Getting Processor Usage from LabVIEW

[Chris Davis]

I was contemplating adding a processor usage display to one of my CPU hungry programs. At NI week 2007, one of the demo's, specifically one on Tuesday demonstrating the new multi-core parts of the timed loop had such a display. Does anyone know how they did it, or how I might add such a display to my program?

Thanks

My best bet is .Net although I think the WinAPI will also give you this information on a somewhat lower level and probably not exactly trivial to access. Possibly LabVIEW has some private hooks itself. Would make sense to have this info in LabVIEW somehow to make it platform independant.

There is a LabVIEW example "SimpleTaskMonitor" that uses the .NET interface to get information from the performance counters in the system assembly.

Download the demo code from the NI-WEEK Whats new in LV RT presentation. That should have the properties or whatever that exposes processor usage.

Unfortunately, I have not yet upgraded to 8.5 (waiting for my LV-RT 8.5 disk on SSP) so I can't open it and give you a screen shot.
