Monit - how to check loadavg only when no backup is running?

Question

I've got Monit configuration with:

check system example.com
    if loadavg (1min) > 4 then alert
    if loadavg (5min) > 2 then alert

I want to get rid of messages every time backup is running at night, but I do not want to turn it off completely.

How to add check for gzip/bzip2 process runing like:

`ps aux | grep '\[gb\]zip'`

or disable that one check at some time?

Answer 1

You can tell Monit to stop monitoring during certain times (ie while your backup is running). It uses the same syntax as cron. There are good examples in Monit Documentation in the Service Poll Times section. You probably want something like:

check system example.com
not every "* 2-4 * * *"

This will stop monitoring every night from 2am-4am

Answer 2

You should "unmonitor" the system load check during the backup interval.

monit unmonitor example.com

You can do this for a specific duration with an at script or just cron, if you know your backup window time.

Resume the monitoring after the backup window:

monit monitor example.com

Answer 3

Stop monit when run backup.

Like:

  ==backup.sh==
  /usr/local/etc/rc.d/monit stop
  ...do backup...
  /usr/local/etc/rc.d/monit start
