VALUE,$UNIT) = split(" ",$VALUE)}" <br>
# the old field value "12 kWh" is splitted to VALUE=12 and UNIT=kWh and saved into the database fields <br><br>
set &lt;name&gt; changeValue "24%","{$VALUE = (split(" ",$VALUE))[0]}" <br>
# if the old field value begins with "24", it is splitted and VALUE=24 is saved (e.g. "24 kWh")
<br><br>
Summarized the relevant attributes to control function changeValue are: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>device</b> </td><td>: include or exclude &lt;device&gt; from selection </td></tr>
<tr><td> <b>reading</b> </td><td>: include or exclude &lt;reading&gt; from selection </td></tr>
<tr><td> <b>time.*</b> </td><td>: a number of attributes to limit selection by time </td></tr>
<tr><td> <b>executeBeforeProc</b> </td><td>: execute a FHEM command (or perl-routine) before start of changeValue </td></tr>

</table>
</ul>
<br>
<br>
<b>Note:</b> <br>
Even though the function itself is designed non-blocking, make sure the assigned DbLog-device
is operating in asynchronous mode to avoid FHEMWEB from blocking. <br><br>
</li> <br>
</ul>
<li><b> countEntries [history|current] </b> - provides the number of table entries (default: history) between time period set
by time.* -<a href="#DbRepattr">attributes</a> if set.
If time.* attributes not set, all entries of the table will be count.
The <a href="#DbRepattr">attributes</a> "device" and "reading" can be used to
limit the evaluation. <br>
By default the summary of all counted datasets, labeled by "ALLREADINGS", will be created.
If the attribute "countEntriesDetail" is set, the number of every reading
is reported additionally. <br><br>
The relevant attributes for this function are: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>

<tr><td> <b>countEntriesDetail</b> </td><td>: detailed report the count of datasets (per reading) </td></tr>
<tr><td> <b>device</b> </td><td>: include or exclude &lt;device&gt; from selection </td></tr>
<tr><td> <b>reading</b> </td><td>: include or exclude &lt;reading&gt; from selection </td></tr>
<tr><td> <b>time.*</b> </td><td>: a number of attributes to limit selection by time </td></tr>
<tr><td style="vertical-align:top"> <b>valueFilter</b> <td>: an additional REGEXP to control the record selection. The REGEXP is applied to the database field 'VALUE'. </td></tr>
</table>
</ul>
<br>
</li> <br>
<li><b> delDoublets [adviceDelete | delete]</b> - show respectively delete duplicate/multiple datasets.
Therefore the fields TIMESTAMP, DEVICE, READING and VALUE of records are compared. <br>
The <a href="#DbRepattr">attributes</a> to define the scope of aggregation,time period, device and reading are
considered. If attribute aggregation is not set or set to "no", it will change to the default aggregation
period "day".
<br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>adviceDelete</b> </td><td>: simulates the datasets to delete in database (nothing will be deleted !) </td></tr>
<tr><td> <b>delete</b> </td><td>: deletes the doublets </td></tr>
</table>
</ul>
<br>
Due to security reasons the attribute <a href="#DbRepattr">attribute</a> "allowDeletion" needs
to be set for execute the "delete" option. <br>
The amount of datasets to show by commands "delDoublets adviceDelete" is initially limited
(default: 1000) and can be adjusted by <a href="#DbRepattr">attribute</a> "limit".
The adjustment of "limit" has no impact to the "delDoublets delete" function, but affects
<b>ONLY</b> the display of the data. <br>
Before and after this "delDoublets" it is possible to execute a FHEM command or Perl script
(please see <a href="#DbRepattr">attributes</a> "executeBeforeProc", "executeAfterProc").
<br><br>
<ul>
<b>Example:</b> <br><br>
Output of records to delete included their amount by "delDoublets adviceDelete": <br><br>

2018-11-07_14-16-37__Dum.Energy__T 264.0_|_2 <br>
<br>
In the created readings after "_|_" the amount of the appropriate records to delete
is shown. The records are deleted by command "delDoublets delete".

is operating in asynchronous mode to avoid FHEMWEB from blocking. <br><br>
</li> <br>
</ul>
<li><b> diffValue [display | writeToDB]</b>
- calculates the difference of database column "VALUE" between period given by
<a href="#DbRepattr">attributes</a> "timestamp_begin", "timestamp_end" or "timeDiffToNow / timeOlderThan".
The reading to evaluate must be defined using attribute "reading".
This function is mostly reasonable if readingvalues are increasing permanently and don't write value-differences to the database.
The difference will be generated from the first available dataset (VALUE-Field) to the last available dataset between the
specified time linits/aggregation, in which a balanced difference value of the previous aggregation period will be transfered to the
following aggregation period in case this period contains a value. <br>
A possible counter overrun (restart with value "0") will be considered (compare <a href="#DbRepattr">attribute</a> "diffAccept"). <br><br>
If only one dataset will be found within the evalution period, the difference can be calculated only in combination with the balanced
difference of the previous aggregation period. In this case a logical inaccuracy according the assignment of the difference to the particular aggregation period
can be possible. Hence in warning in "state" will be placed and the reading "less_data_in_period" with a list of periods
with only one dataset found in it will be created.
<br><br>
<ul>
<b>Note: </b><br>
Within the evaluation respectively aggregation period (day, week, month, etc.) you should make available at least one dataset
at the beginning and one dataset at the end of each aggregation period to take the difference calculation as much as possible.
<br>
<br>
</ul>
Is no or the option "display" specified, the results are only displayed. Using
option "writeToDB" the calculation results are stored in the database with a new reading
name. <br>
The new readingname is built of a prefix and the original reading name,
in which the original reading name can be replaced by the value of attribute "readingNameMap".
The prefix is made up of the creation function and the aggregation. <br>
The timestamp of the new stored readings is deviated from aggregation period,
unless no unique point of time of the result can be determined.
The field "EVENT" will be filled with "calculated".<br><br>
<ul>
<b>Example of building a new reading name from the original reading "totalpac":</b> <br>

<li><b> dumpMySQL [clientSide | serverSide]</b>
- creates a dump of the connected MySQL database. <br>
Depending from selected option the dump will be created on Client- or on Server-Side. <br>
The variants differs each other concerning the executing system, the creating location, the usage of
attributes, the function result and the needed hardware ressources. <br>
The option "clientSide" e.g. needs more powerful FHEM-Server hardware, but saves all available
tables inclusive possibly created views. <br>
With attribute "dumpCompress" a compression of dump file after creation can be switched on.
<br><br>
<ul>
<b><u>Option clientSide</u></b> <br>
The dump will be created by client (FHEM-Server) and will be saved in FHEM log-directory by
default.
The target directory can be set by <a href="#DbRepattr">attribute</a> "dumpDirLocal" and has to be
writable by the FHEM process. <br>
Before executing the dump a table optimization can be processed optionally (see attribute
"optimizeTablesBeforeDump") as well as a FHEM-command (attribute "executeBeforeProc").
After the dump a FHEM-command can be executed as well (see attribute "executeAfterProc"). <br><br>
<b>Note: <br>
To avoid FHEM from blocking, you have to operate DbLog in asynchronous mode if the table
optimization want to be used ! </b> <br><br>
By the <a href="#DbRepattr">attributes</a> "dumpMemlimit" and "dumpSpeed" the run-time behavior of the function can be
controlled to optimize the performance and demand of ressources. <br><br>
The attributes relevant for function "dumpMySQL clientSide" are: <br><br>
<ul>

</table>
</ul>
<br>
After a successfull finished dump the old dumpfiles are deleted and only the number of files
defined by attribute "dumpFilesKeep" (default: 3) remain in the target directory
"dumpDirLocal". If "dumpFilesKeep = 0" is set, all
dumpfiles (also the current created file), are deleted. This setting can be helpful, if FTP transmission is used
and the created dumps are only keep remain in the FTP destination directory. <br><br>
The <b>naming convention of dump files</b> is: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.sql[.gzip] <br><br>
To rebuild the database from a dump file the command: <br><br>
<ul>
set &lt;name&gt; restoreMySQL &lt;filename&gt; <br><br>
</ul>
can be used. <br><br>
The created dumpfile (uncompressed) can imported on the MySQL-Server by: <br><br>
<ul>
mysql -u &lt;user&gt; -p &lt;dbname&gt; < &lt;filename&gt;.sql <br><br>
</ul>
as well to restore the database from dump file. <br><br><br>
<b><u>Option serverSide</u></b> <br>
The dump will be created on the MySQL-Server and will be saved in its Home-directory
by default. <br>
The whole history-table (not the current-table) will be exported <b>CSV-formatted</b> without
any restrictions. <br>
Before executing the dump a table optimization can be processed optionally (see attribute
"optimizeTablesBeforeDump") as well as a FHEM-command (attribute "executeBeforeProc"). <br><br>
<b>Note: <br>
To avoid FHEM from blocking, you have to operate DbLog in asynchronous mode if the table
optimization want to be used ! </b> <br><br>
After the dump a FHEM-command can be executed as well (see attribute "executeAfterProc"). <br><br>
The attributes relevant for function "dumpMySQL serverSide" are: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> dumpDirRemote </td><td>: destination directory of dump file on remote server </td></tr>
<tr><td> dumpCompress </td><td>: compress of dump files after creation </td></tr>

</table>
</ul>
<br>
The target directory can be set by <a href="#DbRepattr">attribute</a> "dumpDirRemote".
It must be located on the MySQL-Host and has to be writable by the MySQL-server process. <br>
The used database user must have the "FILE"-privilege. <br><br>
<b>Note:</b> <br>
If the internal version management of DbRep should be used and the size of the created dumpfile be
reported, you have to mount the remote MySQL-Server directory "dumpDirRemote" on the client
and publish it to the DbRep-device by fill out the <a href="#DbRepattr">attribute</a>
"dumpDirLocal". <br>
Same is necessary if ftp transfer after dump is to be used (attribute "ftpUse" respectively "ftpUseSSL").
<br><br>
<ul>
<b>Example: </b> <br>
attr &lt;name&gt; dumpDirRemote /volume1/ApplicationBackup/dumps_FHEM/ <br>
attr &lt;name&gt; dumpDirLocal /sds1/backup/dumps_FHEM/ <br>
attr &lt;name&gt; dumpFilesKeep 2 <br><br>
# The dump will be created remote on the MySQL-Server in directory
'/volume1/ApplicationBackup/dumps_FHEM/'. <br>
# The internal version management searches in local mounted directory '/sds1/backup/dumps_FHEM/'
for present dumpfiles and deletes these files except the last two versions. <br>
<br>
</ul>
If the internal version management is used, after a successfull finished dump old dumpfiles will
be deleted and only the number of attribute "dumpFilesKeep" (default: 3) would remain in target
directory "dumpDirLocal" (the mounted "dumpDirRemote").
In that case FHEM needs write permissions to the directory "dumpDirLocal". <br><br>
The <b>naming convention of dump files</b> is: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.csv[.gzip] <br><br>
You can start a restore of table history from serverSide-Backup by command: <br><br>
<ul>
set &lt;name&gt; &lt;restoreMySQL&gt; &lt;filename&gt;.csv[.gzip] <br><br>
</ul>
<br><br>
<b><u>FTP-Transfer after Dump</u></b> <br>
If those possibility is be used, the <a href="#DbRepattr">attribute</a> "ftpUse" or
"ftpUseSSL" has to be set. The latter if encoding for FTP is to be used.
The module also carries the version control of dump files in FTP-destination by attribute
"ftpDumpFilesKeep". <br>
Further <a href="#DbRepattr">attributes</a> are: <br><br>
<ul>

</li><br>
<li><b> dumpSQLite </b> - creates a dump of the connected SQLite database. <br>
This function uses the SQLite Online Backup API and allow to create a consistent backup of the
database during the normal operation.
The dump will be saved in FHEM log-directory by default.
The target directory can be defined by <a href="#DbRepattr">attribute</a> "dumpDirLocal" and
has to be writable by the FHEM process. <br>
Before executing the dump a table optimization can be processed optionally (see attribute

</ul>
<br>
After a successfull finished dump the old dumpfiles are deleted and only the number of attribute
"dumpFilesKeep" (default: 3) remain in the target directory "dumpDirLocal". If "dumpFilesKeep = 0" is set, all
dumpfiles (also the current created file), are deleted. This setting can be helpful, if FTP transmission is used
and the created dumps are only keep remain in the FTP destination directory. <br><br>
The <b>naming convention of dump files</b> is: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.sqlitebkp[.gzip] <br><br>
The database can be restored by command "set &lt;name&gt; restoreSQLite &lt;filename&gt;" <br>
The created dump file can be transfered to a FTP-server. Please see explanations about FTP-
transfer in topic "dumpMySQL". <br><br>
</li><br>
<li><b> eraseReadings </b> - deletes all created readings in the device, except reading "state" and readings, which are
contained in exception list defined by attribute "readingPreventFromDel".
</li><br>
<li><b> exportToFile [&lt;file&gt;] </b>
- exports DB-entries to a file in CSV-format of time period specified by time attributes. <br>
Limitation of selections can be done by <a href="#DbRepattr">attributes</a> device and/or
reading.
The filename can be defined by <a href="#DbRepattr">attribute</a> "expimpfile". <br>
Optionally a file can be specified as a command option (/path/file) and overloads a possibly
defined attribute "expimpfile". The filename may contain wildcards as described
in attribute section of "expimpfile".
<br>
By setting attribute "aggregation" the export of datasets will be splitted into time slices
corresponding to the specified aggregation.
If, for example, "aggregation = month" is set, the data are selected in monthly packets and written
into the exportfile. Thereby the usage of main memory is optimized if very large amount of data
is exported and avoid the "died prematurely" error. <br><br>

<li><b> fetchrows [history|current] </b>
- provides <b>all</b> table entries (default: history)
of time period set by time <a href="#DbRepattr">attributes</a> respectively selection conditions
by attributes "device" and "reading".
An aggregation set will <b>not</b> be considered. <br>
The direction of data selection can be determined by <a href="#DbRepattr">attribute</a>
"fetchRoute". <br><br>
Every reading of result is composed of the dataset timestring , an index, the device name
and the reading name.
The function has the capability to reconize multiple occuring datasets (doublets).
Such doublets are marked by an index > 1. <br>
Doublets can be highlighted in terms of color by setting attribut e"fetchMarkDuplicates". <br><br>
<b>Note:</b> <br>
Highlighted readings are not displayed again after restart or rereadcfg because of they are not
saved in statefile. <br><br>
This attribute is preallocated with some colors, but can be changed by colorpicker-widget: <br><br>
<ul>
<code>
attr &lt;DbRep-Device&gt; widgetOverride fetchMarkDuplicates:colorpicker
</code>
</ul>
<br>
The readings of result are composed like the following sceme: <br><br>
<ul>
<b>Example:</b> <br>

<br>
For compatibility reasons the reducelog command can optionally be completed with supplements "EXCLUDE"
respectively "INCLUDE" to exclude and/or include device/reading combinations from reducelog: <br><br>
<ul>
"reduceLog [average[=day]] [EXCLUDE=device1:reading1,device2:reading2,...] [INCLUDE=device:reading]" <br><br>
</ul>
This declaration is evaluated as Regex and overwrites the attributes "device" and "reading",
which won't be considered in this case. <br><br>
<ul>
<b>Examples: </b><br><br>
attr &lt;name&gt; timeOlderThan = d:200 <br>
set &lt;name&gt; reduceLog <br>
# Records older than 200 days are reduced to the first entry per hour of each device and reading.
<br>
<br>
attr &lt;name&gt; timeDiffToNow = d:200 <br>
set &lt;name&gt; reduceLog average=day <br>
# Records newer than 200 days are reduced to a single average a day of each device and reading.
<br>
<br>
attr &lt;name&gt; timeDiffToNow = d:30 <br>
attr &lt;name&gt; device = TYPE=SONOSPLAYER EXCLUDE=Sonos_Kueche <br>
attr &lt;name&gt; reading = room% EXCLUDE=roomNameAlias <br>
set &lt;name&gt; reduceLog <br>
# Records newer than 30 days which are contain devices from type SONOSPLAYER
(except device "Sonos_Kueche"), the readings beginning with "room" (except "roomNameAlias"),
are reduced to the first entry per hour of each device and reading. <br>
<br>
attr &lt;name&gt; timeDiffToNow = d:10 <br>
attr &lt;name&gt; timeOlderThan = d:5 <br>
attr &lt;name&gt; device = Luftdaten_remote <br>
set &lt;name&gt; reduceLog average <br>
# Records older than 5 and newer than 10 days and contain DEVICE "Luftdaten_remote" are
revised. Numerical values are reduced to the first entry per hour of each device and reading
<br>
<br>
</ul>
<b>Note:</b> <br>
Even though the function itself is non-blocking, you have to set the attached DbLog device into
the asynchronous mode (attr asyncMode = 1) to avoid a blocking situation of FHEM !. <br>
It is strongly recommended to check if the default INDEX 'Search_Idx' exists on the table
'history'! <br><br>
</li> <br>
<li><b> repairSQLite </b> - repairs a corrupted SQLite database. <br>
A corruption is usally existent when the error message "database disk image is malformed"
appears in reading "state" of the connected DbLog-device.
If the command was started, the connected DbLog-device will firstly disconnected from the
database for 10 hours (36000 seconds) automatically (breakup time). After the repair is
finished, the DbLog-device will be connected to the (repaired) database immediately. <br>
As an argument the command can be completed by a differing breakup time (in seconds). <br>
The corrupted database is saved as &lt;database&gt;.corrupt in same directory. <br><br>
<ul>
<b>Example: </b><br>
set &lt;name&gt; repairSQLite <br>
# the database is trying to repair, breakup time is 10 hours <br>
set &lt;name&gt; repairSQLite 600 <br>
# the database is trying to repair, breakup time is 10 minutes
<br><br>
<b>Note:</b> <br>
It can't be guaranteed, that the repair attempt proceed successfully and no data loss will result.
Depending from corruption severity data loss may occur or the repair will fail even though
no error appears during the repair process. Please make sure a valid backup took place ! <br><br>
</li> <br>
</ul>
<li><b> restoreMySQL &lt;File&gt; </b> - restore a database from serverSide- or clientSide-Dump. <br>
The function provides a drop-down-list of files which can be used for restore. <br><br>
<b>Usage of serverSide-Dumps </b> <br>
The content of history-table will be restored from a serverSide-Dump.
Therefore the remote directory "dumpDirRemote" of the MySQL-Server has to be mounted on the
Client and make it usable to the DbRep-device by setting <a href="#DbRepattr">attribute</a>
"dumpDirLocal" to the appropriate value. <br>
All files with extension "csv[.gzip]" and if the filename is beginning with the name of the connected database
(see Internal DATABASE) are listed.
<br><br>
<b>Usage of clientSide-Dumps </b> <br>
All tables and views (if present) are restored.
The directory which contains the dump files has to be set by <a href="#DbRepattr">attribute</a>
"dumpDirLocal" to make it usable by the DbRep device. <br>
All files with extension "sql[.gzip]" and if the filename is beginning with the name of the connected database
(see Internal DATABASE) are listed. <br>
The restore speed depends of the server variable "<b>max_allowed_packet</b>". You can change
this variable in file my.cnf to adapt the speed. Please consider the need of sufficient ressources
(especially RAM).
<br><br>
The database user needs rights for database management, e.g.: <br>
CREATE, ALTER, INDEX, DROP, SHOW VIEW, CREATE VIEW
<br><br>
</li><br>
<li><b> restoreSQLite &lt;File&gt;.sqlitebkp[.gzip] </b> - restores a backup of SQLite database. <br>
The function provides a drop-down-list of files which can be used for restore.
The data stored in the current database are deleted respectively overwritten.
All files with extension "sqlitebkp[.gzip]" and if the filename is beginning with the name of the connected database
will are listed. <br><br>
</li><br>
<li><b> sqlCmd </b> - executes an arbitrary user specific command. <br>
If the command contains a operation to delete data, the <a href="#DbRepattr">attribute</a>
"allowDeletion" has to be set for security reason. <br>
The statement doesn't consider limitations by attributes "device", "reading", "time.*"
respectively "aggregation". <br>
This command also accept the setting of SQL session variables like "SET @open:=NULL,
@closed:=NULL;". <br>
If the <a href="#DbRepattr">attribute</a> "timestamp_begin" respectively "timestamp_end"
is assumed in the statement, it is possible to use placeholder "<b>§timestamp_begin§</b>" respectively
"<b>§timestamp_end§</b>" on suitable place. <br><br>
If you want update a dataset, you have to add "TIMESTAMP=TIMESTAMP" to the update-statement to avoid changing the
original timestamp. <br><br>
<ul>
<b>Examples of SQL-statements: </b> <br><br>
<ul>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= "2017-01-06 00:00:00" group by DEVICE having count(*) > 800 </li>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= "2017-05-06 00:00:00" group by DEVICE </li>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= §timestamp_begin§ group by DEVICE </li>
<li>set &lt;name&gt; sqlCmd select * from history where DEVICE like "Te%t" order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select * from history where `TIMESTAMP` > "2017-05-09 18:03:00" order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select * from current order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select sum(VALUE) as 'Einspeisung am 04.05.2017', count(*) as 'Anzahl' FROM history where `READING` = "Einspeisung_WirkP_Zaehler_Diff" and TIMESTAMP between '2017-05-04' AND '2017-05-05' </li>
<li>set &lt;name&gt; sqlCmd delete from current </li>
<li>set &lt;name&gt; sqlCmd delete from history where TIMESTAMP < "2016-05-06 00:00:00" </li>
<li>set &lt;name&gt; sqlCmd update history set TIMESTAMP=TIMESTAMP,VALUE='Val' WHERE VALUE='TestValue' </li>
<li>set &lt;name&gt; sqlCmd select * from history where DEVICE = "Test" </li>
<li>set &lt;name&gt; sqlCmd insert into history (TIMESTAMP, DEVICE, TYPE, EVENT, READING, VALUE, UNIT) VALUES ('2017-05-09 17:00:14','Test','manuell','manuell','Tes§e','TestValue','°C') </li>
</ul>
<br>
Here you can see an example of a more complex statement (MySQL) with setting SQL session
variables: <br><br>
<ul>
<li>set &lt;name&gt; sqlCmd SET @open:=NULL, @closed:=NULL;
SELECT
TIMESTAMP, VALUE,DEVICE,
@open AS open,
@open := IF(VALUE = 'open', TIMESTAMP, NULL) AS curr_open,
@closed := IF(VALUE = 'closed', TIMESTAMP, NULL) AS closed
FROM history WHERE
DATE(TIMESTAMP) = CURDATE() AND
DEVICE = "HT_Fensterkontakt" AND
READING = "state" AND
(VALUE = "open" OR VALUE = "closed")
ORDER BY TIMESTAMP; </li>
</ul>
<br>
The result of the statement will be shown in <a href="#DbRepReadings">Reading</a> "SqlResult".
The formatting of result can be choosen by <a href="#DbRepattr">attribute</a> "sqlResultFormat", as well as the used
field separator can be determined by <a href="#DbRepattr">attribute</a> "sqlResultFieldSep". <br><br>
The module provides a command history once a sqlCmd command was executed successfully.
To use this option, activate the attribute "sqlCmdHistoryLength" with list lenght you want. <br><br>
For a better overview the relevant attributes for sqlCmd are listed in a table: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>allowDeletion</b> </td><td>: activates capabilty to delete datasets </td></tr>
<tr><td> <b>sqlResultFormat</b> </td><td>: determines presentation style of command result </td></tr>
<tr><td> <b>sqlResultFieldSep</b> </td><td>: choice of a useful field separator for result </td></tr>
<tr><td> <b>sqlCmdHistoryLength</b> </td><td>: activates command history and length </td></tr>
</table>
</ul>
<br>
<br>
<b>Note:</b> <br>
Even though the module works non-blocking regarding to database operations, a huge
sample space (number of rows/readings) could block the browser session respectively
FHEMWEB.
If you are unsure about the result of the statement, you should preventively add a limit to
the statement. <br><br>
</li><br>
</ul>
<li><b> sqlCmdHistory </b> - If history is activated by <a href="#DbRepattr">attribute</a> "sqlCmdHistoryLength", an already
successfully executed sqlCmd-command can be repeated from a drop-down list. <br>
By execution of the last list entry, "__purge_historylist__", the list itself can be deleted. <br>
If the statement contains "," this character is displayed as "&lt;c&gt;" in the history
list due to technical restrictions. <br>
</li><br>
<li><b> sqlSpecial </b> - This function provides a drop-down list with a selection of prepared reportings. <br>
The statements result is depicted in reading "SqlResult".
The result can be formatted by <a href="#DbRepattr">attribute</a> "sqlResultFormat",
a well as the used field separator by <a href="#DbRepattr">attribute</a> "sqlResultFieldSep".
<br><br>
The relevant attributes for this function are: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>sqlResultFormat</b> </td><td>: determines the formatting of the result </td></tr>
<tr><td> <b>sqlResultFieldSep</b> </td><td>: determines the used field separator in statement result </td></tr>

</li><br><br>
<li><b> sumValue [display | writeToDB]</b>
- calculates the summary of database column "VALUE" between period given by
<a href="#DbRepattr">attributes</a> "timestamp_begin", "timestamp_end" or
"timeDiffToNow / timeOlderThan". The reading to evaluate must be defined using attribute
"reading". Using this function is mostly reasonable if value-differences of readings
are written to the database. <br>
Is no or the option "display" specified, the results are only displayed. Using
option "writeToDB" the calculation results are stored in the database with a new reading
name. <br>
The new readingname is built of a prefix and the original reading name,
in which the original reading name can be replaced by the value of attribute "readingNameMap".
The prefix is made up of the creation function and the aggregation. <br>
The timestamp of the new stored readings is deviated from aggregation period,
unless no unique point of time of the result can be determined.
The field "EVENT" will be filled with "calculated".<br><br>
<ul>
<b>Example of building a new reading name from the original reading "totalpac":</b> <br>
sum_day_totalpac <br>
# &lt;creation function&gt;_&lt;aggregation&gt;_&lt;original reading&gt; <br>

<li><b> syncStandby &lt;DbLog-Device Standby&gt; </b>
- datasets of the connected database (source) are transmitted into another database
(Standby-database). <br>
Here the "&lt;DbLog-Device Standby&gt;" is the DbLog-Device what is connected to the
Standby-database. <br><br>
All the datasets which are determined by timestamp-<a href="#limit">attributes</a>
or respectively the attributes "device", "reading" are transmitted. <br>
The datasets are transmitted in time slices accordingly to the adjusted aggregation.
If the attribute "aggregation" has value "no" or "month", the datasets are transmitted
automatically in daily time slices into standby-database.
Source- and Standby-database can be of different types.

<li><b> tableCurrentFillup </b> - the current-table will be filled u with an extract of the history-table.
The <a href="#DbRepattr">attributes</a> for limiting time and device, reading are considered.
Thereby the content of the extract can be affected. In the associated DbLog-device the attribute "DbLogType" should be set to
"SampleFill/History". </li> <br>
<li><b> tableCurrentPurge </b> - deletes the content of current-table. There are no limits, e.g. by attributes "timestamp_begin", "timestamp_end", device, reading
and so on, considered. </li> <br>
<li><b> vacuum </b> - optimize tables in the connected database (SQLite, PostgreSQL). <br>
Before and after an optimization it is possible to execute a FHEM command.
(please see <a href="#DbRepattr">attributes</a> "executeBeforeProc", "executeAfterProc")
<br><br>
<ul>
<b>Note:</b> <br>
Even though the function itself is designed non-blocking, make sure the assigned DbLog-device

</li>
</ul><br>
<br>
</ul></ul>
<b>For all evaluation variants (except sqlCmd,deviceRename,readingRename) applies: </b> <br>
In addition to the needed reading the device can be complemented to restrict the datasets for reporting / function.
If no time limit attribute is set but aggregation is set, the period from the oldest dataset in database to the current
date/time will be used as selection criterion. If the oldest dataset wasn't identified, then '1970-01-01 01:00:00' is used
as start date (see get &lt;name&gt; "minTimestamp" also).
If both time limit attribute and aggregation isn't set, the selection on database is runnung without timestamp criterion.

</ul>
<a name="DbRepget"></a>
<b>Get </b>
<ul>
The get-commands of DbRep provide to retrieve some metadata of the used database instance.
Those are for example adjusted server parameter, server variables, datadasestatus- and table informations. THe available get-functions depending of
the used database type. So for SQLite curently only "get svrinfo" is usable. The functions nativ are delivering a lot of outpit values.
They can be limited by function specific <a href="#DbRepattr">attributes</a>. The filter has to be setup by a comma separated list.
SQL-Wildcard (%) can be used to setup the list arguments.
<br><br>
<b>Note: </b> <br>
After executing a get-funktion in detail view please make a browser refresh to see the results !
<br><br>
<ul><ul>
<li><b> blockinginfo </b> - list the current system wide running background processes (BlockingCalls) together with their informations.
If character string is too long (e.g. arguments) it is reported shortened.
</li>
<br><br>
<li><b> dbstatus </b> - lists global informations about MySQL server status (e.g. informations related to cache, threads, bufferpools, etc. ).
Initially all available informations are reported. Using the <a href="#DbRepattr">attribute</a> "showStatus" the quantity of
results can be limited to show only the desired values. Further detailed informations of items meaning are
explained <a href=http://dev.mysql.com/doc/refman/5.7/en/server-status-variables.html>there</a>. <br>
<br><ul>
<b>Example</b> <br>
get &lt;name&gt; dbstatus <br>

# Only readings containing "uptime" and "qcache" in name will be created
</li>
<br><br>
</ul>
<li><b> dbValue &lt;SQL-statement&gt;</b> -
Executes the specified SQL-statement in <b>blocking</b> manner. Because of its mode of operation
this function is particular convenient for user own perl scripts. <br>
The input accepts multi line commands and delivers multi line results as well.
This command also accept the setting of SQL session variables like "SET @open:=NULL,
@closed:=NULL;". <br>
If several fields are selected and passed back, the fieds are separated by the separator defined
by <a href="#DbRepattr">attribute</a> "sqlResultFieldSep" (default "|"). Several result lines
are separated by newline ("\n"). <br>
This function only set/update status readings, the userExitFn function isn't called.
<br>
<br><ul>
<b>Examples for use in FHEMWEB</b> <br>
{fhem("get &lt;name&gt; dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device")} <br>
get &lt;name&gt; dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device <br>
{CommandGet(undef,"Rep.LogDB1 dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device")} <br>
</ul>

If you create a little routine in 99_myUtils, for example:
<br>
<pre>
sub dbval($$) {
my ($name,$cmd) = @_;
my $ret = CommandGet(undef,"$name dbValue $cmd");
return $ret;

# Only readings containing "version" and "query_cache" in name will be created
</li>
<br><br>
</ul>
<li><b> minTimestamp </b> - Identifies the oldest timestamp in the database (will be executed implicitely at FHEM start).
The timestamp is used as begin of data selection if no time attribut is set to determine the
start date.
</li>
<br><br>
<li><b> procinfo </b> - reports the existing database processes in a summary table (only MySQL). <br>
Typically only the own processes of the connection user (set in DbLog configuration file) will be
reported. If all precesses have to be reported, the global "PROCESS" right has to be granted to the
user. <br>
As of MariaDB 5.3 for particular SQL-Statements a progress reporting will be provided
(table row "PROGRESS"). So you can track, for instance, the degree of processing during an index
creation. <br>

<a name="DbRepattr"></a>
<b>Attributes</b>
<br>
<ul>
Using the module specific attributes you are able to define the scope of evaluation and the aggregation. <br>
The listed attrbutes are not completely relevant for every function of the module. The help of set/get-commands
contain explicitly which attributes are relevant for the specific command. <br><br>
<b>Note for SQL-Wildcard Usage:</b> <br>
Within the attribute values of "device" and "reading" you may use SQL-Wildcard "%", Character "_" is not supported as a wildcard.
The character "%" stands for any characters. <br>
This rule is valid to all functions <b>except</b> "insert", "importFromFile" and "deviceRename". <br>
The function "insert" doesn't allow setting the mentioned attributes containing the wildcard "%". <br>
In readings the wildcard character "%" will be replaced by "/" to meet the rules of allowed characters in readings.
<br><br>
<ul><ul>
<a name="aggregation"></a>
<li><b>aggregation </b> - Aggregation of Device/Reading-selections. Possible is hour, day, week, month or "no".
Delivers e.g. the count of database entries for a day (countEntries), Summation of
difference values of a reading (sumValue) and so on. Using aggregation "no" (default) an
aggregation don't happens but the output contaims all values of Device/Reading in the defined time period. </li> <br>
<a name="allowDeletion"></a>
<li><b>allowDeletion </b> - unlocks the delete-function </li> <br>
<a name="averageCalcForm"></a>
<li><b>averageCalcForm </b> - specifies the calculation variant of average peak by "averageValue". <br><br>
At the moment the following methods are implemented: <br><br>
<ul>
<table>
<colgroup> <col width=20%> <col width=80%> </colgroup>
<tr><td><b>avgArithmeticMean :</b> </td><td>the arithmetic average is calculated (default) </td></tr>
<tr><td style="vertical-align:top"><b>avgDailyMeanGWS :</b> <td>calculates the daily medium temperature according the
specifications of german weather service (pls. see "get &lt;name&gt; versionNotes 2"). <br>
This variant uses aggregation "day" automatically. </td></tr>
<tr><td><b>avgTimeWeightMean :</b> </td><td>calculates a time weighted average mean value is calculated </td></tr>
</table>
</ul>
</li><br>
<a name="countEntriesDetail"></a>
<li><b>countEntriesDetail </b> - If set, the function countEntries creates a detailed report of counted datasets of
every reading. By default only the summary of counted datasets is reported.
</li> <br>
<a name="device"></a>
<li><b>device </b> - Selection of particular or several devices. <br>
You can specify a list of devices separated by "," or use device specifications (devspec). <br>
Inside of lists or device specifications a SQL wildcard (%) will be evaluated as a normal
ASCII-character.
The device names are derived from device specification and the active devices in FHEM before
SQL selection will be carried out. <br>
If the the device, list or device specification is prepended by "EXCLUDE=",
the devices are excluded from database selection.
<br><br>
<ul>
<b>Examples:</b> <br>
<code>attr &lt;name&gt; device TYPE=DbRep</code> <br>
# select datasets of active present devices with Type "DbRep" <br>
<code>attr &lt;name&gt; device MySTP_5000</code> <br>

</li>
<a name="diffAccept"></a>
<li><b>diffAccept </b> - valid for function diffValue. diffAccept determines the threshold, up to that a calaculated
difference between two straight sequently datasets should be commenly accepted
(default = 20). <br>
Hence faulty DB entries with a disproportional high difference value will be eliminated and
don't tamper the result.
If a threshold overrun happens, the reading "diff_overrun_limit_&lt;diffLimit&gt;" will be
generated (&lt;diffLimit&gt; will be substituted with the present prest attribute value). <br>
The reading contains a list of relevant pair of values. Using verbose=3 this list will also
be reported in the FHEM logfile.
<br><br>
<ul>
Example report in logfile if threshold of diffAccept=10 overruns: <br><br>
DbRep Rep.STP5000.etotal -> data ignored while calc diffValue due to threshold overrun (diffAccept = 10): <br>
2016-04-09 08:50:50 0.0340 -> 2016-04-09 12:42:01 13.3440 <br><br>
# The first dataset with a value of 0.0340 is untypical low compared to the next value of 13.3440 and results a untypical
high difference value. <br>
# Now you have to decide if the (second) dataset should be deleted, ignored of the attribute diffAccept should be adjusted.

