What I need to be able to detect is when the CPU or CPUs of a system are idle
or no more than 10% busy. Back in my C++ days we used
NtQuerySystemInformation. Is there an easier way built into the .Net
Platform or C#?

I think it in System.Diagnostics.PerformanceCounter. Search for
PerformanceCounter in this group and you should be able to find what
you want.

John,

Thanks for the reply. I found a way to use performance counters but there
seems to be no way to handle multiple CPUs

I don't know what you found out and I don't have multiple CPU machine
to test.

But how about this?
CategoryName = "Process"; // Instead of processor
CounterName = "% Processor Time";
InstanceName = "Idle";
MachineName = "MY-MACHINE";

Thanks John,

Yes, that may work because it is looking at the Idle process itself. I will
have to try it and see what happens.

Please post the result here. I am interested to know also.
