使用PerformanceCounter跟踪每个进程的内存和CPU使用情况？

Question

如何使用System.Diagnostics.PerformanceCounter跟踪进程的内存和CPU使用情况？

Answer 1

对于每个流程数据：

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)+" %");
}

性能计数器还有其他计数器，而不是工作集和处理器时间。

Answer 2

我想你想要Windows Management Instrumentation.

Answer 3

如果您使用的是.NET Core，则System.Diagnostics.PerformanceCounter不是一个选择。尝试以下方法：

System.Diagnostics.Process p = System.Diagnostics.Process.GetCurrentProcess();
long ram = p.WorkingSet64;
Console.WriteLine($"RAM: {ram/1024/1024} MB");
