Re: Q: Arbitrary program status for process check?

[Noel]

You have it backwards.  check_xyzzy depends on xyzzy.

First run the process, then run the script to see if the process is working.

Hi Viktor,

Thank you for your examples. You have a very complex monit configuration, and I can learn a lot.

However, I tried the "depends" implementation, but it did not work when trying to start the service.

If my "xyzzy" service depends on "check_xyzzy" then it will not be able to start, because before xyzzy is able to start. monit wants check_xyzzy to work, but check_xyzzy doesn't succeed, because xyzzy isn't running. It is a "chicken and egg" problem.

Hello Steven!

I use tiny script with "depends on"
https://github.com/szepeviktor/debian-server-tools/blob/master/monitoring/monit/services/fail2ban_script
to check on services
