Example for realtime sampling of "\\Processor(*)\\% processor time"?

[jjYBdx4IL]

Can you please give an example on how to do this?

 string[] arr = new string[1];
 arr[0] = "\\Processor(*)\\% processor time";
 PerfCounterRealTimeProbe pcrtp = new PerfCounterRealTimeProbe(this, TimeSpan.FromSeconds(1), arr);

However, that causes a PDH_CSTATUS_NO_OBJECT exception.

your code looks good. Maybe the issue is lowercase letters in "processor time" Tx does not do any interpretation of the strings - it just passes them to the native APIs

I copied that string from a working C/C++ PDH example. To me it seems Tx.Windows does a lot more than is actually necessary and that's where that is coming from.
