Processor Counter Monitor: missing and non working performance counters

gveld — Thu, 08 Feb 2018 22:47:52 GMT

I've managed to get the Processor Counter Monitor to work as a windows service.
This adds extra performance counters which can be read from the windows tool perfmon or with external monitoring tools.

Unfortunately a lot of these performance counters are not working correctly. The following performance counters always report 0:
\PCM Core Counters(*)\L2 Cache Misses
\PCM Core Counters(*)\L3 Cache Misses
\PCM QPI Counters(*)\QPI Link Bandwidth
\PCM Socket Counters(*)\Memory Read Bandwidth
\PCM Socket Counters(*)\Memory Write Bandwidth

Another issue I have is that not all information from the PCM.exe tool is available as a performance counter. The following metrics are missing:
L3HIT
L2HIT
L3MPI
L2MPI

And the actual CPU usage calculations are also missing:
PHYSICAL CORE IPC : 0.83 => corresponds to 20.77 % utilization for cores in active state
Instructions per nominal CPU cycle: 0.68 => corresponds to 16.97 % core utilization over time interval

Update: I've noticed that the L2 and L3 Cache Misses are working, but only if the PCM.exe tool is running.
Seems like PCM-service isn't properly retrieving most metrics from the CPU by itself..
