Re: Check the age of a process

Yes, the uptime test can be used this way.

The process check will however alert if the process is not running - you can suppress this alert though: https://mmonit.com/monit/documentation/monit.html#Setting-an-event-filter

What if I wanted to check for something running too long?  I tried this and it's alerting for not being present or for having less uptime.  Is it possible to negate the alerting logic so it's OK when something is not running or it's less that a certain age?

check process filter_grep_age matching filter_grep

    if uptime > 7 hours then alert

This filter_grep command shouldn't run for more than a few hours or a user has forgotten to stop it.

Hello Dave,
a process uptime test ist available, see
https://mmonit.com/monit/documentation/monit.html#UPTIME-TEST

The uptime test is availabel for the process and system service
definitions only.

With regards,
Lutz

p.s.
The test is available since some years (I find the test in Monit 5.16).
Check the used Monit version with the command "monit -V".
