Is there a way to monitor CPU usage during the execution of a vi?

[PA_UW]

I am wondering if there is a way, using LabView, to monitor the CPU usage during the execution of a vi. I want to be able to programmatically adjust the program controls based on the CPU usage. This program is designed to run all day in the background.

Thanks!

LabVIEW 7 offers a very elegant way to do this using .NET technology.

There are at least two Windows tools you can use to see CPU usage
(depending on what version of Windows you have). The Task Manager
(ctrl-alt-del) has a panel that shows CPU usage. There is another
program that has more options as to what to watch. Under W2K, it is in
the Administrative Tools in the Control Panel and is called Performance.
Play around with adding various new "Counters".
Another option is to measure CPU usage programmatically. George Zou

has a tool that makes the appropriate dll call. Check out

Thanks.

I also found the other post on here about the NI Example SimpleTaskMonitor.vi.  I had to search for .NET in keywords or CPU Usage in description to find it.
