How can i send daily alerts for linux server monitoring using Monit tool(free edition)?

Question

I am using monit free edition to monitor server status, but in that the alerts works only when some triggering action done. However, I want to send a daily alert of all the details of server as monit shows.

Answer 1

What are you trying to do ? Some kind of "reporting" ?

Monit is not able to do this. As you said, Monit sends an alert when a service check is triggered. This is by design.

I would suggest to setup a daily cron job that will run a Bash script of your own.

Your script could parse Monit log file, retrieve events for the given day, organize informations for a more user-friendly reading and send the report.

However, if you don't want to use Cron but still use Monit, you could use the service poll time feature from Monit.

The idea here, is to trigger a fake service check, once a day, that will also run a Bash script of your own, to perform the same things as described above for the cron job.

The fake service definition could look like this :

check process fake with pidfile /var/run/fake.pid
  start program = "/root/report.sh"
  stop program = "/root/report.sh"
  every "00 23 * * 0-6"

This will be triggered every day at 11 PM.

But, in my opinion, this solution is not the most suitable because :

• you will have "wrong" alerts in your Monit log file
• this could be triggered more than once if you have setup Monit deamon polling interval less than one minute (e.g. 30 seconds).
