How Do I Get The CPU Useage Of A Program?

4 posts in this topic

Iv Seen The '_ProcessListProperties' But I Can't Seem To Get It To Work Could Someone Maybe Post A Little Function To Get The CPU Usage On 1 Process? Thanks :3

What happened when you tried _ProcessListProperties()?

You could extract from that function just the part that gets the CPU usage, but the time-based properties require the SwbemRefresher part so that will not save you much using WMI.

Using the DLLs directly for this is over my head, but maybe others know how to get it that way.

It is a CMD tool. So start it in CMD but before you do it start Calc.exe.

(don't forget to increase Screen Buffer Size in CMD to a higher value than 80. E.g. 160, otherwise output will be printed always to next line)

Afterwards to will see someting like this:

Process Information v0.25 Beta by UEZ

====================================

(Press ESC to exit)

Calc.exe | PID: 4252 | CPU time: 0:00:00.109 (h:m:s.ms) | Mem usage: 5052 MB | CPU usage: 0 %

If you gonna now calculate something then the CPU usage should change, e.g. 123456789! (n!)

Additional remark: my code above can only handle processes from explorer.exe and its subprocesses. :)

To monitor e.g. services code needs to be modified!

Thanks to Paulchen for the hint!
