monit error “alert handler failed…”

If you get a message like this in your monit log files:

alert handler failed, retry scheduled for next cycle

It’s not immediately obvious what’s causing it. Check the line before, it’s probably what you’re looking for.

In my case I was getting this error

Sendmail error: 553 5.1.7 [email protected]… address incomplete

Which is actually from the mailserver I’d setup in the monitrc file. Make sure you’ve got your settings right, and don’t just look at the one line 🙂
