I think we might have answered part of the processor_performance question.... If you do something like this: ``` windows_cpu_core_frequency_mhz{} * (rate(windows_cpu_processor_performance{}[2m])) / ON (core) (1 - sum by (core) (rate(windows_cpu_cstate_seconds_total{}[2m])))...

Hi @carlpett, Sorry for the huge delay in following up on this - it's been a busy year. I revisited this issue recently because some BIOS tuning failed to apply...

Of course, I start testing this on some actually loaded production systems and the got complete nonsense back. I investigated some more, and I'm pretty sure that `RawValue` is an...

Hi @breed808 - I've made a rough version of the proposed changes here: https://github.com/prometheus-community/windows_exporter/compare/master...higels:windows_exporter:add_mperf_metric and to perflib_exporter here: https://github.com/leoluk/perflib_exporter/compare/master...higels:perflib_exporter:add_secondvalue_plumbing Basic summary is that we add a `SecondValue` member to `perflib.PerfCounter`,...

I've been running an exporter based on my changes above for a day now on quite a large number of systems, and I have CPU metrics that very accurately match...

I will hopefully have time to get my changes rebased and submitted this week. Thanks all for your work on this!

Yes, it is possible for the utilization number to go over 100%. I *swear* I had documentation for `% Processor Utility` counter under Processor Information stating this, but I can't...

Ah, I see what you are saying - I was referring to a separate issue. I do also see this issue with our own fleet, but I'm rarely zooming in...

Yes, the value should be constant, so I don't think it would affect alert latency.
