Get CPU Usage of a process?

[rrand]

Does anyone have any idea how I can get the CPU usage of a process? I want to write a script to alert me if a process starts hogging system resources and then use AutoIt to do something to it to fix it if it's an issue I'm aware of.

I know you can use pstat.exe to find out a lot of information, but I'm not sure how to get % CPU load time like in Windows Task Manager.

Any help would be appreciated! Thanks.

Also there is a program that comes with Windows Resource kits called PMON.exe. It has the CPU load percentage in it for each process, but it runs in DOS in real time. I can't seem to just get a text file snapshot of it or otherwise redirect the output to a file. It runs until you hit Q.
