Overview

This article describes the issue when you are unable to view performance counters within SAM showing as unknown/unavailable.

Environment

All versions of SAM

 

Cause 

According to Microsoft, "This can occur if the counter has been disabled intentionally, or if the counter has been disabled by the operating system itself due to it faulting 3 times"

 

Resolution

Follow the steps indicated in this TechNet Article: http://blogs.technet.com/b/askperf/archive/2010/03/05/two-minute-drill-disabled-performance-counters-and-exctrlst-exe.aspx.

 

There is a tool available within this webpage called Exctrlst.exe, which shows a list if installed perf counters, and whether they are enabled or disabled. You can utilize this tool to determine if the component monitor in question is disabled
