Hello,
if the process is monitored by monit as well, clean configuration may look like
this:
--8<--
check process myprocess with pidfile ...
start program = "/etc/init.d/my_service start"
stop program = "/etc/init.d/my_service stop"
restart program = "/etc/init.d/my_service restart"
check file myfile with path ...
if matched "FOOBAR" then exec "/usr/bin/monit restart myprocess"
--8<--
The "PID changed" event is triggered if the monitored process was restarted out
of monit control - in this case the start/stop script was executed via exec
action which has no relationship with the process check itself (monit doesn't
analyze the exec action command), hence it seemed the process was restarted
externally. Using "monit restart myprocess" is clear request to restart the
process. Monit doesn't support actions with references to other services, so
the workaround is to use the exec action.
The restart problem itself may be related to monit < 5.9 on some platforms ...
the Monit 5.9 and newer should work fine.
Regards,
Martin
