<h3>Log2Syslog</h3>
|

<ul>
|
||||
Send FHEM system log entries and/or FHEM events to an external syslog server. <br><br>
|
||||
|
||||
<b>Prerequisits</b>
|
||||
<ul>
|
||||
<br/>
|
||||
The additional perl module "IO::Socket::INET" must be installed on your system. <br>
|
||||
Install this package from cpan or by <br><br>
|
||||
|
||||
<code>apt-get install libio-socket-multicast-perl (only on Debian based installations) </code><br>
|
||||
</ul>
|
||||
<br>
|
||||
|
||||
<a name="Log2Syslogdefine"></a>
|
||||
<b>Define</b>
|
||||
<ul>
|
||||
<br>
|
||||
<code>define <name> Log2Syslog <destination host> [event:<regexp>] [fhem:<regexp>]</code><br>
|
||||
<br>
|
||||
|
||||
<destination host> = host where the syslog server is running <br>
|
||||
[event:<regexp>] = optional regex to filter events for logging <br>
|
||||
[fhem:<regexp>] = optional regex to filter fhem system log for logging <br><br>
|
||||
|
||||
After definition the new device sends all new appearing fhem systemlog entries and events to the destination host,
|
||||
port=514/UDP format:IETF, immediately without further settings if the regex for fhem or event were set. <br>
|
||||
Without setting regex no fhem system log or event log will be forwarded. <br>
|
||||
The module uses functions of Perls SYS::SYSLOG module. If you want know more, see for detailed descriptions
|
||||
on <a href="http://perldoc.perl.org/Sys/Syslog.html">perldoc</a>. <br>
|
||||
|
||||
<br>
|
||||
Example to log anything: <br>
|
||||
<br/>
|
||||
<code>define splunklog Log2Syslog fhemtest 192.168.2.49 event:.* fhem:.* </code><br>
|
||||
<br/>
|
||||
will produce output like:<br/>
|
||||
<pre>Mar 20 15:25:22 fhem-vm-8 fhem: global: SAVE
|
||||
Mar 20 15:25:44 fhem-vm-8 fhem: global: SHUTDOWN

<li><code>addTimestamp [0|1]</code><br>

<br/>
|

If set to 1, fhem timestamps will be logged too.<br/>
|

Default behavior is to not log these timestamps, because syslog uses own timestamps.<br/>
|
||||
Maybe useful if mseclog is activated in fhem.<br/>

<h3>Log2Syslog</h3>
|
||||
<ul>
|
||||
Sendet FHEM Systemlog Einträge und/oder Events an einen externen Syslog-Server weiter. <br/>
|
||||
<br/>
|
||||
|
||||
<b>Voraussetzungen</b>
|
||||
<ul>
|
||||
<br/>
|
||||
Es wird das Perl Modul "IO::Socket::INET" benötigt und muss installiert sein. <br>
|
||||
Das Modul kann über CPAN oder mit <br><br>
|
||||
|
||||
<code>apt-get install libio-socket-multicast-perl (auf Debian Linux Systemen) </code><br><br>
|
||||
|
||||
installiert werden.
|
||||
</ul>
|
||||

|
||||
|
||||
<a name="Log2Syslogdefine"></a>
|
||||
<b>Definition</b>
|
||||
<ul>
|
||||
<br>
|
||||
<code>define <name> Log2Syslog <destination host> [event:<regexp>] [fhem:<regexp>] </code><br>
|
||||
<br>
|
||||
|
||||
<Zielhost> = Host (Name oder IP-Adresse) auf dem der Syslog-Server läuft <br>
|
||||
[event:<regexp>] = optionaler regulärer Ausdruck zur Filterung von Events zur Weiterleitung <br>
|
||||
[fhem:<regexp>] = optionaler regulärer Ausdruck zur Filterung von FHEM Logs zur Weiterleitung <br><br>
|
||||
|
||||
Direkt nach der Definition sendet das neue Device alle neu auftretenden FHEM Systemlog Einträge und Events ohne weitere
|
||||
Einstellungen an den Zielhost, Port=514/UDP Format:IETF, wenn reguläre Ausdrücke für Events/FHEM angegeben wurden. <br>
|
||||
Wurde kein Regex gesetzt, erfolgt keine Weiterleitung von Events oder FHEM Systemlogs. <br>
|
||||
Das Modul verwendet Funktionen des Perl-Moduls SYS::SYSLOG. Weitere Informationen dazu sind auf
|
||||
<a href="http://perldoc.perl.org/Sys/Syslog.html">perldoc</a> zu finden. <br>
|
||||
|
||||
<br>
|
||||
Beispiel:<br/>
|
||||
<br/>
|
||||
<code>define splunklog Log2Syslog fhemtest 192.168.2.49 </code><br/>
|
||||
<br/>
|
||||
Es werden alle Events weitergeleitet:<br/>

<a name="addTimestamp"></a>
|

<li><code>addTimestamp [0|1]</code><br>
|

<br/>
|

Wenn gesetzt, werden FHEM Timestamps im Datensatz mit übertragen.<br/>
|

Per default werden die Timestamps nicht mit übertragen, da der Syslog-Server eigene Timestamps verwendet.<br/>
|

Die Einstellung kann hilfeich sein wenn mseclog in FHEM aktiviert ist.<br/>
