Issue:

Submission Queue Length monitor in exchange_monitor probe is unable to retrieve the correct counter from Windows Performance Counters.

We can see in Exchange 'Get-Queue' command that the Submission queue is not zero. The same can be seen via Windows Perfmon > MSExchangeTransport Queues > Submission Queue Length > _total, which reports the correct number.

When we check the perfmon and exchange_monitor probes it is always reporting 0 messages in the queue.

Environment:
UIM 8.51exchange_monitor 5.32perfmon 1.63
Cause:

This is caused by an issue in the exchange_monitor probe configuration file.

Resolution:

To resolve this problem please deactivate the exchange_monitor probe and perform the following steps:

1- take a backup of the exchange_monitor.cfg file

2- edit this file and find the 'Submission Queue Length' section

3- change the following item from/to:

from

x_instance = _Total

to

instance = _total

4- start the exchange_monitor probe and check the results
