I am monitoring few Perfromance Counters using the Microsoft Zenpack. Its working as expected but for few perfromance counters I can see below error in logs.

2015-08-31 19:03:36,539 WARNING zen.windows: 25 missing counters for sharepoint.itistolab.com - see debug for details

But when i do perform on the windows server and check the performance of these counters it exists and has value in it. Please let me know if I am missing something

Hi Gowrish, I also helped Tim answer this on your Zendesk ticket, but it would be good to have this information here as well.

The reason you are seeing missing counters is because you are specifying wildcards in the counter name, which will return the counters for all processes, disks, network interfaces, etc. The way that the Windows Perfmon datasource works is that we are looking for exact names for the counters.

So, when you try to get the counter "\physicaldisk(*)\current disk queue length", what is returned from Windows will be something like this: "\physicaldisk(0 c: q:)\current disk queue length", etc. But, there is no counter returned with the name "\physicaldisk(*)\current disk queue length".

In most instances, you can use a TALES evaluation to pull in the id of the component that you are monitoring, ${here/id}.

We are already polling some of these counters. For instance we are looking at the "working set" of a process. See the wiki on how to monitor a process.

Thanks
Dave