<a name="fastStart"></a>
<li><b>fastStart </b> - Usually every DbRep device is making a short connect to its database when FHEM is started to
retrieve some important informations and the reading "state" switches to "connected" on success.
If this attrbute is set, the initial database connection is executed not till then the
DbRep device is processing its first command. <br>
While the reading "state" is remaining in state "initialized" after FHEM-start.
This approach my be helpful if a lot of DbRep devices are defined.

Reading SqlResult. <br><br>
<b>json </b> - creates the Reading SqlResult as a JSON
coded hash.
Every hash-element consists of the serial number of the dataset (key)
and its value.
<br><br>
To process the result, you may use a userExitFn in 99_myUtils for example: <br>
<pre>
sub resfromjson {

# use your own processing from here for every hash-element
# e.g. output of every element that contains "Cam"
my $ke = $data->{$k};
if($ke =~ m/Cam/i) {
my ($res1,$res2) = split("\\|", $ke);
Log3($name, 1, "$name - extract element $k by userExitFn: ".$res1." ".$res2);
}
}
}
return;
}
</pre>
</ul>
<br>
</li>
<a name="timeYearPeriod"></a>
<li><b>timeYearPeriod </b> - By this attribute an annual time period will be determined for database data selection.
The time limits are calculated dynamically during execution time. Every time an annual period is determined.
Periods of less than a year are not possible to set. <br>
This attribute is particularly intended to make reports synchronous to an account period, e.g. of an energy- or gas provider.
<br><br>
<ul>
<b>Example:</b> <br><br>
attr &lt;name&gt; timeYearPeriod 06-25 06-24 <br><br>
# evaluates the database within the time limits 25. june AAAA and 24. june BBBB. <br>
# The year AAAA respectively year BBBB is calculated dynamically depending of the current date. <br>
# If the current date >= 25. june and =< 31. december, than AAAA = current year and BBBB = current year+1 <br>
# If the current date >= 01. january und =< 24. june, than AAAA = current year-1 and BBBB = current year
</ul>

<a name="timestamp_end"></a>
<li><b>timestamp_end </b> - end of data selection. If not set the current date/time combination will be used. <br>
The format of timestamp is as used with DbLog "YYYY-MM-DD HH:MM:SS". For the attributes "timestamp_begin", "timestamp_end"
you can also use one of the following entries. The timestamp-attribute will be dynamically set to:

# Analyzes the database between the time limits of the current year. <br>
</ul>
<br><br>
<b>Note </b> <br>
If the attribute "timeDiffToNow" will be set, the attributes "timestamp_begin" respectively "timestamp_end" will be deleted if they were set before.
The setting of "timestamp_begin" respectively "timestamp_end" causes the deletion of attribute "timeDiffToNow" if it was set before as well.
<br><br>
</li>
<a name="timeDiffToNow"></a>
<li><b>timeDiffToNow </b> - the <b>begin time </b> of data selection will be set to the timestamp <b>"&lt;current time&gt; -
&lt;timeDiffToNow&gt;"</b> dynamically (e.g. if set to 86400, the last 24 hours are considered by data
selection). The time period will be calculated dynamically at execution time.
<br><br>
<ul>
<b>Examples for input format:</b> <br>
<code>attr &lt;name&gt; timeDiffToNow 86400</code> <br>
# the start time is set to "current time - 86400 seconds" <br>
<code>attr &lt;name&gt; timeDiffToNow d:2 h:3 m:2 s:10</code> <br>

</li>
<a name="timeOlderThan"></a>
<li><b>timeOlderThan </b> - the <b>end time</b> of data selection will be set to the timestamp <b>"&lt;aktuelle Zeit&gt; -

<code>attr &lt;name&gt; timeOlderThan y:1.5</code> <br>
# the selection end time is set to "current time - 1.5 years" <br>
</ul>
<br>
If both attributes "timeDiffToNow" and "timeOlderThan" are set, the selection
period will be calculated between of these timestamps dynamically.
<br><br>
</li>
<a name="timeout"></a>
<li><b>timeout </b> - set the timeout-value for Blocking-Call Routines in background in seconds (default 86400) </li> <br>
<a name="userExitFn"></a>
<li><b>userExitFn </b> - provides an interface to execute user specific program code. <br>
To activate the interfaace at first you should implement the subroutine which will be
called by the interface in your 99_myUtls.pm as shown in by the example: <br>
<pre>
sub UserFunction {
my ($name,$reading,$value) = @_;
my $hash = $defs{$name};
...
# e.g. output transfered data
Log3 $name, 1, "UserExitFn $name called - transfer parameter are Reading: $reading, Value: $value " ;
...
return;
}
</pre>
The interface activation takes place by setting the subroutine name into the attribute.
Optional you may set a Reading:Value combination (Regex) as argument. If no Regex is
specified, all value combinations will be evaluated as "true" (related to .*:.*).
<br><br>
<ul>
<b>Example:</b> <br>
attr <device> userExitFn UserFunction .*:.* <br>
# "UserFunction" is the name of subroutine in 99_myUtils.pm.
</ul>
<br>
The interface works generally without and independent from Events.
If the attribute is set, after every reading generation the Regex will be evaluated.
If the evaluation was "true", set subroutine will be called.
For further processing following parameters will be forwarded to the function: <br><br>
<ul>
<li>$name - the name of the DbRep-Device </li>
<li>$reading - the name of the created reading </li>
<li>$value - the value of the reading </li>
</ul>
<br><br>
</li>
<a name="valueFilter"></a>
<li><b>valueFilter </b> - Regular expression (REGEXP) to filter datasets within particular functions. The REGEXP is
applied to a particular field or to the whole selected dataset (inclusive Device, Reading and
so on).
Please consider the explanations within the set-commands. Further information is available
with command "get &lt;name&gt; versionNotes 4". </li> <br>
</ul>
</ul></ul>
<a name="DbRepReadings"></a>
<b>Readings</b>
<br>
<ul>
Regarding to the selected operation the reasults will be shown as readings. At the beginning of a new operation all old readings will be deleted to avoid
that unsuitable or invalid readings would remain.<br><br>
In addition the following readings will be created: <br><br>
<ul><ul>
<li><b>state </b> - contains the current state of evaluation. If warnings are occured (state = Warning) compare Readings
"diff_overrun_limit_&lt;diffLimit&gt;" and "less_data_in_period" </li> <br>
<li><b>errortext </b> - description about the reason of an error state </li> <br>
<li><b>background_processing_time </b> - the processing time spent for operations in background/forked operation </li> <br>
<li><b>sql_processing_time </b> - the processing time wasted for all sql-statements used for an operation </li> <br>
<li><b>diff_overrun_limit_&lt;diffLimit&gt;</b> - contains a list of pairs of datasets which have overrun the threshold (&lt;diffLimit&gt;)
of calculated difference each other determined by attribute "diffAccept" (default=20). </li> <br>
<li><b>less_data_in_period </b> - contains a list of time periods within only one dataset was found. The difference calculation considers
the last value of the aggregation period before the current one. Valid for function "diffValue". </li> <br>
<li><b>SqlResult </b> - result of the last executed sqlCmd-command. The formatting can be specified
by <a href="#DbRepattr">attribute</a> "sqlResultFormat" </li> <br>
<li><b>sqlCmd </b> - contains the last executed sqlCmd-command </li> <br>
</ul></ul>
<br><br>
</ul>
<a name="DbRepAutoRename"></a>
<b>DbRep Agent - automatic change of device names in databases and DbRep-definitions after FHEM "rename" command</b>
<br>
<ul>
By the attribute "role" the role of DbRep-device will be configured. The standard role is "Client". If the role has changed to "Agent", the DbRep device
react automatically on renaming devices in your FHEM installation. The DbRep device is now called DbRep-Agent. <br><br>
By the DbRep-Agent the following features are activated when a FHEM-device has being renamed: <br><br>
<ul><ul>
<li> in the database connected to the DbRep-Agent (Internal Database) dataset containing the old device name will be searched and renamed to the
to the new device name in <b>all</b> affected datasets. </li> <br>
<li> in the DbLog-Device assigned to the DbRep-Agent the definition will be changed to substitute the old device name by the new one. Thereby the logging of
the renamed device will be going on in the database. </li> <br>
<li> in other existing DbRep-definitions with Type "Client" a possibly set attribute "device = old device name" will be changed to "device = new device name".
Because of that, reporting definitions will be kept consistent automatically if devices are renamed in FHEM. </li> <br>
</ul></ul>
The following restrictions take place if a DbRep device was changed to an Agent by setting attribute "role" to "Agent". These conditions will be activated
and checked: <br><br>
<ul><ul>
<li> within a FHEM installation only one DbRep-Agent can be configured for every defined DbLog-database. That means, if more than one DbLog-database is present,
you could define same numbers of DbRep-Agents as well as DbLog-devices are defined. </li> <br>
<li> after changing to DbRep-Agent role only the set-command "renameDevice" will be available and as well as a reduced set of module specific attributes will be
permitted. If a DbRep-device of privious type "Client" has changed an Agent, furthermore not permitted attributes will be deleted if set. </li> <br>
</ul></ul>
All activities like database changes and changes of other DbRep-definitions will be logged in FHEM Logfile with verbose=3. In order that the renameDevice
function don't running into timeout set the timeout attribute to an appropriate value, especially if there are databases with huge datasets to evaluate.
As well as all the other database operations of this module, the autorename operation will be executed nonblocking. <br><br>
<ul>
<b>Example </b> of definition of a DbRep-device as an Agent: <br><br>
<code>
define Rep.Agent DbRep LogDB <br>
attr Rep.Agent devStateIcon connected:10px-kreis-gelb .*disconnect:10px-kreis-rot .*done:10px-kreis-gruen <br>
attr Rep.Agent icon security <br>
attr Rep.Agent role Agent <br>
attr Rep.Agent room DbLog <br>
attr Rep.Agent showproctime 1 <br>
attr Rep.Agent stateFormat { ReadingsVal("$name","state", undef) eq "running" ? "renaming" : ReadingsVal("$name","state", undef). " &raquo;; ProcTime: ".ReadingsVal("$name","sql_processing_time", undef)." sec"} <br>
attr Rep.Agent timeout 86400 <br>
</code>
<br>
</ul>
<b>Note:</b> <br>
Even though the function itself is designed non-blocking, make sure the assigned DbLog-device
is operating in asynchronous mode to avoid FHEMWEB from blocking. <br><br>

<h3>DbRep</h3>
<ul>
<br>
Zweck des Moduls ist es, den Inhalt von DbLog-Datenbanken nach bestimmten Kriterien zu durchsuchen, zu managen, das Ergebnis hinsichtlich verschiedener
Aggregationen auszuwerten und als Readings darzustellen. Die Abgrenzung der zu berücksichtigenden Datenbankinhalte erfolgt durch die Angabe von Device, Reading und
die Zeitgrenzen für Auswertungsbeginn bzw. Auswertungsende. <br><br>
Fast alle Datenbankoperationen werden nichtblockierend ausgeführt. Auf Ausnahmen wird hingewiesen.
Die Ausführungszeit der (SQL)-Hintergrundoperationen kann optional ebenfalls als Reading bereitgestellt
werden (siehe <a href="#DbRepattr">Attribute</a>). <br>
Alle vorhandenen Readings werden vor einer neuen Operation gelöscht. Durch das Attribut "readingPreventFromDel" kann eine Komma separierte Liste von Readings
angegeben werden die nicht gelöscht werden sollen. <br><br>
Aktuell werden folgende Operationen unterstützt: <br><br>
<ul><ul>
<li> Selektion aller Datensätze innerhalb einstellbarer Zeitgrenzen </li>
<li> Darstellung der Datensätze einer Device/Reading-Kombination innerhalb einstellbarer Zeitgrenzen. </li>
<li> Selektion der Datensätze unter Verwendung von dynamisch berechneter Zeitgrenzen zum Ausführungszeitpunkt. </li>
<li> Dubletten-Hervorhebung bei Datensatzanzeige (fetchrows) </li>
<li> Berechnung der Anzahl von Datensätzen einer Device/Reading-Kombination unter Berücksichtigung von Zeitgrenzen
und verschiedenen Aggregationen. </li>
<li> Die Berechnung von Summen-, Differenz-, Maximum-, Minimum- und Durchschnittswerten numerischer Readings
in Zeitgrenzen und verschiedenen Aggregationen. </li>
<li> Speichern von Summen-, Differenz- , Maximum- , Minimum- und Durchschnittswertberechnungen in der Datenbank </li>
<li> Löschung von Datensätzen. Die Eingrenzung der Löschung kann durch Device und/oder Reading sowie fixer oder
dynamisch berechneter Zeitgrenzen zum Ausführungszeitpunkt erfolgen. </li>
<li> Export von Datensätzen in ein File im CSV-Format </li>
<li> Import von Datensätzen aus File im CSV-Format </li>
<li> Umbenennen von Device/Readings in Datenbanksätzen </li>
<li> Ändern von Reading-Werten (VALUES) in der Datenbank (changeValue) </li>
<li> automatisches Umbenennen von Device-Namen in Datenbanksätzen und DbRep-Definitionen nach FHEM "rename"

<li> Ausführen von beliebigen Benutzer spezifischen SQL-Kommandos (non-blocking) </li>
<li> Ausführen von beliebigen Benutzer spezifischen SQL-Kommandos (blocking) zur Verwendung in eigenem Code (dbValue) </li>
<li> Backups der FHEM-Datenbank im laufenden Betrieb erstellen (MySQL, SQLite) </li>
<li> senden des Dumpfiles zu einem FTP-Server nach dem Backup incl. Versionsverwaltung </li>

</ul></ul>
<br>
Zur Aktivierung der Funktion <b>Autorename</b> wird dem definierten DbRep-Device mit dem Attribut "role" die Rolle "Agent" zugewiesen. Die Standardrolle nach Definition
ist "Client". Mehr ist dazu im Abschnitt <a href="#DbRepAutoRename">DbRep-Agent</a> beschrieben. <br><br>
DbRep stellt dem Nutzer einen <b>UserExit</b> zur Verfügung. Über diese Schnittstelle kann der Nutzer in Abhängigkeit von
frei definierbaren Reading/Value-Kombinationen (Regex) eigenen Code zur Ausführung bringen. Diese Schnittstelle arbeitet
unabhängig von einer Eventgenerierung. Weitere Informationen dazu ist unter <a href="#DbRepattr">Attribut</a>
"userExitFn" beschrieben. <br><br>
Sobald ein DbRep-Device definiert ist, wird die Funktion <b>DbReadingsVal</b> zur Verfügung gestellt.
Mit dieser Funktion läßt sich, ähnlich dem allgemeinen ReadingsVal, der Wert eines Readings aus der Datenbank abrufen.
Die Funktionsausführung erfolgt blockierend.
Die Befehlssyntax ist: <br><br>
<ul>
<code>DbReadingsVal("&lt;name&gt;","&lt;device:reading&gt;","&lt;timestamp&gt;","&lt;default&gt;") </code> <br><br>
<b>Beispiele: </b><br>
$ret = DbReadingsVal("Rep.LogDB1","MyWetter:temperature","2018-01-13 08:00:00",""); <br>
attr &lt;name&gt; userReadings oldtemp {DbReadingsVal("Rep.LogDB1","MyWetter:temperature","2018-04-13 08:00:00","")}
<br><br>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>&lt;name&gt;</b> </td><td>: Name des abzufragenden DbRep-Device </td></tr>
<tr><td> <b>&lt;device:reading&gt;</b> </td><td>: Device:Reading dessen Wert geliefert werden soll </td></tr>
<tr><td> <b>&lt;timestamp&gt;</b> </td><td>: Zeitpunkt des zu liefernden Readingwertes (*) in der Form "YYYY-MM-DD hh:mm:ss" </td></tr>
<tr><td> <b>&lt;default&gt;</b> </td><td>: Defaultwert falls kein Readingwert ermittelt werden konnte </td></tr>
</table>
</ul>
<br>
(*) Es wird der zeitlich zu &lt;timestamp&gt; passendste Readingwert zurück geliefert, falls kein Wert exakt zu dem
angegebenen Zeitpunkt geloggt wurde.

