Hello Nagios Support,
We tried setting up a perfmon Cache Hit Rate command check in XI to monitor a Windows 2012 Server.
The command is this:
check_xi_service_nsclient!COUNTER!-l "\\HTTP Service Request
Queues(ptw1.aetna.com)\\CacheHitRate","Cache Hit Rate is %.f " -w 40 -c 60

When we apply the service to the host the metric always comes back as : Cache Hit
Rate is 0.

We also added the Perfmon data collector set in Windows for HTTP Service Requests/CacheHit per this article: https://technet.microsoft.com/en-us/lib ... s.11).aspx
Any ideas why it doesn't gather the metrics from Windows?

Thanks.

If you look at the counter in the perfmon application on the same server does it come back with a value > 0?

It looks like it does yes.

Question:
Does the data collector set have to be started in order for Nagios to capture the data?
Or is this something that Nagios will automatically gather?

The counters displayed are RejectionRate, what if you add to the view and ONLY choose

Ok , I tried to add/view only CacheHitRate for all instances and shows 0
Do you know how this should be set up for Nagios to fetch this data?

Thanks again.

I think you have it setup correctly above, it's just that the value is 0 for this counter and that is what Nagios is retrieving.

Ok thank you Scott.
I appreciate the feedback.

Let us know if you have other issues.
