Re: monit check that a process does NOT exist

[Martin Pala]

It is possible (using the "else if succeeded then ..." part:

if does not exist then alert else if succeeded then exec "/usr/local/monit-scripts/ruby-daemon.sh push_notification stop"

Monit is however design to keep the process running, so if the process will be online on Monit start, the action won't be executed, as it must fail first in order to allow the fail->success transition.

It could be thus better to use "check program" with simple pgrep based script, more details about the "check program": http://www.mmonit.com/monit/documentation/monit.html#PROGRAM-STATUS-TESTING

Thanks Martin,

I'm trying to achieve the opposite.

If the process exists I need to stop it.

Is that possible?

Thanks,

Phil

Hi,

the correct syntax is:

        if DOES NOT exist then exec "/usr/local/monit-scripts/ruby-daemon.sh push_notification stop"