<br>
</ul>
<b>Voraussetzungen </b> <br><br>
<ul>
Das Modul setzt den Einsatz einer oder mehrerer DbLog-Instanzen voraus. Es werden die Zugangsdaten dieser
Datenbankdefinition genutzt. <br>
Es werden nur Inhalte der Tabelle "history" berücksichtigt wenn nichts anderes beschrieben ist. <br><br>
Überblick welche anderen Perl-Module DbRep verwendet: <br><br>
Net::FTP (nur wenn FTP-Transfer nach Datenbank-Dump genutzt wird) <br>
Net::FTPSSL (nur wenn FTP-Transfer mit Verschlüsselung nach Datenbank-Dump genutzt wird) <br>
POSIX <br>
Time::HiRes <br>
Time::Local <br>
Scalar::Util <br>
DBI <br>
Color (FHEM-Modul) <br>
IO::Compress::Gzip <br>
IO::Uncompress::Gunzip <br>
Blocking (FHEM-Modul) <br><br>
Aus Performancegründen sollte zusätzlich folgender Index erstellt werden: <br>
<code>
CREATE INDEX Report_Idx ON `history` (TIMESTAMP, READING) USING BTREE;
</code>
</ul>
<br>
<a name="DbRepdefine"></a>
<b>Definition</b>
<br>
<ul>
<code>
define &lt;name&gt; DbRep &lt;Name der DbLog-Instanz&gt;
</code>
<br><br>
(&lt;Name der DbLog-Instanz&gt; - es wird der Name der auszuwertenden DBLog-Datenbankdefinition angegeben <b>nicht</b> der Datenbankname selbst)
</ul>
<br><br>
<a name="DbRepset"></a>
<b>Set </b>
<ul>
Zur Zeit gibt es folgende Set-Kommandos. Über sie werden die Auswertungen angestoßen und definieren selbst die Auswertungsvariante.
Nach welchen Kriterien die Datenbankinhalte durchsucht werden und die Aggregation erfolgt, wird durch <a href="#DbRepattr">Attribute</a> gesteuert.
<br><br>
<ul><ul>
<li><b> averageValue [display | writeToDB]</b>
- berechnet einen Durchschnittswert des Datenbankfelds "VALUE" in den
gegebenen Zeitgrenzen ( siehe <a href="#DbRepattr">Attribute</a>).
Es muss das auszuwertende Reading über das <a href="#DbRepattr">Attribut</a> "reading"
angegeben sein. <br>
Mit dem Attribut "averageCalcForm" wird die Berechnungsvariante zur Mittelwertermittlung definiert.
Ist keine oder die Option "display" angegeben, werden die Ergebnisse nur angezeigt. Mit
der Option "writeToDB" werden die Berechnungsergebnisse mit einem neuen Readingnamen
in der Datenbank gespeichert. <br>
Der neue Readingname wird aus einem Präfix und dem originalen Readingnamen gebildet,
wobei der originale Readingname durch das Attribut "readingNameMap" ersetzt werden kann.
Der Präfix setzt sich aus der Bildungsfunktion und der Aggregation zusammen. <br>
Der Timestamp der neuen Readings in der Datenbank wird von der eingestellten Aggregationsperiode
abgeleitet, sofern kein eindeutiger Zeitpunkt des Ergebnisses bestimmt werden kann.
Das Feld "EVENT" wird mit "calculated" gefüllt.<br><br>
<ul>
<b>Beispiel neuer Readingname gebildet aus dem Originalreading "totalpac":</b> <br>
avgam_day_totalpac <br>
# &lt;Bildungsfunktion&gt;_&lt;Aggregation&gt;_&lt;Originalreading&gt; <br>
</ul>
<br>

</ul>
<br>
<br>
</li> <br>
<li><b> cancelDump </b> - bricht einen laufenden Datenbankdump ab. </li> <br>
<li><b> changeValue </b> - ändert den gespeicherten Wert eines Readings.
Ist die Selektion auf bestimmte Device/Reading-Kombinationen durch die
<a href="#DbRepattr">Attribute</a> "device" bzw. "reading" beschränkt, werden sie genauso
berücksichtigt wie gesetzte Zeitgrenzen (Attribute time.*). <br>
Fehlen diese Beschränkungen, wird die gesamte Datenbank durchsucht und der angegebene Wert
geändert. <br><br>
<ul>
<b>Syntax: </b> <br>
set &lt;name&gt; changeValue "&lt;alter String&gt;","&lt;neuer String&gt;" <br><br>
Die Strings werden in Doppelstrich eingeschlossen und durch Komma getrennt.
Dabei kann "String" sein: <br>
<table>
<colgroup> <col width=15%> <col width=85%> </colgroup>
<tr><td style="vertical-align:top"><b>&lt;old string&gt; :</b> <td><li>ein einfacher String mit/ohne Leerzeichen, z.B. "OL 12" </li>

Dem Perl-Ausdruck werden die Variablen $VALUE und $UNIT übergeben. Sie können innerhalb
des Perl-Code geändert werden. Der zurückgebene Wert von $VALUE und $UNIT wird in dem Feld
VALUE bzw. UNIT des Datensatzes gespeichert. </li></td></tr>
</table>
<br>
<b>Beispiele: </b> <br>
set &lt;name&gt; changeValue "OL","12 OL" <br>
# der alte Feldwert "OL" wird in "12 OL" geändert. <br><br>
set &lt;name&gt; changeValue "%OL%","12 OL" <br>
# enthält das Feld VALUE den Teilstring "OL", wird es in "12 OL" geändert. <br><br>
set &lt;name&gt; changeValue "12 kWh","{($VALUE,$UNIT) = split(" ",$VALUE)}" <br>
# der alte Feldwert "12 kWh" wird in VALUE=12 und UNIT=kWh gesplittet und in den Datenbankfeldern gespeichert <br><br>
set &lt;name&gt; changeValue "24%","{$VALUE = (split(" ",$VALUE))[0]}" <br>
# beginnt der alte Feldwert mit "24", wird er gesplittet und VALUE=24 gespeichert (z.B. "24 kWh")

<br>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, sollte das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden (Tabellen-Lock). <br><br>
</li> <br>
</ul>
<li><b> countEntries [history | current] </b>
- liefert die Anzahl der Tabelleneinträge (default: history) in den gegebenen
Zeitgrenzen (siehe <a href="#DbRepattr">Attribute</a>).
Sind die Timestamps nicht gesetzt, werden alle Einträge der Tabelle gezählt.
Beschränkungen durch die <a href="#DbRepattr">Attribute</a> Device bzw. Reading
gehen in die Selektion mit ein. <br>
Standardmäßig wird die Summe aller Datensätze, gekennzeichnet mit "ALLREADINGS", erstellt.
Ist das Attribut "countEntriesDetail" gesetzt, wird die Anzahl jedes einzelnen Readings
zusätzlich ausgegeben. <br><br>
Die für diese Funktion relevanten Attribute sind: <br><br>
<ul>

</table>
</ul>
<br>
</li> <br>
<li><b> delDoublets [adviceDelete | delete]</b> - zeigt bzw. löscht doppelte / mehrfach vorkommende Datensätze.
Dazu wird Timestamp, Device,Reading und Value ausgewertet. <br>
Die <a href="#DbRepattr">Attribute</a> zur Aggregation,Zeit-,Device- und Reading-Abgrenzung werden dabei
berücksichtigt. Ist das Attribut "aggregation" nicht oder auf "no" gesetzt, wird im Standard die Aggregation
"day" verwendet.
<br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>adviceDelete</b> </td><td>: ermittelt die zu löschenden Datensätze (es wird nichts gelöscht !) </td></tr>

</table>
</ul>
<br>
Aus Sicherheitsgründen muss das <a href="#DbRepattr">Attribut</a> "allowDeletion" für die "delete" Option
gesetzt sein. <br>
Die Anzahl der anzuzeigenden Datensätze des Kommandos "delDoublets adviceDelete" ist zunächst
begrenzt (default 1000) und kann durch das <a href="#DbRepattr">Attribut</a> "limit" angepasst
werden.
Die Einstellung von "limit" hat keinen Einfluss auf die "delDoublets delete" Funktion, sondern
beeinflusst <b>NUR</b> die Anzeige der Daten. <br>
Vor und nach der Ausführung von "delDoublets" kann ein FHEM-Kommando bzw. Perl-Routine ausgeführt
werden. (siehe <a href="#DbRepattr">Attribute</a> "executeBeforeProc", "executeAfterProc")
<br><br>
<ul>
<b>Beispiel:</b> <br><br>

<br>
Im Werteteil der erzeugten Readings wird nach "_|_" die Anzahl der entsprechenden Datensätze
ausgegeben, die mit "delDoublets delete" gelöscht werden.

<li><b> delSeqDoublets [adviceRemain | adviceDelete | delete]</b> - zeigt bzw. löscht aufeinander folgende identische Datensätze.
Dazu wird Device,Reading und Value ausgewertet. Nicht gelöscht werden der erste und der letzte Datensatz
einer Aggregationsperiode (z.B. hour, day, week usw.) sowie die Datensätze vor oder nach einem Wertewechsel
(Datenbankfeld VALUE). <br>
Die <a href="#DbRepattr">Attribute</a> zur Aggregation,Zeit-,Device- und Reading-Abgrenzung werden dabei
berücksichtigt. Ist das Attribut "aggregation" nicht oder auf "no" gesetzt, wird als Standard die Aggregation
"day" verwendet. Für Datensätze mit numerischen Werten kann mit dem <a href="#DbRepattr">Attribut</a>
"seqDoubletsVariance" eine Abweichung eingestellt werden, bis zu der aufeinander folgende numerische Werte als
identisch angesehen und gelöscht werden sollen.

</ul>
<br>
Aus Sicherheitsgründen muss das <a href="#DbRepattr">Attribut</a> "allowDeletion" für die "delete" Option
gesetzt sein. <br>
Die Anzahl der anzuzeigenden Datensätze der Kommandos "delSeqDoublets adviceDelete", "delSeqDoublets adviceRemain" ist
zunächst begrenzt (default 1000) und kann durch das <a href="#DbRepattr">Attribut</a> "limit" angepasst werden.
Die Einstellung von "limit" hat keinen Einfluss auf die "delSeqDoublets delete" Funktion, sondern beeinflusst <b>NUR</b> die
Anzeige der Daten. <br>
Vor und nach der Ausführung von "delSeqDoublets" kann ein FHEM-Kommando bzw. Perl-Routine ausgeführt werden.

</li>
<li><b> deviceRename &lt;old_name&gt;,&lt;new_name&gt;</b> -
benennt den Namen eines Device innerhalb der angeschlossenen Datenbank (Internal DATABASE) um.
Der Gerätename wird immer in der <b>gesamten</b> Datenbank umgesetzt. Eventuell gesetzte
Zeitgrenzen oder Beschränkungen durch die <a href="#DbRepattr">Attribute</a> Device bzw.
Reading werden nicht berücksichtigt. <br><br>
<ul>
<b>Beispiel: </b><br>
set &lt;name&gt; deviceRename ST_5000,ST5100 <br>
# Die Anzahl der umbenannten Device-Datensätze wird im Reading "device_renamed" ausgegeben. <br>
# Wird der umzubenennende Gerätename in der Datenbank nicht gefunden, wird eine WARNUNG im Reading "device_not_renamed" ausgegeben. <br>
# Entsprechende Einträge erfolgen auch im Logfile mit verbose=3
<br><br>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, sollte das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden (Tabellen-Lock). <br><br>
</li> <br>
</ul>
<li><b> diffValue [display | writeToDB] </b>
- berechnet den Differenzwert des Datenbankfelds "VALUE" in den Zeitgrenzen (Attribute) "timestamp_begin", "timestamp_end" bzw "timeDiffToNow / timeOlderThan".
Es muss das auszuwertende Reading im Attribut "reading" angegeben sein.
Diese Funktion ist z.B. zur Auswertung von Eventloggings sinnvoll, deren Werte sich fortlaufend erhöhen und keine Wertdifferenzen wegschreiben. <br>
Es wird immer die Differenz aus dem Value-Wert des ersten verfügbaren Datensatzes und dem Value-Wert des letzten verfügbaren Datensatzes innerhalb der angegebenen
Zeitgrenzen/Aggregation gebildet, wobei ein Übertragswert der Vorperiode (Aggregation) zur darauf folgenden Aggregationsperiode
berücksichtigt wird sofern diese einen Value-Wert enhtält. <br>
Dabei wird ein Zählerüberlauf (Neubeginn bei 0) mit berücksichtigt (vergleiche <a href="#DbRepattr">Attribut</a> "diffAccept"). <br>
Wird in einer auszuwertenden Zeit- bzw. Aggregationsperiode nur ein Datensatz gefunden, kann die Differenz in Verbindung mit dem
Differenzübertrag der Vorperiode berechnet werden. in diesem Fall kann es zu einer logischen Ungenauigkeit in der Zuordnung der Differenz
zu der Aggregationsperiode kommen. Deswegen wird eine Warnung im "state" und das
Reading "less_data_in_period" mit einer Liste der betroffenen Perioden wird erzeugt. <br><br>
<ul>
<b>Hinweis: </b><br>
Im Auswertungs- bzw. Aggregationszeitraum (Tag, Woche, Monat, etc.) sollten dem Modul pro Periode mindestens ein Datensatz
zu Beginn und ein Datensatz gegen Ende des Aggregationszeitraumes zur Verfügung stehen um eine möglichst genaue Auswertung
der Differenzwerte vornehmen zu können.
<br>
<br>
</ul>
Ist keine oder die Option "display" angegeben, werden die Ergebnisse nur angezeigt. Mit
der Option "writeToDB" werden die Berechnungsergebnisse mit einem neuen Readingnamen
in der Datenbank gespeichert. <br>
Der neue Readingname wird aus einem Präfix und dem originalen Readingnamen gebildet,
wobei der originale Readingname durch das Attribut "readingNameMap" ersetzt werden kann.
Der Präfix setzt sich aus der Bildungsfunktion und der Aggregation zusammen. <br>
Der Timestamp der neuen Readings in der Datenbank wird von der eingestellten Aggregationsperiode
abgeleitet, sofern kein eindeutiger Zeitpunkt des Ergebnisses bestimmt werden kann.
Das Feld "EVENT" wird mit "calculated" gefüllt.<br><br>

<li><b> dumpMySQL [clientSide | serverSide]</b>
- erstellt einen Dump der angeschlossenen MySQL-Datenbank. <br>
Abhängig von der ausgewählten Option wird der Dump auf der Client- bzw. Serverseite erstellt. <br>
Die Varianten unterscheiden sich hinsichtlich des ausführenden Systems, des Erstellungsortes, der
Attributverwendung, des erzielten Ergebnisses und der benötigten Hardwareressourcen. <br>
Die Option "clientSide" benötigt z.B. eine leistungsfähigere Hardware des FHEM-Servers, sichert aber alle
Tabellen inklusive eventuell angelegter Views. <br>
Mit dem Attribut "dumpCompress" kann eine Komprimierung der erstellten Dumpfiles eingeschaltet werden.
<br><br>
<ul>
<b><u>Option clientSide</u></b> <br>
Der Dump wird durch den Client (FHEM-Rechner) erstellt und per default im log-Verzeichnis des Clients
gespeichert.
Das Zielverzeichnis kann mit dem <a href="#DbRepattr">Attribut</a> "dumpDirLocal" verändert werden und muß auf
dem Client durch FHEM beschreibbar sein. <br>
Vor dem Dump kann eine Tabellenoptimierung (Attribut "optimizeTablesBeforeDump") oder ein FHEM-Kommando
(Attribut "executeBeforeProc") optional zugeschaltet werden.
Nach dem Dump kann ebenfalls ein FHEM-Kommando (siehe Attribut "executeAfterProc") ausgeführt werden. <br><br>
<b>Achtung ! <br>
Um ein Blockieren von FHEM zu vermeiden, muß DbLog im asynchronen Modus betrieben werden wenn die
Tabellenoptimierung verwendet wird ! </b> <br><br>
Über die <a href="#DbRepattr">Attribute</a> "dumpMemlimit" und "dumpSpeed" kann das Laufzeitverhalten der
Funktion beeinflusst werden um eine Optimierung bezüglich Performance und Ressourcenbedarf zu erreichen. <br><br>
Die für "dumpMySQL clientSide" relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> dumpComment </td><td>: User-Kommentar im Dumpfile </td></tr>
<tr><td> dumpCompress </td><td>: Komprimierung des Dumpfiles nach der Erstellung </td></tr>

<tr><td> optimizeTablesBeforeDump </td><td>: Tabelloptimierung vor dem Dump ausführen </td></tr>
</table>
</ul>
<br>
Nach einem erfolgreichen Dump werden alte Dumpfiles gelöscht und nur die Anzahl Files, definiert durch
das Attribut "dumpFilesKeep" (default: 3), verbleibt im Zielverzeichnis "dumpDirLocal". Falls "dumpFilesKeep = 0"
gesetzt ist, werden alle Dumpfiles (auch das aktuell erstellte File), gelöscht.
Diese Einstellung kann sinnvoll sein, wenn FTP aktiviert ist
und die erzeugten Dumps nur im FTP-Zielverzeichnis erhalten bleiben sollen. <br><br>
Die <b>Namenskonvention der Dumpfiles</b> ist: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.sql[.gzip] <br><br>
Um die Datenbank aus dem Dumpfile wiederherzustellen kann das Kommmando: <br><br>
<ul>
set &lt;name&gt; restoreMySQL &lt;filename&gt; <br><br>
</ul>
verwendet werden. <br><br>
Das erzeugte Dumpfile (unkomprimiert) kann ebenfalls mit: <br><br>
<ul>
mysql -u &lt;user&gt; -p &lt;dbname&gt; < &lt;filename&gt;.sql <br><br>
</ul>
auf dem MySQL-Server ausgeführt werden um die Datenbank aus dem Dump wiederherzustellen. <br><br>
<br>
<b><u>Option serverSide</u></b> <br>
Der Dump wird durch den MySQL-Server erstellt und per default im Home-Verzeichnis des MySQL-Servers
gespeichert. <br>
Es wird die gesamte history-Tabelle (nicht current-Tabelle) <b>im CSV-Format</b> ohne
Einschränkungen exportiert. <br>
Vor dem Dump kann eine Tabellenoptimierung (Attribut "optimizeTablesBeforeDump")
optional zugeschaltet werden . <br><br>
<b>Achtung ! <br>
Um ein Blockieren von FHEM zu vermeiden, muß DbLog im asynchronen Modus betrieben werden wenn die
Tabellenoptimierung verwendet wird ! </b> <br><br>
Vor und nach dem Dump kann ein FHEM-Kommando (siehe Attribute "executeBeforeProc", "executeAfterProc") ausgeführt
werden. <br><br>
Die für "dumpMySQL serverSide" relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> dumpDirRemote </td><td>: das Erstellungsverzeichnis des Dumpfile auf dem entfernten Server </td></tr>
<tr><td> dumpCompress </td><td>: Komprimierung des Dumpfiles nach der Erstellung </td></tr>

