Monitor Dovecot with Munin on OpenBSD


At the time of writing, Munin on OpenBSD doesn’t come with a dovecot dedicated plugin. I’m not sure it even comes with an IMAP plugin. Anyway, you can get one from the “Munin plugin repository” and run it on your BSD box. Here’s how:

Monitoring with M/Monit on OpenBSD

Note that my box is both a client and a server regarding monitoring events.

Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.” I like it because it is much lighter than Nagios. In the OpenBSD ports, it is available in version 4. But it is also provided as a binary archive from the website. Here’s how to run Monit v5 on OpenBSD.
