Warning in advance: I'm so sorry for all the comments in the code :x Also, if you copy this code and run it, it's going to generate a .CSV file called Regards, Deekshit Ben Post authorMarch 6, 2009 at 12:15 pm I think you have the right idea with the array.

That should lead you to advice about which headers and libs are necessary. just call GetCPULoad() at regular intervals (e.g. Sign in using Search within: Articles Quick Answers Messages home articles Chapters and Sections> Search Latest Articles Latest Tips/Tricks Top Articles Beginner Articles Technical Blogs Posting/Update Guidelines Article Help Forum Article

I seem to have the memory and logging part taken care of, but figuring out the CPU percentage has been very tough :( I've found a lot info on methods to So, the calculation takes the Idle time into account but I would say, it is correct.

What I guess I'm saying here is, just because you see something in an Import table doesn't really mean you've figured out how a program works. Get Cpu Usage C++ For example, when you look up PdhEnumObjectItems() in MSDN, it shows which headers and libs you need to use. Add the two together, and you have its total CPU utilization. Check This Out And some people on the forums have written scripts.

float GetCPULoad() { FILETIME idleTime, kernelTime, userTime; return GetSystemTimes(&idleTime, &kernelTime, &userTime) ? Pdhopenquery I will tell you however that NtQuerySystemInformation has many other functions that Task Manager can make use of for getting information on the System Cache, page file, handles, and many other More info here. cpu load = int( (SystemTime - IdleTime) *100 / Systemtime ); I am a little confused by the DLLCall itself though.

Actually your code is still better than what I could produce even if I had an extended project timeline. http://patuxentpc.com/calculate-cpu-usage-in-cc/ 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 C++ Get Cpu Usage Linux So in order to calculate a meaningful load percentage, you have to examine what percentage of time the CPU was idle during a particular interval of time.

Total Virtual Memory This one is tricky on Mac OS X because it doesn't use a preset swap partition or file like Linux. Messages: 41,753 Joined: Nov 5, 2005 Don't know if this needs to be a Win32 app or not, but the .NET managed framework has a lot of this stuff encapsulated and Ascend4nt has an excellent script. this content I am not really good at C#, just a beginner..so could you help me out with this one please? -Deekshit Deekshit February 5, 2009 at 7:51 am Hi, I found the

Someone should probably tell Microsoft then: http://msdn.microsoft.com/en-us/library/windows/desktop/ms724509(v=vs.85).aspx Feb 28, 2014 at 5:13pm UTC kbw (8006) Yes, it's "undocumented", despite a page being available for it. Getprocesstimes WTM doesn't have any obvious Imports for calculating Process % CPU usage, so who knows, it may use Performance data queries for that. mikeblas, Feb 3, 2009 mikeblas, Feb 3, 2009 #11 (You must log in or sign up to reply here.)

What does this bus signal representation mean Politely asking for more work as an intern Why is my scene rendered repeatedly when I press F12? Also, you should check out the updated code samples-they use interlocked operations instead of locking, so they are much more efficient and performant now.

I've probably spend more time thinking about this than I had originally planned...

DLL Requires Kernel32.dll. It is still possible for cached pages to be reactivated Free pages that are completely free and ready to be used. The other is it will return the cpu usage (processor usage) based on ALL of the systems processors. Maybe I'm missing the point, but it seems like a popular way to figure this out is by querying the CPU two times with at least 200ms between each check to

In the sample you can find the use of GetSystemTimes and GetProcessTimes and a little class to do everything.class CPU { public: CPU( void ); ~CPU( void ); // return : I'm going to add some unit tests and finished code, unless someone else wants to use this as a tool. –kayleeFrye_onDeck Apr 18 '14 at 17:41 @jeremy is there
