Postfix: Mailqueue Length

Included in	All Checkmk editions
Source Code License	Open Source
Supported Agents	Linux

This check monitors the number of deferred mails in the outgoing mail queue, as sent by the linux agent of Checkmk. Depending on the version of the Checkmk agent the number of mails in the active queue is monitored as well.

This check creates one service per host which represents the state of the mailqueues.

The check will result in WARNING/CRITICAL states when the number of items in the queues have reached the defined thresholds.

Name of the Postfix queue

Discovery

One service is created on each system which provides the postconf. If postconf is not installed, we fall back to ssmtp. On FreeBSD systems, if both postconf and ssmtp are not installed, we check the DragonFly Mail Agent (dma) instead.
