Another option might be to use the 'cron' format to tell it not to
monitor during just that window. We do this during the final part of our
db backup process when it requires a lock for a minute or so to finalize.
check program db-status with path /usr/local/bin/check_status with
timeout 15 seconds
not every "50-55 0 * * *"
if status != 0 then alert

Have you considered adjusting how often monit checks and set your cron
job for log rotate to run in between? E.g. run monit every 5 seconds
and have your log rotate happen on second 2. The PID would change, but
shouldn't throw an alert.

Hello,
So we should also concluded there is currently no way to
delayed/avoid the first alerts and that the only possibility is to
"unmonitor" which can cause issues and is against goal of Monit ?
Explanation: if we "unmonitor" the check (sometime process,
sometime program) and an issue prevent the script in charge of
"monitoring" again to successfully finished, the service will be
down and we won't get alerted as it is "unmonitored".
In fact "Log Rotation" was only one simple possible restart cause,
but we have lots of custom scripts also for our custom tools like
"restart if some conditions are met" with help of monit process
exit code.
Maybe a workaround would be to cut the action script in several
part so that even if the restart is failing, the monitoring is
still issued.
Another workaround would be to check the status of the "monit
check" and if this status is "unmonitor" for several cycles, force
"monitoring" again in order to be notified that something bad happens.
What is your point of view about these ?
Best Regards.

Hello,
monit tests if the process is running - it cannot
differentiate that the process was stopped intentionally by
3rd party action ... if you shutdown the process intentionally
during logrotate, you should disable its monitoring first
(part of logratotation "prerotate" script):
monit unmonitor myprocess
and when logratotation finished, enable it again (part of
logratotation "postrotate" script):
monit monitor myprocess

Martin