</table>
</ul>
<br>
Das Zielverzeichnis kann mit dem <a href="#DbRepattr">Attribut</a> "dumpDirRemote" verändert werden.
Es muß sich auf dem MySQL-Host gefinden und durch den MySQL-Serverprozess beschreibbar sein. <br>
Der verwendete Datenbankuser benötigt das "FILE"-Privileg. <br><br>
<b>Hinweis:</b> <br>
Soll die interne Versionsverwaltung und die Dumpfilekompression des Moduls genutzt, sowie die Größe des erzeugten
Dumpfiles ausgegeben werden, ist das Verzeichnis "dumpDirRemote" des MySQL-Servers auf dem Client zu mounten
und im <a href="#DbRepattr">Attribut</a> "dumpDirLocal" dem DbRep-Device bekannt zu machen. <br>
Gleiches gilt wenn der FTP-Transfer nach dem Dump genutzt werden soll (Attribut "ftpUse" bzw. "ftpUseSSL").
<br><br>
<ul>
<b>Beispiel: </b> <br>
attr &lt;name&gt; dumpDirRemote /volume1/ApplicationBackup/dumps_FHEM/ <br>
attr &lt;name&gt; dumpDirLocal /sds1/backup/dumps_FHEM/ <br>
attr &lt;name&gt; dumpFilesKeep 2 <br><br>
# Der Dump wird remote auf dem MySQL-Server im Verzeichnis '/volume1/ApplicationBackup/dumps_FHEM/'
erstellt. <br>
# Die interne Versionsverwaltung sucht im lokal gemounteten Verzeichnis '/sds1/backup/dumps_FHEM/'
vorhandene Dumpfiles und löscht diese bis auf die zwei letzten Versionen. <br>
<br>
</ul>
Wird die interne Versionsverwaltung genutzt, werden nach einem erfolgreichen Dump alte Dumpfiles gelöscht
und nur die Anzahl "dumpFilesKeep" (default: 3) verbleibt im Zielverzeichnis "dumpDirRemote".
FHEM benötigt in diesem Fall Schreibrechte auf dem Verzeichnis "dumpDirLocal". <br><br>
Die <b>Namenskonvention der Dumpfiles</b> ist: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.csv[.gzip] <br><br>
Ein Restore der Datenbank aus diesem Backup kann durch den Befehl: <br><br>
<ul>
set &lt;name&gt; &lt;restoreMySQL&gt; &lt;filename&gt;.csv[.gzip] <br><br>
</ul>
gestartet werden. <br><br>
<b><u>FTP Transfer nach Dump</u></b> <br>
Wenn diese Möglichkeit genutzt werden soll, ist das <a href="#DbRepattr">Attribut</a> "ftpUse" oder
"ftpUseSSL" zu setzen. Letzteres gilt wenn eine verschlüsselte Übertragung genutzt werden soll. <br>
Das Modul übernimmt ebenfalls die Versionierung der Dumpfiles im FTP-Zielverzeichnis mit Hilfe des Attributes
"ftpDumpFilesKeep".
Für die FTP-Übertragung relevante <a href="#DbRepattr">Attribute</a> sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> ftpUse </td><td>: FTP Transfer nach dem Dump wird eingeschaltet (ohne SSL Verschlüsselung) </td></tr>
<tr><td> ftpUser </td><td>: User zur Anmeldung am FTP-Server, default: anonymous </td></tr>
<tr><td> ftpUseSSL </td><td>: FTP Transfer mit SSL Verschlüsselung nach dem Dump wird eingeschaltet </td></tr>
<tr><td> ftpDebug </td><td>: Debugging des FTP Verkehrs zur Fehlersuche </td></tr>
<tr><td> ftpDir </td><td>: Verzeichnis auf dem FTP-Server in welches das File übertragen werden soll (default: "/") </td></tr>
<tr><td> ftpDumpFilesKeep </td><td>: Es wird die angegebene Anzahl Dumpfiles im &lt;ftpDir&gt; belassen (default: 3) </td></tr>
<tr><td> ftpPassive </td><td>: setzen wenn passives FTP verwendet werden soll </td></tr>
<tr><td> ftpPort </td><td>: FTP-Port, default: 21 </td></tr>
<tr><td> ftpPwd </td><td>: Passwort des FTP-Users, default nicht gesetzt </td></tr>
<tr><td> ftpServer </td><td>: Name oder IP-Adresse des FTP-Servers. <b>notwendig !</b> </td></tr>
<tr><td> ftpTimeout </td><td>: Timeout für die FTP-Verbindung in Sekunden (default: 30). </td></tr>
</table>
</ul>
<br>
<br>
</ul>
</li><br>
<li><b> dumpSQLite </b> - erstellt einen Dump der angeschlossenen SQLite-Datenbank. <br>
Diese Funktion nutzt die SQLite Online Backup API und ermöglicht es konsistente Backups der SQLite-DB
in laufenden Betrieb zu erstellen.
Der Dump wird per default im log-Verzeichnis des FHEM-Rechners gespeichert.
Das Zielverzeichnis kann mit dem <a href="#DbRepattr">Attribut</a> "dumpDirLocal" verändert werden und muß
durch FHEM beschreibbar sein.
Vor dem Dump kann optional eine Tabellenoptimierung (Attribut "optimizeTablesBeforeDump")
zugeschaltet werden.
<br><br>
<b>Achtung ! <br>
Um ein Blockieren von FHEM zu vermeiden, muß DbLog im asynchronen Modus betrieben werden wenn die
Tabellenoptimierung verwendet wird ! </b> <br><br>
Vor und nach dem Dump kann ein FHEM-Kommando (siehe Attribute "executeBeforeProc", "executeAfterProc")
ausgeführt werden. <br><br>
Die für diese Funktion relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> dumpCompress </td><td>: Komprimierung des Dumpfiles nach der Erstellung </td></tr>
<tr><td> dumpDirLocal </td><td>: Directory des lokal gemounteten dumpDirRemote-Verzeichnisses </td></tr>
<tr><td> dumpFilesKeep </td><td>: Anzahl der aufzubwahrenden Dumpfiles </td></tr>
<tr><td> executeBeforeProc </td><td>: ausführen FHEM Kommando (oder perl-Routine) vor dem Dump </td></tr>
<tr><td> executeAfterProc </td><td>: ausführen FHEM Kommando (oder perl-Routine) nach dem Dump </td></tr>
<tr><td> optimizeTablesBeforeDump </td><td>: Tabelloptimierung vor dem Dump ausführen </td></tr>
</table>
</ul>
<br>
Nach einem erfolgreichen Dump werden alte Dumpfiles gelöscht und nur die Anzahl Files, definiert durch das
Attribut "dumpFilesKeep" (default: 3), verbleibt im Zielverzeichnis "dumpDirLocal". Falls "dumpFilesKeep = 0" gesetzt, werden
alle Dumpfiles (auch das aktuell erstellte File), gelöscht. Diese Einstellung kann sinnvoll sein, wenn FTP aktiviert ist
und die erzeugten Dumps nur im FTP-Zielverzeichnis erhalten bleiben sollen. <br><br>
Die <b>Namenskonvention der Dumpfiles</b> ist: &lt;dbname&gt;_&lt;date&gt;_&lt;time&gt;.sqlitebkp[.gzip] <br><br>
Die Datenbank kann mit "set &lt;name&gt; restoreSQLite &lt;Filename&gt;" wiederhergestellt
werden. <br>
Das erstellte Dumpfile kann auf einen FTP-Server übertragen werden. Siehe dazu die Erläuterungen
unter "dumpMySQL". <br><br>
</li><br>
<li><b> eraseReadings </b> - Löscht alle angelegten Readings im Device, außer dem Reading "state" und Readings, die in der
Ausnahmeliste definiert mit Attribut "readingPreventFromDel" enthalten sind.
</li><br>
<li><b> exportToFile [&lt;File&gt;] </b>
- exportiert DB-Einträge im CSV-Format in den gegebenen Zeitgrenzen. <br>
Einschränkungen durch die <a href="#DbRepattr">Attribute</a> "device" bzw. "reading" gehen in die Selektion mit ein.
Der Dateiname wird durch das <a href="#DbRepattr">Attribut</a> "expimpfile" bestimmt. <br>
Alternativ kann die Datei (/Pfad/Datei) als Kommando-Option angegeben werden und übersteuert ein
eventuell gesetztes Attribut "expimpfile". Der Dateiname kann Wildcards enthalten (siehe Attribut "expimpfile").
<br>
Durch das Attribut "aggregation" wird der Export der Datensätze in Zeitscheiben der angegebenen Aggregation
vorgenommen. Ist z.B. "aggregation = month" gesetzt, werden die Daten in monatlichen Paketen selektiert und in
das Exportfile geschrieben. Dadurch wird die Hauptspeicherverwendung optimiert wenn sehr große Datenmengen
exportiert werden sollen und vermeidet den "died prematurely" Abbruchfehler. <br><br>
Die für diese Funktion relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>aggregation</b> </td><td>: Festlegung der Selektionspaketierung </td></tr>
<tr><td> <b>device</b> </td><td>: einschließen oder ausschließen von Datensätzen die &lt;device&gt; enthalten </td></tr>

</table>
</ul>
</li><br>
<li><b> fetchrows [history|current] </b>
- liefert <b>alle</b> Tabelleneinträge (default: history)
in den gegebenen Zeitgrenzen bzw. Selektionsbedingungen durch die <a href="#DbRepattr">Attribute</a>
"device" und "reading".
Eine evtl. gesetzte Aggregation wird dabei <b>nicht</b> berücksichtigt. <br>
Die Leserichtung in der Datenbank kann durch das <a href="#DbRepattr">Attribut</a>
"fetchRoute" bestimmt werden. <br><br>
Jedes Ergebnisreading setzt sich aus dem Timestring des Datensatzes, einem Index, dem Device
und dem Reading zusammen.
Die Funktion fetchrows ist in der Lage, mehrfach vorkommende Datensätze (Dubletten) zu erkennen.
Solche Dubletten sind mit einem Index > 1 gekennzeichnet. <br>
Dubletten können mit dem Attribut "fetchMarkDuplicates" farblich hervorgehoben werden. <br><br>
<b>Hinweis:</b> <br>
Hervorgehobene Readings werden nach einem Restart bzw. nach rereadcfg nicht mehr angezeigt da
sie nicht im statefile gesichert werden (Verletzung erlaubter Readingnamen durch Formatierung).
<br><br>
Dieses Attribut ist mit einigen Farben vorbelegt, kann aber mit dem colorpicker-Widget
überschrieben werden: <br><br>
<ul>
<code>
attr &lt;name&gt; widgetOverride fetchMarkDuplicates:colorpicker
</code>
</ul>
<br>
Die Ergebnisreadings von fetchrows sind nach folgendem Schema aufgebaut: <br><br>
<ul>
<b>Beispiel:</b> <br>
2017-10-22_03-04-43__1__SMA_Energymeter__Bezug_WirkP_Kosten_Diff <br>

<br>
<b>Hinweis:</b> <br>
Auch wenn das Modul bezüglich der Datenbankabfrage nichtblockierend arbeitet, kann eine
zu große Ergebnismenge (Anzahl Zeilen bzw. Readings) die Browsersesssion bzw. FHEMWEB
blockieren. Aus diesem Grund wird die Ergebnismenge mit dem
<a href="#limit">Attribut</a> "limit" begrenzt. Bei Bedarf kann dieses Attribut
geändert werden, falls eine Anpassung der Selektionsbedingungen nicht möglich oder
gewünscht ist. <br><br>
</li> <br>
<li><b> insert </b> - Manuelles Einfügen eines Datensatzes in die Tabelle "history". Obligatorisch sind Eingabewerte für Datum, Zeit und Value.
Die Werte für die DB-Felder Type bzw. Event werden mit "manual" gefüllt, sowie die Werte für Device, Reading aus den gesetzten <a href="#DbRepattr">Attributen </a> genommen. <br><br>
<ul>
<b>Eingabeformat: </b> Datum,Zeit,Value,[Unit] <br>
# Unit ist optional, Attribute "reading" und "device" müssen gesetzt sein <br>
# Soll "Value=0" eingefügt werden, ist "Value = 0.0" zu verwenden. <br><br>
<b>Beispiel: </b> 2016-08-01,23:00:09,TestValue,TestUnit <br>
# Es sind KEINE Leerzeichen im Feldwert erlaubt !<br>
<br>
<b>Hinweis: </b><br>
Bei der Eingabe ist darauf zu achten dass im beabsichtigten Aggregationszeitraum (Tag, Woche, Monat, etc.) MINDESTENS zwei
Datensätze für die Funktion diffValue zur Verfügung stehen. Ansonsten kann keine Differenz berechnet werden und diffValue
gibt in diesem Fall "0" in der betroffenen Periode aus !
<br>
<br>
</li>
</ul>
<li><b> importFromFile [&lt;File&gt;] </b>
- importiert Datensätze im CSV-Format aus einer Datei in die Datenbank. <br>
Der Dateiname wird durch das <a href="#DbRepattr">Attribut</a> "expimpfile" bestimmt. <br>
Alternativ kann die Datei (/Pfad/Datei) als Kommando-Option angegeben werden und übersteuert ein
eventuell gesetztes Attribut "expimpfile". Der Dateiname kann Wildcards enthalten (siehe
Attribut "expimpfile"). <br><br>
<ul>
<b>Datensatzformat: </b> <br>
"TIMESTAMP","DEVICE","TYPE","EVENT","READING","VALUE","UNIT" <br><br>
# Die Felder "TIMESTAMP","DEVICE","TYPE","EVENT","READING" und "VALUE" müssen gesetzt sein. Das Feld "UNIT" ist optional.
Der Fileinhalt wird als Transaktion importiert, d.h. es wird der Inhalt des gesamten Files oder, im Fehlerfall, kein Datensatz des Files importiert.
Wird eine umfangreiche Datei mit vielen Datensätzen importiert, sollte KEIN verbose=5 gesetzt werden. Es würden in diesem Fall sehr viele Sätze in
das Logfile geschrieben werden was FHEM blockieren oder überlasten könnte. <br><br>
<b>Beispiel: </b> <br>
"2016-09-25 08:53:56","STP_5000","SMAUTILS","etotal: 11859.573","etotal","11859.573","" <br>

<li><b> optimizeTables </b> - optimiert die Tabellen in der angeschlossenen Datenbank (MySQL). <br>
Vor und nach der Optimierung kann ein FHEM-Kommando ausgeführt werden.
(siehe <a href="#DbRepattr">Attribute</a> "executeBeforeProc", "executeAfterProc")
<br><br>
<ul>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, muß das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden. <br><br>
</li>
</ul><br>
<li><b> readingRename </b> - benennt den Namen eines Readings innerhalb der angeschlossenen Datenbank (siehe Internal DATABASE) um.
Der Readingname wird immer in der <b>gesamten</b> Datenbank umgesetzt. Eventuell
gesetzte Zeitgrenzen oder Beschränkungen durch die <a href="#DbRepattr">Attribute</a>
Device bzw. Reading werden nicht berücksichtigt. <br><br>
<ul>
<b>Beispiel: </b><br>
set &lt;name&gt; readingRename &lt;alter Readingname&gt;,&lt;neuer Readingname&gt; <br>
# Die Anzahl der umbenannten Device-Datensätze wird im Reading "reading_renamed"
ausgegeben. <br>
# Wird der umzubenennende Readingname in der Datenbank nicht gefunden, wird eine
WARNUNG im Reading "reading_not_renamed" ausgegeben. <br>
# Entsprechende Einträge erfolgen auch im Logfile mit verbose=3.
<br><br>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, sollte das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden (Tabellen-Lock). <br><br>
</li> <br>
</ul>
<li><b> reduceLog [average[=day]] </b> <br>
Reduziert historische Datensätze innerhalb der durch die "time.*"-Attribute bestimmten
Zeitgrenzen auf einen Eintrag (den ersten) pro Stunde je Device & Reading.
Es muss mindestens eines der "time.*"-Attribute gesetzt sein (siehe Tabelle unten).
Die jeweils fehlende Zeitabgrenzung wird in diesem Fall durch das Modul errechnet.
<br><br>
Durch die optionale Angabe von 'average' wird nicht nur die Datenbank bereinigt, sondern
alle numerischen Werte einer Stunde werden auf einen einzigen Mittelwert reduziert.
Mit der Option 'average=day' werden alle numerischen Werte eines Tages auf einen einzigen
Mittelwert reduziert (impliziert 'average'). <br><br>
Mit den Attributen "device" und "reading" können die zu berücksichtigenden Datensätze eingeschlossen
bzw. ausgeschlossen werden. Beide Eingrenzungen reduzieren die selektierten Daten und verringern den
Ressourcenbedarf.
Das Reading "reduceLogState" enthält das Ausführungsergebnis des letzten reduceLog-Befehls. <br><br>
Die für diese Funktion relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>executeBeforeProc</b> </td><td>: FHEM Kommando (oder perl-Routine) vor dem Export ausführen </td></tr>
<tr><td> <b>executeAfterProc</b> </td><td>: FHEM Kommando (oder perl-Routine) nach dem Export ausführen </td></tr>
<tr><td> <b>device</b> </td><td>: einschließen oder ausschließen von Datensätzen die &lt;device&gt; enthalten </td></tr>

