Re: How to monitor service start/restart/stop?

[Martin Pala]

Monit 4.3 will send NONEXIST event in the case that the process is not 
running - as soon as the process will start again, you will receive 
recovery notification. You can use exec to involve your logger as you 
noted. Monit always reports the triggered action (e.g. 'restart', 
'alert', etc.) In the case that the service is under monit's control 
(i.e. monit is responsible for service starting/stopping), it  will work 
well. If monit is not responsible for starting/stopping (i.e. external 
process/user is responsible for that), then you risk race conditions 
given by testing cycle length.

You can add also the call to your logger directly to start/stop program 
script related to monitored service. Monit provides another information 
in environment variables to to the executed program.
