Using PerformanceCounter to track memory and CPU usage per process?


How can I use System.Diagnostics.PerformanceCounter to track the memory and CPU usage for a process?


Solution

  • For per process data:

    Process p = /*get the desired process here*/;
    PerformanceCounter ramCounter = new PerformanceCounter("Process", "Working Set", p.ProcessName);
    PerformanceCounter cpuCounter = new PerformanceCounter("Process", "% Processor Time", p.ProcessName);
    while (true)
    {
        Thread.Sleep(500);
        double ram = ramCounter.NextValue();
        double cpu = cpuCounter.NextValue();
        Console.WriteLine("RAM: "+(ram/1024/1024)+" MB; CPU: "+(cpu)+" %");
    }
    

    Performance counter also has other counters than Working set and Processor time.