</table>
</ul>
<br>
Aus Kompatibilitätsgründen kann der Befehl optional durch die Zusätze "EXCLUDE" bzw. "INCLUDE"
ergänzt werden um device/reading Kombinationen von reduceLog auszuschließen bzw. einzuschließen: <br><br>
<ul>
"reduceLog [average[=day]] [EXCLUDE=device1:reading1,device2:reading2,...] [INCLUDE=device:reading]" <br><br>
</ul>
Diese Angabe wird als Regex ausgewertet und überschreibt die Attribute "device" und "reading",
die in diesem Fall nicht beachtet werden. <br><br>
<ul>
<b>Beispiele: </b><br><br>
attr &lt;name&gt; timeOlderThan = d:200 <br>
set &lt;name&gt; reduceLog <br>
# Datensätze die älter als 200 Tage sind, werden auf den ersten Eintrag pro Stunde je Device & Reading
reduziert. <br>
<br>
attr &lt;name&gt; timeDiffToNow = d:200 <br>
set &lt;name&gt; reduceLog average=day <br>
# Datensätze die neuer als 200 Tage sind, werden auf einen Eintrag pro Tag je Device & Reading
reduziert. <br>
<br>
attr &lt;name&gt; timeDiffToNow = d:30 <br>
attr &lt;name&gt; device = TYPE=SONOSPLAYER EXCLUDE=Sonos_Kueche <br>
attr &lt;name&gt; reading = room% EXCLUDE=roomNameAlias <br>
set &lt;name&gt; reduceLog <br>
# Datensätze die neuer als 30 Tage sind, die Devices vom Typ SONOSPLAYER sind
(außer Device "Sonos_Kueche"), die Readings mit "room" beginnen (außer "roomNameAlias"),
werden auf den ersten Eintrag pro Stunde je Device & Reading reduziert. <br>
<br>
attr &lt;name&gt; timeDiffToNow = d:10 <br>
attr &lt;name&gt; timeOlderThan = d:5 <br>
attr &lt;name&gt; device = Luftdaten_remote <br>
set &lt;name&gt; reduceLog average <br>
# Datensätze die älter als 5 und neuer als 10 Tage sind und DEVICE "Luftdaten_remote" enthalten,
werden bereinigt. Numerische Werte einer Stunde werden auf einen Mittelwert reduziert <br>
<br>
</ul>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, sollte das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden
(Tabellen-Lock). <br>
Weiterhin wird dringend empfohlen den standard INDEX 'Search_Idx' in der Tabelle 'history'
anzulegen ! <br>
Die Abarbeitung dieses Befehls dauert unter Umständen (ohne INDEX) extrem lange. <br><br>
</li> <br>
<li><b> repairSQLite </b> - repariert eine korrupte SQLite-Datenbank. <br>
Eine Korruption liegt im Allgemeinen vor wenn die Fehlermitteilung "database disk image is malformed"
im state des DbLog-Devices erscheint.
Wird dieses Kommando gestartet, wird das angeschlossene DbLog-Device zunächst automatisch für 10 Stunden
(36000 Sekunden) von der Datenbank getrennt (Trennungszeit). Nach Abschluss der Reparatur erfolgt
wieder eine sofortige Neuverbindung zur reparierten Datenbank. <br>
Dem Befehl kann eine abweichende Trennungszeit (in Sekunden) als Argument angegeben werden. <br>
Die korrupte Datenbank wird als &lt;database&gt;.corrupt im gleichen Verzeichnis gespeichert. <br><br>
<ul>
<b>Beispiel: </b><br>
set &lt;name&gt; repairSQLite <br>
# Die Datenbank wird repariert, Trennungszeit beträgt 10 Stunden <br>
set &lt;name&gt; repairSQLite 600 <br>
# Die Datenbank wird repariert, Trennungszeit beträgt 10 Minuten
<br><br>
<b>Hinweis:</b> <br>
Es ist nicht garantiert, dass die Reparatur erfolgreich verläuft und keine Daten verloren gehen.
Je nach Schwere der Korruption kann Datenverlust auftreten oder die Reparatur scheitern, auch wenn
kein Fehler im Ablauf signalisiert wird. Ein Backup der Datenbank sollte unbedingt vorhanden
sein ! <br><br>
</li> <br>
</ul>
<li><b> restoreMySQL &lt;File&gt; </b> - stellt die Datenbank aus einem serverSide- oder clientSide-Dump wieder her. <br>
Die Funktion stellt über eine Drop-Down Liste eine Dateiauswahl für den Restore zur Verfügung. <br><br>
<b>Verwendung eines serverSide-Dumps </b> <br>
Es wird der Inhalt der history-Tabelle aus einem serverSide-Dump wiederhergestellt.
Dazu ist das Verzeichnis "dumpDirRemote" des MySQL-Servers auf dem Client zu mounten
und im <a href="#DbRepattr">Attribut</a> "dumpDirLocal" dem DbRep-Device bekannt zu machen. <br>
Es werden alle Files mit der Endung "csv[.gzip]" und deren Name mit der
verbundenen Datenbank beginnt (siehe Internal DATABASE), aufgelistet.
<br><br>
<b>Verwendung eines clientSide-Dumps </b> <br>
Es werden alle Tabellen und eventuell vorhandenen Views wiederhergestellt.
Das Verzeichnis, in dem sich die Dump-Files befinden, ist im <a href="#DbRepattr">Attribut</a> "dumpDirLocal" dem
DbRep-Device bekannt zu machen. <br>
Es werden alle Files mit der Endung "sql[.gzip]" und deren Name mit der
verbundenen Datenbank beginnt (siehe Internal DATABASE), aufgelistet. <br>
Die Geschwindigkeit des Restores ist abhängig von der Servervariable "<b>max_allowed_packet</b>". Durch Veränderung
dieser Variable im File my.cnf kann die Geschwindigkeit angepasst werden. Auf genügend verfügbare Ressourcen (insbesondere
RAM) ist dabei zu achten. <br><br>
Der Datenbankuser benötigt Rechte zum Tabellenmanagement, z.B.: <br>
CREATE, ALTER, INDEX, DROP, SHOW VIEW, CREATE VIEW
<br><br>
</li><br>
<li><b> restoreSQLite &lt;File&gt;.sqlitebkp[.gzip] </b> - stellt das Backup einer SQLite-Datenbank wieder her. <br>
Die Funktion stellt über eine Drop-Down Liste die für den Restore zur Verfügung stehenden Dateien
zur Verfügung. Die aktuell in der Zieldatenbank enthaltenen Daten werden gelöscht bzw.
überschrieben.
Es werden alle Files mit der Endung "sqlitebkp[.gzip]" und deren Name mit dem Namen der
verbundenen Datenbank beginnt, aufgelistet . <br><br>
</li><br>
<li><b> sqlCmd </b> - führt ein beliebiges benutzerspezifisches Kommando aus. <br>
Enthält dieses Kommando eine Delete-Operation, muss zur Sicherheit das
<a href="#DbRepattr">Attribut</a> "allowDeletion" gesetzt sein. <br>
Bei der Ausführung dieses Kommandos werden keine Einschränkungen durch gesetzte Attribute
"device", "reading", "time.*" bzw. "aggregation" berücksichtigt. <br>
Dieses Kommando akzeptiert ebenfalls das Setzen von SQL Session Variablen wie z.B.
"SET @open:=NULL, @closed:=NULL;". <br>
Sollen die im Modul gesetzten <a href="#DbRepattr">Attribute</a> "timestamp_begin" bzw.
"timestamp_end" im Statement berücksichtigt werden, können die Platzhalter
"<b>§timestamp_begin§</b>" bzw. "<b>§timestamp_end§</b>" dafür verwendet werden. <br><br>
Soll ein Datensatz upgedated werden, ist dem Statement "TIMESTAMP=TIMESTAMP" hinzuzufügen um eine Änderung des
originalen Timestamps zu verhindern. <br><br>
<ul>
<b>Beispiele für Statements: </b> <br><br>
<ul>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= "2017-01-06 00:00:00" group by DEVICE having count(*) > 800 </li>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= "2017-05-06 00:00:00" group by DEVICE </li>
<li>set &lt;name&gt; sqlCmd select DEVICE, count(*) from history where TIMESTAMP >= §timestamp_begin§ group by DEVICE </li>
<li>set &lt;name&gt; sqlCmd select * from history where DEVICE like "Te%t" order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select * from history where `TIMESTAMP` > "2017-05-09 18:03:00" order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select * from current order by `TIMESTAMP` desc </li>
<li>set &lt;name&gt; sqlCmd select sum(VALUE) as 'Einspeisung am 04.05.2017', count(*) as 'Anzahl' FROM history where `READING` = "Einspeisung_WirkP_Zaehler_Diff" and TIMESTAMP between '2017-05-04' AND '2017-05-05' </li>
<li>set &lt;name&gt; sqlCmd delete from current </li>
<li>set &lt;name&gt; sqlCmd delete from history where TIMESTAMP < "2016-05-06 00:00:00" </li>
<li>set &lt;name&gt; sqlCmd update history set TIMESTAMP=TIMESTAMP,VALUE='Val' WHERE VALUE='TestValue' </li>
<li>set &lt;name&gt; sqlCmd select * from history where DEVICE = "Test" </li>
<li>set &lt;name&gt; sqlCmd insert into history (TIMESTAMP, DEVICE, TYPE, EVENT, READING, VALUE, UNIT) VALUES ('2017-05-09 17:00:14','Test','manuell','manuell','Tes§e','TestValue','°C') </li>
</ul>
<br>
Nachfolgend noch ein Beispiel für ein komplexeres Statement (MySQL) unter Mitgabe von
SQL Session Variablen: <br><br>
<ul>
<li>set &lt;name&gt; sqlCmd SET @open:=NULL, @closed:=NULL;
SELECT
TIMESTAMP, VALUE,DEVICE,
@open AS open,
@open := IF(VALUE = 'open', TIMESTAMP, NULL) AS curr_open,
@closed := IF(VALUE = 'closed', TIMESTAMP, NULL) AS closed
FROM history WHERE
DATE(TIMESTAMP) = CURDATE() AND
DEVICE = "HT_Fensterkontakt" AND
READING = "state" AND
(VALUE = "open" OR VALUE = "closed")
ORDER BY TIMESTAMP; </li>
</ul>
<br>
Das Ergebnis des Statements wird im <a href="#DbRepReadings">Reading</a> "SqlResult" dargestellt.
Die Ergebnis-Formatierung kann durch das <a href="#DbRepattr">Attribut</a> "sqlResultFormat" ausgewählt, sowie der verwendete
Feldtrenner durch das <a href="#DbRepattr">Attribut</a> "sqlResultFieldSep" festgelegt werden. <br><br>
Das Modul stellt optional eine Kommando-Historie zur Verfügung sobald ein SQL-Kommando erfolgreich
ausgeführt wurde.
Um diese Option zu nutzen, ist das Attribut "sqlCmdHistoryLength" mit der gewünschten Listenlänge
zu aktivieren. <br><br>
Zur besseren Übersicht sind die zur Steuerung von sqlCmd relevanten Attribute hier noch einmal
dargestellt: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>allowDeletion</b> </td><td>: aktiviert Löschmöglichkeit </td></tr>
<tr><td> <b>sqlResultFormat</b> </td><td>: legt die Darstellung des Kommandoergebnis fest </td></tr>
<tr><td> <b>sqlResultFieldSep</b> </td><td>: Auswahl Feldtrenner im Ergebnis </td></tr>
<tr><td> <b>sqlCmdHistoryLength</b> </td><td>: Aktivierung Kommando-Historie und deren Umfang</td></tr>
</table>
</ul>
<br>
<br>
<b>Hinweis:</b> <br>
Auch wenn das Modul bezüglich der Datenbankabfrage nichtblockierend arbeitet, kann eine
zu große Ergebnismenge (Anzahl Zeilen bzw. Readings) die Browsersesssion bzw. FHEMWEB
blockieren. Wenn man sich unsicher ist, sollte man vorsorglich dem Statement ein Limit
hinzufügen. <br><br>
</li> <br>
</ul>
<li><b> sqlCmdHistory </b> - Wenn mit dem <a href="#DbRepattr">Attribut</a> "sqlCmdHistoryLength" aktiviert, kann
aus einer Liste ein bereits erfolgreich ausgeführtes sqlCmd-Kommando wiederholt werden. <br>
Mit Ausführung des letzten Eintrags der Liste, "__purge_historylist__", kann die Liste gelöscht
werden. <br>
Falls das Statement "," enthält, wird dieses Zeichen aus technischen Gründen in der
History-Liste als "&lt;c&gt;" dargestellt. <br>
</li><br>
<li><b> sqlSpecial </b> - Die Funktion bietet eine Drop-Downliste mit einer Auswahl vorbereiter Auswertungen
an. <br>
Das Ergebnis des Statements wird im Reading "SqlResult" dargestellt.
Die Ergebnis-Formatierung kann durch das <a href="#DbRepattr">Attribut</a> "sqlResultFormat"

<li><b> sumValue [display | writeToDB]</b>
- Berechnet die Summenwerte des Datenbankfelds "VALUE" in den Zeitgrenzen
(Attribute) "timestamp_begin", "timestamp_end" bzw. "timeDiffToNow / timeOlderThan".
Es muss das auszuwertende Reading im <a href="#DbRepattr">Attribut</a> "reading"
angegeben sein. Diese Funktion ist sinnvoll wenn fortlaufend Wertedifferenzen eines
Readings in die Datenbank geschrieben werden. <br>
Ist keine oder die Option "display" angegeben, werden die Ergebnisse nur angezeigt. Mit
der Option "writeToDB" werden die Berechnungsergebnisse mit einem neuen Readingnamen
in der Datenbank gespeichert. <br>
Der neue Readingname wird aus einem Präfix und dem originalen Readingnamen gebildet,
wobei der originale Readingname durch das Attribut "readingNameMap" ersetzt werden kann.
Der Präfix setzt sich aus der Bildungsfunktion und der Aggregation zusammen. <br>
Der Timestamp der neuen Readings in der Datenbank wird von der eingestellten Aggregationsperiode
abgeleitet, sofern kein eindeutiger Zeitpunkt des Ergebnisses bestimmt werden kann.
Das Feld "EVENT" wird mit "calculated" gefüllt.<br><br>

<li><b> syncStandby &lt;DbLog-Device Standby&gt; </b>
- Es werden die Datensätze aus der angeschlossenen Datenbank (Quelle) direkt in eine weitere
Datenbank (Standby-Datenbank) übertragen.
Dabei ist "&lt;DbLog-Device Standby&gt;" das DbLog-Device, welches mit der Standby-Datenbank
verbunden ist. <br><br>
Es werden alle Datensätze übertragen, die durch Timestamp-<a href="#limit">Attribute</a>

