System Processor Queue Length Windows Server 2012 R2

Microsoft.Windows.Server.2012.R2.OperatingSystem.SystemProcessorQueueLength.Collection (Rule)

Collection rule for the performance counter System\Processor Queue Length.

Knowledge Base article:

Summary

This rule collects performance data for the System\ Processor Queue Length performance counter.

The System\Processor Queue Length performance counter exposes the number of threads in the processor queue. Unlike the disk counters, this counter counters, this counter shows ready threads only, not threads that are running. There is a single queue for processor time even on computers with multiple processors. Therefore, if a computer has multiple processors, you need to divide this value by the number of processors servicing the workload. A sustained processor queue of less than 10 threads per processor is normally acceptable, dependent of the workload.
