Performance counters

[Sparkette]

Is there any way to read data from Windows NT performance counters into LabVIEW? Yes, I know it's a short post.

Check out the API from MSDN -- it looks like there's a registry-based query method but you might end up having to use DLL calls.

If memory serves, the DLL calls (at least the basic one) is fairly simple and there should already be example VIs available. Try searching for "QPC" or "QueryPerformanceCounter".

I'm not sure what those are, but if you want to monitor performance parameters like Processor usage etc. there are already VI's on NI's website that use .NET calls to achieve this.
