Nagios Support Forum

Hi all,
according to this article: https://docs.microsoft.com/en-us/exchan ... -2013-help
I want to monitor Exchange performance counters but i have some issues:

Example 1:
Memory\Available Mbytes Performance Counter

Example 1 works correctly:
On my Exchange server from Powershell get-counters "\Memory\Available Mbytes" is OK
On my Nagios server check_nt -H xxx -p xxx-s xxx -v COUNTER -l "\\Memory\Available Mbytes" same OK

Example 2:
MSExchange Database ==> Instances(*)\I/O Database Reads (Attached) Average Latency

In this case from PowerShell I receive the value but from Nagios no:
NSClient - ERROR: No performance data from command: check_pdh

This happens with a lot of counters and seems that is relative to the specific counters of Exchange.
How I can provide to solve that?
Thanks

It might be worthwhile visiting these performance counter articles as they get into the specifics about how to reference the counters, sometimes escaping special characters is required.
