vaishali July 8, 2010 at 2:20 am Deekshit, As you have mentioned that your code is working for single process or program , please let me know what i need to cpuCounter = new PerformanceCounter(); cpuCounter.CategoryName = "Processor"; cpuCounter.CounterName = "% Processor Time"; cpuCounter.InstanceName = "_Total"; Then to get the CPU usage in % just call cpuCounter.NextValue() Source:http://zamov.online.fr/EXHTML/CSharp/CSharp_927308.html share|improve this answer answered So, your program ran exactly?

For the process-specific memory information, you ahve to look at /proc/self/status, which looks like this: Name: whatever State: S (sleeping) Tgid: 19340 Pid: 19340 PPid: 19115 TracerPid: 0 Uid: 0 0 So the total is actually the current swap total. So 15 milliseconds in your program is a 1% of CPU usage. Probably personal preference but the code seemed more readable for me that way.

Another approach is to access the appropriate performance counter using PDH.

So, the difference between these values obtained during an interval will yield you total CPU usage for that interval. Here are some of the things I found. C# Get Cpu Usage Of Process

However, we still need the Win32 API call for getting the total system times (GetSystemTimes). The memory stats are for the actual memory. This function gets us four parameters CreationTime, ExitTime, KernelTime and UserTime. click site I also start two threads to access the usage object and poll the CPU usage in order to demonstrate the thread safety of the object. 1: // CpuUsageCpp.cpp : Defines the

To get the process time you will need to call GetProcessTimes(), which returns the creation, exit, kernel, and user time given the process handle.