Quell- und Standby-Datenbank können unterschiedlichen Typs sein.
<br><br>
Die zur Steuerung der syncStandby Funktion relevanten Attribute sind: <br><br>
<ul>
<table>
<colgroup> <col width=5%> <col width=95%> </colgroup>
<tr><td> <b>aggregation</b> </td><td>: Einstellung der Zeitscheiben zur Übertragung (hour,day,week) </td></tr>
<tr><td> <b>device</b> </td><td>: einschließen oder ausschließen von Datensätzen die &lt;device&gt; enthalten </td></tr>
<tr><td> <b>reading</b> </td><td>: einschließen oder ausschließen von Datensätzen die &lt;reading&gt; enthalten </td></tr>
<tr><td> <b>time.*</b> </td><td>: Attribute zur Zeitabgrenzung der zu übertragenden Datensätze. </td></tr>
<tr><td style="vertical-align:top"> <b>valueFilter</b> <td>: ein zusätzliches REGEXP um die Datenselektion zu steuern. Der REGEXP wird auf das Datenbankfeld 'VALUE' angewendet. </td></tr>
</table>
</ul>
<br>
</li> <br>
<li><b> tableCurrentFillup </b> - Die current-Tabelle wird mit einem Extrakt der history-Tabelle aufgefüllt.
Die <a href="#DbRepattr">Attribute</a> zur Zeiteinschränkung bzw. device, reading werden ausgewertet.
Dadurch kann der Inhalt des Extrakts beeinflusst werden. Im zugehörigen DbLog-Device sollte sollte das Attribut
"DbLogType=SampleFill/History" gesetzt sein. </li> <br>
<li><b> tableCurrentPurge </b> - löscht den Inhalt der current-Tabelle. Es werden keine Limitierungen, z.B. durch die Attribute "timestamp_begin",
"timestamp_end", device, reading, usw. , ausgewertet. </li> <br>
<li><b> vacuum </b> - optimiert die Tabellen in der angeschlossenen Datenbank (SQLite, PostgreSQL). <br>
Vor und nach der Optimierung kann ein FHEM-Kommando ausgeführt werden.
(siehe <a href="#DbRepattr">Attribute</a> "executeBeforeProc", "executeAfterProc")
<br><br>
<ul>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, muß das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEM zu vermeiden. <br><br>
</li>
</ul><br>
<br>
</ul></ul>
<b>Für alle Auswertungsvarianten (Ausnahme sqlCmd,deviceRename,readingRename) gilt: </b> <br>
Zusätzlich zu dem auszuwertenden Reading kann das Device mit angegeben werden um das Reporting nach diesen Kriterien einzuschränken.
Sind keine Zeitgrenzen-Attribute angegeben jedoch das Aggregations-Attribut gesetzt, wird der Zeitstempel des ältesten
Datensatzes in der Datenbank als Startdatum und das aktuelle Datum/die aktuelle Zeit als Zeitgrenze genutzt.
Konnte der älteste Datensatz in der Datenbank nicht ermittelt werden, wird '1970-01-01 01:00:00' als Selektionsstart
genutzt (siehe get &lt;name&gt; minTimestamp).
Sind weder Zeitgrenzen-Attribute noch Aggregation angegeben, wird die Datenselektion ohne Timestamp-Einschränkungen
ausgeführt.
<br><br>
<b>Hinweis: </b> <br>
In der Detailansicht kann ein Browserrefresh nötig sein um die Operationsergebnisse zu sehen sobald im DeviceOverview "state = done" angezeigt wird.
<br><br>
</ul>
<a name="DbRepget"></a>
<b>Get </b>
<ul>
Die Get-Kommandos von DbRep dienen dazu eine Reihe von Metadaten der verwendeten Datenbankinstanz abzufragen.
Dies sind zum Beispiel eingestellte Serverparameter, Servervariablen, Datenbankstatus- und Tabelleninformationen. Die verfügbaren get-Funktionen
sind von dem verwendeten Datenbanktyp abhängig. So ist für SQLite z.Zt. nur "svrinfo" verfügbar. Die Funktionen liefern nativ sehr viele Ausgabewerte,
die über über funktionsspezifische <a href="#DbRepattr">Attribute</a> abgrenzbar sind. Der Filter ist als kommaseparierte Liste anzuwenden.
Dabei kann SQL-Wildcard (%) verwendet werden.
<br><br>
<b>Hinweis: </b> <br>
Nach der Ausführung einer get-Funktion in der Detailsicht einen Browserrefresh durchführen um die Ergebnisse zu sehen !
<br><br>
<ul><ul>
<li><b> blockinginfo </b> - Listet die aktuell systemweit laufenden Hintergrundprozesse (BlockingCalls) mit ihren Informationen auf.
Zu lange Zeichenketten (z.B. Argumente) werden gekürzt ausgeschrieben.
</li>
<br><br>
<li><b> dbstatus </b> - Listet globale Informationen zum MySQL Serverstatus (z.B. Informationen zum Cache, Threads, Bufferpools, etc. ).
Es werden zunächst alle verfügbaren Informationen berichtet. Mit dem <a href="#DbRepattr">Attribut</a> "showStatus" kann die
Ergebnismenge eingeschränkt werden, um nur gewünschte Ergebnisse abzurufen. Detailinformationen zur Bedeutung der einzelnen Readings
sind <a href=http://dev.mysql.com/doc/refman/5.7/en/server-status-variables.html>hier</a> verfügbar. <br>
<br><ul>
<b>Bespiel</b> <br>
get &lt;name&gt; dbstatus <br>
attr &lt;name&gt; showStatus %uptime%,%qcache% <br>
# Es werden nur Readings erzeugt die im Namen "uptime" und "qcache" enthalten
</li>
<br><br>
</ul>
<li><b> dbValue &lt;SQL-Statement&gt;</b> -
Führt das angegebene SQL-Statement <b>blockierend</b> aus. Diese Funktion ist durch ihre Arbeitsweise
speziell für den Einsatz in benutzerspezifischen Scripten geeignet. <br>
Die Eingabe akzeptiert Mehrzeiler und gibt ebenso mehrzeilige Ergebisse zurück.
Dieses Kommando akzeptiert ebenfalls das Setzen von SQL Session Variablen wie z.B.
"SET @open:=NULL, @closed:=NULL;". <br>
Werden mehrere Felder selektiert und zurückgegeben, erfolgt die Feldtrennung mit dem Trenner
des <a href="#DbRepattr">Attributes</a> "sqlResultFieldSep" (default "|"). Mehrere Ergebniszeilen
werden mit Newline ("\n") separiert. <br>
Diese Funktion setzt/aktualisiert nur Statusreadings, die Funktion im Attribut "userExitFn"
wird nicht aufgerufen.
<br>
<br><ul>
<b>Bespiele zur Nutzung im FHEMWEB</b> <br>
{fhem("get &lt;name&gt; dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device")} <br>
get &lt;name&gt; dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device <br>
{CommandGet(undef,"Rep.LogDB1 dbValue select device,count(*) from history where timestamp > '2018-04-01' group by device")} <br>
</ul>
<br><br>
Erstellt man eine kleine Routine in 99_myUtils, wie z.B.:
<br>
<pre>
sub dbval($$) {
my ($name,$cmd) = @_;
my $ret = CommandGet(undef,"$name dbValue $cmd");
return $ret;
}
</pre>
kann dbValue vereinfacht verwendet werden mit Aufrufen wie:
<br><br>
<ul>
<b>Bespiele</b> <br>
{dbval("&lt;name&gt;","select count(*) from history")} <br>
oder <br>
$ret = dbval("&lt;name&gt;","select count(*) from history"); <br>
</ul>
</li>
<br><br>
<li><b> dbvars </b> - Zeigt die globalen Werte der MySQL Systemvariablen. Enthalten sind zum Beispiel Angaben zum InnoDB-Home, dem Datafile-Pfad,
Memory- und Cache-Parameter, usw. Die Ausgabe listet zunächst alle verfügbaren Informationen auf. Mit dem
<a href="#DbRepattr">Attribut</a> "showVariables" kann die Ergebnismenge eingeschränkt werden um nur gewünschte Ergebnisse
abzurufen. Weitere Informationen zur Bedeutung der ausgegebenen Variablen sind
<a href=http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html>hier</a> verfügbar. <br>
<br><ul>
<b>Bespiel</b> <br>

# Es werden nur Readings erzeugt die im Namen "version" und "query_cache" enthalten
</li>
<br><br>
</ul>
<li><b> minTimestamp </b> - Ermittelt den Zeitstempel des ältesten Datensatzes in der Datenbank (wird implizit beim Start von
FHEM ausgeführt).
Der Zeitstempel wird als Selektionsbeginn verwendet wenn kein Zeitattribut den Selektionsbeginn
festlegt.
</li>
<br><br>
<li><b> procinfo </b> - Listet die existierenden Datenbank-Prozesse in einer Tabelle auf (nur MySQL). <br>
Typischerweise werden nur die Prozesse des Verbindungsusers (angegeben in DbLog-Konfiguration)
ausgegeben. Sollen alle Prozesse angezeigt werden, ist dem User das globale Recht "PROCESS"
einzuräumen. <br>
Für bestimmte SQL-Statements wird seit MariaDB 5.3 ein Fortschrittsreporting (Spalte "PROGRESS")
ausgegeben. Zum Beispiel kann der Abarbeitungsgrad bei der Indexerstellung verfolgt werden. <br>

</li>
<br><br>
<li><b> svrinfo </b> - allgemeine Datenbankserver-Informationen wie z.B. die DBMS-Version, Serveradresse und Port usw. Die Menge der Listenelemente
ist vom Datenbanktyp abhängig. Mit dem <a href="#DbRepattr">Attribut</a> "showSvrInfo" kann die Ergebnismenge eingeschränkt werden.

</li>
<br><br>
</ul>
<li><b> tableinfo </b> - ruft Tabelleninformationen aus der mit dem DbRep-Device verbundenen Datenbank ab (MySQL).
Es werden per default alle in der verbundenen Datenbank angelegten Tabellen ausgewertet.
Mit dem <a href="#DbRepattr">Attribut</a> "showTableInfo" können die Ergebnisse eingeschränkt werden. Erläuterungen zu den erzeugten

</li>
<br><br>
</ul>
<li><b> versionNotes [hints | rel | &lt;key&gt;] </b> -
Zeigt Release Informationen und/oder Hinweise zum Modul an. Es sind nur Release Informationen mit
Bedeutung für den Modulnutzer enthalten. <br>
Sind keine Optionen angegben, werden sowohl Release Informationen als auch Hinweise angezeigt.
"rel" zeigt nur Release Informationen und "hints" nur Hinweise an. Mit der &lt;key&gt;-Angabe
wird der Hinweis mit der angegebenen Nummer angezeigt.
</li>
<br>
</ul></ul>
</ul>
<a name="DbRepattr"></a>
<b>Attribute</b>
<br>
<ul>
Über die modulspezifischen Attribute wird die Abgrenzung der Auswertung und die Aggregation der Werte gesteuert. <br>
Die hier aufgeführten Attribute sind nicht für jede Funktion des Moduls bedeutsam. In der Hilfe zu den set/get-Kommandos
wird explizit angegeben, welche Attribute für das jeweilige Kommando relevant sind. <br><br>
<b>Hinweis zur SQL-Wildcard Verwendung:</b> <br>
Innerhalb der Attribut-Werte für "device" und "reading" kann SQL-Wildcards "%" angegeben werden.
Dabei wird "%" als Platzhalter für beliebig viele Zeichen verwendet.
Das Zeichen "_" wird nicht als SQL-Wildcard supported. <br>
Dies gilt für alle Funktionen <b>ausser</b> "insert", "importFromFile" und "deviceRename". <br>
Die Funktion "insert" erlaubt nicht, dass die genannten Attribute das Wildcard "%" enthalten. Character "_" wird als normales Zeichen gewertet.<br>
In Ergebnis-Readings wird das Wildcardzeichen "%" durch "/" ersetzt um die Regeln für erlaubte Zeichen in Readings einzuhalten.
<br><br>
<ul><ul>
<a name="aggregation"></a>
<li><b>aggregation </b> - Zusammenfassung der Device/Reading-Selektionen in Stunden,Tage,Kalenderwochen,Kalendermonaten
oder "no". <br>
Liefert z.B. die Anzahl der DB-Einträge am Tag (countEntries), Summierung von
Differenzwerten eines Readings (sumValue), usw. <br>
Mit Aggregation "no" (default) erfolgt keine Zusammenfassung in einem Zeitraum, sondern die
Ausgabe wird aus allen Werten einer Device/Reading-Kombination zwischen den definierten
Zeiträumen ermittelt. </li> <br>
<a name="allowDeletion"></a>
<li><b>allowDeletion </b> - schaltet die Löschfunktion des Moduls frei </li> <br>
<a name="averageCalcForm"></a>
<li><b>averageCalcForm </b> - legt die Berechnungsvariante für die Ermittlung des Durchschnittswertes mit "averageValue"
fest.
<br><br>
Zur Zeit sind folgende Varianten implementiert: <br><br>
<ul>
<table>
<colgroup> <col width=20%> <col width=80%> </colgroup>
<tr><td> <b>avgArithmeticMean :</b> </td><td>es wird der arithmetische Mittelwert berechnet (default) </td></tr>
<tr><td style="vertical-align:top"> <b>avgDailyMeanGWS :</b> <td>berechnet die Tagesmitteltemperatur entsprechend den
Vorschriften des deutschen Wetterdienstes (siehe "get &lt;name&gt; versionNotes 2"). <br>
Diese Variante verwendet automatisch die Aggregation "day". </td></tr>
<tr><td> <b>avgTimeWeightMean :</b> </td><td>berechnet den zeitgewichteten Mittelwert </td></tr>
</table>
</ul>
</li><br>
<a name="countEntriesDetail"></a>
<li><b>countEntriesDetail </b> - Wenn gesetzt, erstellt die Funktion "countEntries" eine detallierte Ausgabe der Datensatzzahl
pro Reading und Zeitintervall.
Standardmäßig wird nur die Summe aller selektierten Datensätze ausgegeben.
</li> <br>
<a name="device"></a>
<li><b>device </b> - Abgrenzung der DB-Selektionen auf ein bestimmtes oder mehrere Devices. <br>
Es können Geräte-Spezifikationen (devspec) angegeben werden. <br>
Innerhalb von Geräte-Spezifikationen wird SQL-Wildcard (%) als normales ASCII-Zeichen gewertet.
Die Devicenamen werden vor der Selektion aus der Geräte-Spezifikationen und den aktuell in FHEM
vorhandenen Devices abgeleitet. <br>
Wird dem Device bzw. der Device-Liste oder Geräte-Spezifikation ein "EXCLUDE=" vorangestellt,
werden diese Devices von der Selektion ausgeschlossen.
<br><br>
<ul>
<b>Beispiele:</b> <br>
<code>attr &lt;name&gt; device TYPE=DbRep </code> <br>
<code>attr &lt;name&gt; device MySTP_5000 </code> <br>
<code>attr &lt;name&gt; device SMA.*,MySTP.* </code> <br>
<code>attr &lt;name&gt; device SMA_Energymeter,MySTP_5000 </code> <br>
<code>attr &lt;name&gt; device %5000 </code> <br>
<code>attr &lt;name&gt; device TYPE=SSCam EXCLUDE=SDS1_SVS </code> <br>
<code>attr &lt;name&gt; device EXCLUDE=SDS1_SVS </code> <br>
<code>attr &lt;name&gt; device EXCLUDE=TYPE=SSCam </code> <br>
</ul>
<br>
Falls weitere Informationen zu Geräte-Spezifikationen benötigt werden, bitte
"get &lt;name&gt; versionNotes 3" ausführen.
<br><br>
</li>
<a name="diffAccept"></a>
<li><b>diffAccept </b> - gilt für Funktion diffValue. diffAccept legt fest bis zu welchem Schwellenwert eine berechnete positive Werte-Differenz
zwischen zwei unmittelbar aufeinander folgenden Datensätzen akzeptiert werden soll (Standard ist 20). <br>
Damit werden fehlerhafte DB-Einträge mit einem unverhältnismäßig hohen Differenzwert von der Berechnung ausgeschlossen und
verfälschen nicht das Ergebnis. Sollten Schwellenwertüberschreitungen vorkommen, wird das Reading "diff_overrun_limit_&lt;diffLimit&gt;"
erstellt. (&lt;diffLimit&gt; wird dabei durch den aktuellen Attributwert ersetzt)
Es enthält eine Liste der relevanten Wertepaare. Mit verbose 3 werden diese Datensätze ebenfalls im Logfile protokolliert.
<br><br>
<ul>
Beispiel Ausgabe im Logfile beim Überschreiten von diffAccept=10: <br><br>
DbRep Rep.STP5000.etotal -> data ignored while calc diffValue due to threshold overrun (diffAccept = 10): <br>
2016-04-09 08:50:50 0.0340 -> 2016-04-09 12:42:01 13.3440 <br><br>
# Der erste Datensatz mit einem Wert von 0.0340 ist untypisch gering zum nächsten Wert 13.3440 und führt zu einem zu hohen
Differenzwert. <br>
# Es ist zu entscheiden ob der Datensatz gelöscht, ignoriert, oder das Attribut diffAccept angepasst werden sollte.
</ul><br>
</li>

Zur POSIX Wildcardverwendung siehe auch die Erläuterungen zu <a href="#FileLog">Filelog</a>.
<br><br>
</li>
<a name="fastStart"></a>
<li><b>fastStart </b> - Normalerweise verbindet sich jedes DbRep-Device beim FHEM-Start kurz mit seiner Datenbank um
benötigte Informationen abzurufen und das Reading "state" springt bei Erfolg auf "connected".
Ist dieses Attribut gesetzt, erfolgt die initiale Datenbankverbindung erst dann wenn das
DbRep-Device sein erstes Kommando ausführt. <br>
Das Reading "state" verbleibt nach FHEM-Start solange im Status "initialized". Diese Einstellung
kann hilfreich sein wenn viele DbRep-Devices definiert sind.
</li> <br>
<a name="fetchMarkDuplicates"></a>
<li><b>fetchMarkDuplicates </b>
- Markierung von mehrfach vorkommenden Datensätzen im Ergebnis des "fetchrows" Kommandos </li> <br>

<li><b>fetchRoute [descent | ascent] </b> - bestimmt die Leserichtung des fetchrows-Befehl. <br><br>
<ul>
<b>descent</b> - die Datensätze werden absteigend gelesen (default). Wird
die durch das Attribut "limit" festgelegte Anzahl der Datensätze
überschritten, werden die neuesten x Datensätze angezeigt. <br><br>
<b>ascent</b> - die Datensätze werden aufsteigend gelesen. Wird
die durch das Attribut "limit" festgelegte Anzahl der Datensätze
überschritten, werden die ältesten x Datensätze angezeigt. <br>
</ul>
</li> <br><br>
<a name="ftpUse"></a>
<li><b>ftpUse </b> - FTP Transfer nach einem Dump wird eingeschaltet (ohne SSL Verschlüsselung). Das erzeugte
Datenbank Backupfile wird non-blocking zum angegebenen FTP-Server (Attribut "ftpServer")
übertragen. </li> <br>
<a name="ftpUseSSL"></a>
<li><b>ftpUseSSL </b> - FTP Transfer mit SSL Verschlüsselung nach einem Dump wird eingeschaltet. Das erzeugte
Datenbank Backupfile wird non-blocking zum angegebenen FTP-Server (Attribut "ftpServer")
übertragen. </li> <br>

<a name="limit"></a>
<li><b>limit </b> - begrenzt die Anzahl der resultierenden Datensätze im select-Statement von "fetchrows", bzw. der anzuzeigenden Datensätze
der Kommandos "delSeqDoublets adviceDelete", "delSeqDoublets adviceRemain" (default 1000).
Diese Limitierung soll eine Überlastung der Browsersession und ein
blockieren von FHEMWEB verhindern. Bei Bedarf entsprechend ändern bzw. die
Selektionskriterien (Zeitraum der Auswertung) anpassen. </li> <br>
<a name="optimizeTablesBeforeDump"></a>
<li><b>optimizeTablesBeforeDump </b> - wenn "1", wird vor dem Datenbankdump eine Tabellenoptimierung ausgeführt (default: 0).
Dadurch verlängert sich die Laufzeit des Dump. <br><br>
<ul>

</ul>
</li> <br>
<a name="reading"></a>
<li><b>reading </b> - Abgrenzung der DB-Selektionen auf ein bestimmtes oder mehrere Readings sowie exkludieren von

</li> <br>
<a name="seqDoubletsVariance"></a>
<li><b>seqDoubletsVariance </b> - akzeptierte Abweichung (+/-) für das Kommando "set &lt;name&gt; delSeqDoublets". <br>
Der Wert des Attributs beschreibt die Abweichung bis zu der aufeinanderfolgende numerische
Werte (VALUE) von Datensätze als gleich angesehen und gelöscht werden sollen.
"seqDoubletsVariance" ist ein absoluter Zahlenwert,
der sowohl als positive als auch negative Abweichung verwendet wird.
<br><br>
<ul>
<b>Beispiele:</b> <br>

<br><br>
<ul>
<b>Bespiel: </b> <br>
attr &lt;name&gt; showSvrInfo %SQL_CATALOG_TERM%,%NAME% <br>
# Es werden nur Readings erzeugt die im Namen "SQL_CATALOG_TERM" und "NAME" enthalten <br>
</ul><br>
</li>
<a name="showTableInfo"></a>
<li><b>showTableInfo </b> - grenzt die Ergebnismenge des Befehls "get &lt;name&gt; tableinfo" ein. Es können
SQL-Wildcard (%) verwendet werden.

