lpExitTime [out] A pointer to a FILETIME structure that receives the exit time of the process. Maybe because I ran it as admin? I save this value and the next time I check it (every 1.5 seconds - the refresh rate), I decrease it from the last value giving me the raw output of Go to top Permalink | Advertise | Privacy | Terms of Use | Mobile Web02 | 2.8.170106.1 | Last Updated 30 Jan 2006 Article Copyright 2005 by Gil.SchmidtEverything else Copyright ©

string CpuUsage; Thread.Sleep(RefreshInterval); while (KeepCalculation) { NewRawUsageValue = GetCurrentUsageValue(); CpuUsage = ((int)((NewRawUsageValue - OldRawUsageValue) / RefreshInterval)).ToString() + "%"; Thread.Sleep(RefreshInterval); OldRawUsageValue = NewRawUsageValue; } } The API approach After I was left Performance counter is too bloated functionality for this purpose. –xylosper Apr 7 '15 at 13:16 You've probably already seen this, but here's something on how CPU usage is calculated Share a link to this question via email, Google+, Twitter, or Facebook. For me it now returned a value for every process (but the System Idle process).

More info here. Maybe because I ran it as admin? The solution I created a PerformanceCounter for the CPU idle process and got its usage %, then I used Process.GetProcesses() to get a Process[] array.

windows cpu-usage share|improve this question asked Apr 7 '15 at 12:51 xylosper 458514 Why not use process performance counters? –Richard Apr 7 '15 at 12:56 @Richard All quark says: May 11, 2012 at 07:32 In the following code: TotalTime:=int64(mKernelTime.dwLowDateTime or (mKernelTime.dwHighDateTime shr 32)); ‘shr' should be ‘shl' ? Over time, they should average out to the same, though. But mostly THANKS again for the code!

Surprisingly, I found many C++ articles on this and even some old VB code. C# Get Cpu Usage Of Process The correct conversion is (((UInt64)f.dwHighDateTime) << 32) | (UInt32)f.dwLowDateTime. We are not locking anywhere to Exit out of the lock are we? The critical section run count enables the code to be called in a multi-threaded environment without problems.

I will explain in this article the most efficient way I could find to calculate it for both processes and threads. my review here Code: int iFunGetTime( FILETIME ftTime ) { SYSTEMTIME stTime; int iTime; FileTimeToSystemTime( &ftTime, &stTime ); iTime = stTime.wSecond * 1000; iTime += stTime.wMilliseconds; return iTime; } int iFunGetCpuProcUsage( HANDLE hHandle ) Getprocesstimes Example If you have any feedback, please tell us.

The other methods are to help in the calculations.

March 27, 2010 at 12:33 pm I would disagree to sentence "Kernel, User, and Idle sum to total time, which is approximately wall-time." Idle time returned from GetSystemTimes is most probably Queryprocesscycletime Notice any improvements to be made?

I migrated the code by following ejor's article Get CPU Usage with GetSystemTimes. Return value If the function succeeds, the return value is nonzero. I will have a look later.

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. You will need to translate into C++, if that is the language you are working in. P.C. The class stores the time values for a single process, which it needs in order to calculate cpu usage.

Should we kill the features that users are not using frequently, to improve performance? The sample driver program now demos using multiple threads using the CpuUsage class to show thread safety. I would like to know if anyone has any suggestions regarding my code. Before getting to the equation and code, let’s discuss the different types of time available.
