The new check plugin zertificon_mail_queues monitors the mail queue lengths of Zertificon mail encryption appliances via SNMP. The following seven queues are monitored (OIDs .1.3.6.1.4.1.2021.8.1.100.{5-10, 17}):

  • Total Postfix queue
  • Incoming queue
  • Active queue
  • Deferred queue
  • Hold queue
  • Maildrop queue
  • Z1 Messenger queue

The check goes WARN / CRIT if the length of any of these queues exceeds configurable levels. Per default, there are no upper levels.

This plugin is only available as an enforced service to avoid discovering this service for non-Zertificon devices. This is necessary because Zertificon appliances cannot be decisively identified based on their SNMP data.
