[mythtv-users] Status check/monitoring of mythbackend

[Henrik Ostergaard Madsen]

My monit-conf for monitoring myth-backend is:

check process mythbackend with pidfile /var/run/mythtv/mythbackend.pid 
every 3 cycles
   start program = "/etc/init.d/mythtv-backend start"
   stop program = "/etc/init.d/mythtv-backend stop"
   if failed host Mythserver port 6543 3 times within 10 cycles then restart
   if 5 restarts within 15 cycles then timeout                                     


This has been working fine for half a year. It has to incorporate a delay 
before restarting it, as it can be rather long to startup after a restart.

And my startupscript in /etc/init.d is:
