# Simple watchdog solution to monitor and restart fhem on Linux.

# Add this define to the fhem configuration:
# define at_FhemPulse at +*00:10 {system("/bin/date +%s > /opt/fhem/log/fhem_pulse.log")}
#
# Add a cron job that runs every ten minutes -> crontab -e
# */10 * * * * /opt/fhem/contrib/fhem_watchdog.sh
LOGFILE="/opt/fhem/log/fhem_pulse.log"
if [ `systemctl status fhem|grep inactive|wc -l` -eq "0" ]; then
# fhem service was started
if [ ! -e "${LOGFILE}" ]; then
# There is no pulse log file
systemctl restart fhem
exit 0
fi
if [ $(expr $(/bin/date +%s) - $(cat ${LOGFILE})) -gt 900 ]; then
# Last pulse is older than 15min.
systemctl restart fhem
