As you have mentioned that your code is working for single process or program ,
please let me know what i need to add to the exiting code.
please!!
i want a code that takes a program name as argument and gives it cpu utilization as output.

thank u.

Idle time returned from GetSystemTimes is most probably a part of the Kernel time.

GetProcessTimes returns Kernel time without any Idle time periods because they belong to a different process.

So, the calculation takes the Idle time into account but I would say, it is correct.

For GetSystemTimes(), I think your only solution is to use the officially-unsupported function NtQuerySystemInformation (http://msdn.microsoft.com/en-us/library/ms724509(VS.85).aspx, look for SYSTEM_PROCESSOR_PERFORMANCE_INFORMATION). I would put usage of this inside some #ifdef so it’s only used in Windows 2000/XP, because this method could change or be removed in future versions of Windows.

I wanted to use your program for my project, but the code uses GetSystemTimes() and GetTickCounts() which don’t seem to be supported by XP/2000. Is there a quick fix for that?

Thanks ,
Remy

p/s: Nice to meet you.

I would not expect it to match task manager exactly–they are measuring the program at different times, so there will be a little difference. Over time, they should average out to the same, though.

static void Main(string[] args)
{
Console.WriteLine(“Input:”);
string processName = Console.ReadLine();
usage.setProcessName(processName);

ThreadPool.QueueUserWorkItem(EatItThreadProc);
ThreadPool.QueueUserWorkItem(EatItThreadProc);

ThreadPool.QueueUserWorkItem(WatchItThreadProc);
ThreadPool.QueueUserWorkItem(WatchItThreadProc);

while (true)
{
Thread.Sleep(1000);
}
}

Can you explain for me?

Moreoverer, I try to compare your program and Task manager of Window, they have a little difference. So, your program ran exactly?

Thanks for your reply!

Thanks,

Any idea how to make this just one exe program so that I can copy the exe file to any machine and run the program?
I havent been able to get past the objects problem, but I modified my program to accept command line arguments, so I’ll just put this into a batch file and run it.

Any ideas?

that approach doesnt work…
usage[i] will never be initialized to any value. Trying to work on this further

Regards, Deekshit I can get it to work if I create the CpuUsage objects in this way:

Assuming I want to monitor 2 processes

CpuUsage usage1 = new CpuUsage();
CpuUsage usage2 = new CpuUsage();

and then I can run usage1.getUsage(procName[i]);
and usage2.getUsage(procName[i+1]);

and this approach works, but is not dynamic at all..any tips on how I can get around this problem?

Is this what you are referring to Ben? I seem to be a bit lost here. Can you please help Ben?
