Check manual page of winperf_msx_queues
Length of MS Exchange queues
This check monitors the current length of various MS Exchange
mail queues. You need a Windows agent of version 1.1.11i1 or
later and have the counter object msx_queues activated.
This counter is activated per default with the number 10332.
If the counter number is different in your installation or
you are using a check_mk.ini with custom counter definitions,
add the counter to the section [winperf] with counters = 10332:msx_queues ... .
Look in the output of lodctr /s:counters.ini for the object with
the name MSExchangeTransport Queues.
You can set levels for warning and critical. Per default
the queues Active Remote Delivery, Active Mailbox Delivery,
Retry Remote Delivery and Poison are monitored.
The name of the queue as defined in winperf_msx_queues.
For each queue that is defined in winperf_msx_queues one check
will be created if the agent outputs the matching performance counters.
