Length of the postfix mailqueues

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check monitors the number of deferred mails in the outgoing mail queue, as sent by the linux agent of Check_MK. Depending on the version of the Check_MK 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.


On each system which provides the postconf command one service is created.