"set ... sqlCmd" fest. </li> <br>
<a name="sqlCmdHistoryLength"></a>
<li><b>sqlCmdHistoryLength </b>
- aktiviert die Kommandohistorie von "sqlCmd" und legt deren Länge fest </li> <br>
<a name="sqlResultFormat"></a>
<li><b>sqlResultFormat </b> - legt die Formatierung des Ergebnisses des Kommandos "set &lt;name&gt; sqlCmd" fest.
Mögliche Optionen sind: <br><br>
<ul>

SqlResult dargestellt. Satztrenner ist"]|[". <br><br>
<b>table </b> - das Ergebnis wird als Tabelle im Reading
SqlResult dargestellt. <br><br>
<b>json </b> - erzeugt das Reading SqlResult als
JSON-kodierten Hash.
Jedes Hash-Element (Ergebnissatz) setzt sich aus der laufenden Nummer
des Datensatzes (Key) und dessen Wert zusammen. <br><br>
Die Weiterverarbeitung des Ergebnisses kann z.B. mit der folgenden userExitFn in 99_myUtils.pm erfolgen: <br>
<pre>
sub resfromjson {

</pre>
</ul><br>
</li>
<a name="timeYearPeriod"></a>
<li><b>timeYearPeriod </b> - Mit Hilfe dieses Attributes wird eine jährliche Zeitperiode für die Datenbankselektion bestimmt.
Die Zeitgrenzen werden zur Ausführungszeit dynamisch berechnet. Es wird immer eine Jahresperiode
bestimmt. Eine unterjährige Angabe ist nicht möglich. <br>
Dieses Attribut ist vor allem dazu gedacht Auswertungen synchron zu einer Abrechnungsperiode, z.B. der eines
Energie- oder Gaslieferanten, anzufertigen.
<br><br>
<ul>
<b>Beispiel:</b> <br><br>
attr &lt;name&gt; timeYearPeriod 06-25 06-24 <br><br>
# wertet die Datenbank in den Zeitgrenzen 25. Juni AAAA bis 24. Juni BBBB aus. <br>
# Das Jahr AAAA bzw. BBBB wird in Abhängigkeit des aktuellen Datums errechnet. <br>
# Ist das aktuelle Datum >= 25. Juni und =< 31. Dezember, dann ist AAAA = aktuelles Jahr und BBBB = aktuelles Jahr+1 <br>
# Ist das aktuelle Datum >= 01. Januar und =< 24. Juni, dann ist AAAA = aktuelles Jahr-1 und BBBB = aktuelles Jahr
</ul>
<br><br>
</li>
<a name="timestamp_begin"></a>
<li><b>timestamp_begin </b> - der zeitliche Beginn für die Datenselektion <br>

<a name="timestamp_end"></a>
<li><b>timestamp_end </b> - das zeitliche Ende für die Datenselektion. Wenn nicht gesetzt wird immer die aktuelle
Datum/Zeit-Kombi für das Ende der Selektion eingesetzt. <br>
Das Format von Timestamp ist "YYYY-MM-DD HH:MM:SS". Für die Attribute "timestamp_begin", "timestamp_end"
kann ebenso eine der folgenden Eingaben verwendet werden. Dabei wird das timestamp-Attribut dynamisch belegt: <br><br>
<ul>

</ul><br>
Natürlich sollte man immer darauf achten dass "timestamp_begin" < "timestamp_end" ist. <br><br>
<ul>
<b>Beispiel:</b> <br><br>
attr &lt;name&gt; timestamp_begin current_year_begin <br>
attr &lt;name&gt; timestamp_end current_year_end <br><br>
# Wertet die Datenbank in den Zeitgrenzen des aktuellen Jahres aus. <br>
</ul>
<br>
<b>Hinweis </b> <br>
Wird das Attribut "timeDiffToNow" gesetzt, werden die eventuell gesetzten anderen Zeit-Attribute
("timestamp_begin","timestamp_end","timeYearPeriod") gelöscht.
Das Setzen von "timestamp_begin" bzw. "timestamp_end" bedingt die Löschung von anderen Zeit-Attribute falls sie vorher
gesetzt waren.
<br><br>
</li>
<a name="timeDiffToNow"></a>
<li><b>timeDiffToNow </b> - der <b>Selektionsbeginn</b> wird auf den Zeitpunkt <b>"&lt;aktuelle Zeit&gt; - &lt;timeDiffToNow&gt;"</b>
gesetzt (z.b. werden die letzten 24 Stunden in die Selektion eingehen wenn das Attribut auf "86400" gesetzt
wurde). Die Timestampermittlung erfolgt dynamisch zum Ausführungszeitpunkt.
<br><br>
<ul>
<b>Eingabeformat Beispiel:</b> <br>
<code>attr &lt;name&gt; timeDiffToNow 86400</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 86400 Sekunden" gesetzt <br>
<code>attr &lt;name&gt; timeDiffToNow d:2 h:3 m:2 s:10</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 2 Tage 3 Stunden 2 Minuten 10 Sekunden" gesetzt <br>
<code>attr &lt;name&gt; timeDiffToNow m:600</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 600 Minuten" gesetzt <br>
<code>attr &lt;name&gt; timeDiffToNow h:2.5</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 2,5 Stunden" gesetzt <br>
<code>attr &lt;name&gt; timeDiffToNow y:1 h:2.5</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 1 Jahr und 2,5 Stunden" gesetzt <br>
<code>attr &lt;name&gt; timeDiffToNow y:1.5</code> <br>
# die Startzeit wird auf "aktuelle Zeit - 1,5 Jahre gesetzt <br>
</ul>
<br>
Sind die Attribute "timeDiffToNow" und "timeOlderThan" gleichzeitig gesetzt, wird der
Selektionszeitraum zwischen diesen Zeitpunkten dynamisch kalkuliert.
<br><br>
</li>
<a name="timeOlderThan"></a>
<li><b>timeOlderThan </b> - das <b>Selektionsende</b> wird auf den Zeitpunkt <b>"&lt;aktuelle Zeit&gt; - &lt;timeOlderThan&gt;"</b>
gesetzt. Dadurch werden alle Datensätze bis zu dem Zeitpunkt "&lt;aktuelle
Zeit&gt; - &lt;timeOlderThan&gt;" berücksichtigt (z.b. wenn auf 86400 gesetzt, werden alle
Datensätze die älter als ein Tag sind berücksichtigt). Die Timestampermittlung erfolgt
dynamisch zum Ausführungszeitpunkt.
<br><br>
<ul>
<b>Eingabeformat Beispiel:</b> <br>
<code>attr &lt;name&gt; timeOlderThan 86400</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 86400 Sekunden" gesetzt <br>
<code>attr &lt;name&gt; timeOlderThan d:2 h:3 m:2 s:10</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 2 Tage 3 Stunden 2 Minuten 10 Sekunden" gesetzt <br>
<code>attr &lt;name&gt; timeOlderThan m:600</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 600 Minuten" gesetzt <br>
<code>attr &lt;name&gt; timeOlderThan h:2.5</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 2,5 Stunden" gesetzt <br>
<code>attr &lt;name&gt; timeOlderThan y:1 h:2.5</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 1 Jahr und 2,5 Stunden" gesetzt <br>
<code>attr &lt;name&gt; timeOlderThan y:1.5</code> <br>
# das Selektionsende wird auf "aktuelle Zeit - 1,5 Jahre gesetzt <br>
</ul>
<br>
Sind die Attribute "timeDiffToNow" und "timeOlderThan" gleichzeitig gesetzt, wird der
Selektionszeitraum zwischen diesen Zeitpunkten dynamisch kalkuliert.
<br><br>
</li>
<a name="timeout"></a>
<li><b>timeout </b> - das Attribut setzt den Timeout-Wert für die Blocking-Call Routinen in Sekunden
(Default: 86400) </li> <br>
<a name="userExitFn"></a>
<li><b>userExitFn </b> - stellt eine Schnittstelle zur Ausführung eigenen Usercodes zur Verfügung. <br>
Um die Schnittstelle zu aktivieren, wird zunächst die aufzurufende Subroutine in
99_myUtls.pm nach folgendem Muster erstellt: <br>
<pre>
sub UserFunction {
my ($name,$reading,$value) = @_;
my $hash = $defs{$name};
...
# z.B. übergebene Daten loggen
Log3 $name, 1, "UserExitFn $name called - transfer parameter are Reading: $reading, Value: $value " ;
...
return;
}
</pre>
Die Aktivierung der Schnittstelle erfogt durch Setzen des Funktionsnamens im Attribut.
Optional kann ein Reading:Value Regex als Argument angegeben werden. Wird kein Regex
angegeben, werden alle Wertekombinationen als "wahr" gewertet (entspricht .*:.*).
<br><br>
<ul>
<b>Beispiel:</b> <br>
attr <device> userExitFn UserFunction .*:.* <br>
# "UserFunction" ist die Subroutine in 99_myUtils.pm.
</ul>
<br>
Grundsätzlich arbeitet die Schnittstelle OHNE Eventgenerierung bzw. benötigt zur Funktion keinen
Event. Sofern das Attribut gesetzt ist, erfolgt Die Regexprüfung NACH der Erstellung eines
Readings. Ist die Prüfung WAHR, wird die angegebene Funktion aufgerufen.
Zur Weiterverarbeitung werden der aufgerufenenen Funktion folgende Variablen übergeben: <br><br>
<ul>
<li>$name - der Name des DbRep-Devices </li>
<li>$reading - der Namen des erstellen Readings </li>
<li>$value - der Wert des Readings </li>
</ul>
</li>
<br>
<br>
<a name="valueFilter"></a>
<li><b>valueFilter </b> - Regulärer Ausdruck (REGEXP) zur Filterung von Datensätzen innerhalb bestimmter Funktionen.
Der REGEXP wird auf ein bestimmtes Feld oder den gesamten selektierten Datensatz (inkl. Device,
Reading usw.) angewendet.
Bitte beachten sie die Erläuterungen zu den entsprechenden Set-Kommandos. Weitere Informationen
sind mit "get &lt;name&gt; versionNotes 4" verfügbar. </li> <br>
</ul></ul>
</ul>
<a name="DbRepReadings"></a>
<b>Readings</b>
<br>
<ul>
Abhängig von der ausgeführten DB-Operation werden die Ergebnisse in entsprechenden Readings dargestellt. Zu Beginn einer neuen Operation
werden alle alten Readings einer vorangegangenen Operation gelöscht um den Verbleib unpassender bzw. ungültiger Readings zu vermeiden.
<br><br>
Zusätzlich werden folgende Readings erzeugt (Auswahl): <br><br>
<ul><ul>
<li><b>state </b> - enthält den aktuellen Status der Auswertung. Wenn Warnungen auftraten (state = Warning) vergleiche Readings
"diff_overrun_limit_&lt;diffLimit&gt;" und "less_data_in_period" </li> <br>
<li><b>errortext </b> - Grund eines Fehlerstatus </li> <br>
<li><b>background_processing_time </b> - die gesamte Prozesszeit die im Hintergrund/Blockingcall verbraucht wird </li> <br>
<li><b>diff_overrun_limit_&lt;diffLimit&gt;</b> - enthält eine Liste der Wertepaare die eine durch das Attribut "diffAccept" festgelegte Differenz
&lt;diffLimit&gt; (Standard: 20) überschreiten. Gilt für Funktion "diffValue". </li> <br>
<li><b>less_data_in_period </b> - enthält eine Liste der Zeitperioden in denen nur ein einziger Datensatz gefunden wurde. Die
Differenzberechnung berücksichtigt den letzten Wert der Vorperiode. Gilt für Funktion "diffValue". </li> <br>
<li><b>sql_processing_time </b> - der Anteil der Prozesszeit die für alle SQL-Statements der ausgeführten
Operation verbraucht wird </li> <br>
<li><b>SqlResult </b> - Ergebnis des letzten sqlCmd-Kommandos. Die Formatierung erfolgt entsprechend
des <a href="#DbRepattr">Attributes</a> "sqlResultFormat" </li> <br>
<li><b>sqlCmd </b> - das letzte ausgeführte sqlCmd-Kommando </li> <br>
</ul></ul>
<br>
</ul>
<a name="DbRepAutoRename"></a>
<b>DbRep Agent - automatisches Ändern von Device-Namen in Datenbanken und DbRep-Definitionen nach FHEM "rename" Kommando</b>
<br>
<ul>
Mit dem Attribut "role" wird die Rolle des DbRep-Device festgelegt. Die Standardrolle ist "Client". Mit der Änderung der Rolle in "Agent" wird das Device
veranlasst auf Umbenennungen von Geräten in der FHEM Installation zu reagieren. <br><br>
Durch den DbRep-Agenten werden folgende Features aktiviert wenn ein Gerät in FHEM mit "rename" umbenannt wird: <br><br>
<ul><ul>
<li> in der dem DbRep-Agenten zugeordneten Datenbank (Internal Database) wird nach Datensätzen mit dem alten Gerätenamen gesucht und dieser Gerätename in
<b>allen</b> betroffenen Datensätzen in den neuen Namen geändert. </li> <br>
<li> in dem DbRep-Agenten zugeordneten DbLog-Device wird in der Definition das alte durch das umbenannte Device ersetzt. Dadurch erfolgt ein weiteres Logging
des umbenannten Device in der Datenbank. </li> <br>
<li> in den existierenden DbRep-Definitionen vom Typ "Client" wird ein evtl. gesetztes Attribut "device = alter Devicename" in "device = neuer Devicename"
geändert. Dadurch werden Auswertungsdefinitionen bei Geräteumbenennungen automatisch konstistent gehalten. </li> <br>
</ul></ul>
Mit der Änderung in einen Agenten sind folgende Restriktionen verbunden die mit dem Setzen des Attributes "role = Agent" eingeschaltet
und geprüft werden: <br><br>
<ul><ul>
<li> es kann nur einen Agenten pro Datenbank in der FHEM-Installation geben. Ist mehr als eine Datenbank mit DbLog definiert, können
ebenso viele DbRep-Agenten eingerichtet werden </li> <br>
<li> mit der Umwandlung in einen Agenten wird nur noch das Set-Komando "renameDevice" verfügbar sein sowie nur ein eingeschränkter Satz von DbRep-spezifischen
Attributen zugelassen. Wird ein DbRep-Device vom bisherigen Typ "Client" in einen Agenten geändert, werden evtl. gesetzte und nun nicht mehr zugelassene
Attribute glöscht. </li> <br>
</ul></ul>
Die Aktivitäten wie Datenbankänderungen bzw. Änderungen an anderen DbRep-Definitionen werden im Logfile mit verbose=3 protokolliert. Damit die renameDevice-Funktion
bei großen Datenbanken nicht in ein timeout läuft, sollte das Attribut "timeout" entsprechend dimensioniert werden. Wie alle Datenbankoperationen des Moduls
wird auch das Autorename nonblocking ausgeführt. <br><br>
<ul>
<b>Beispiel </b> für die Definition eines DbRep-Device als Agent: <br><br>
<code>
define Rep.Agent DbRep LogDB <br>
attr Rep.Agent devStateIcon connected:10px-kreis-gelb .*disconnect:10px-kreis-rot .*done:10px-kreis-gruen <br>
attr Rep.Agent icon security <br>
attr Rep.Agent role Agent <br>
attr Rep.Agent room DbLog <br>
attr Rep.Agent showproctime 1 <br>
attr Rep.Agent stateFormat { ReadingsVal("$name","state", undef) eq "running" ? "renaming" : ReadingsVal("$name","state", undef). " &raquo;; ProcTime: ".ReadingsVal("$name","sql_processing_time", undef)." sec"} <br>
attr Rep.Agent timeout 86400 <br>
</code>
<br>
</ul>
<b>Hinweis:</b> <br>
Obwohl die Funktion selbst non-blocking ausgelegt ist, sollte das zugeordnete DbLog-Device
im asynchronen Modus betrieben werden um ein Blockieren von FHEMWEB zu vermeiden (Tabellen-Lock). <br><br>
