性能计数器按进程 ID 而不是名称？

发布于 2025-01-02 15:04:42 字数 570 浏览 0 评论 0原文

我正在跟踪同一应用程序的多个实例，并且需要获取两个进程的内存和 CPU 使用情况。但是，我似乎无法找出使用性能计数器并知道哪个结果适用于哪个进程的方法。我已经看到我可以将 #1 等附加到名称末尾以获得每个结果，但这并不能告诉我哪个进程适用于哪个进程。

如何确定 ProcessId 或将进程 ID 传递给计数器以获取每个同名进程的结果？

PerformanceCounterCPU.CategoryName = "Process";
PerformanceCounterCPU.CounterName = "% Processor Time";
PerformanceCounterCPU.InstanceName = proc.ProcessHandle.ProcessName;

PerformanceCounterMemory.CategoryName = "Process";
PerformanceCounterMemory.CounterName = "Working Set - Private";
PerformanceCounterMemory.InstanceName = proc.ProcessHandle.ProcessName;

I am tracking multiple instances of the same application and need to get the memory and cpu use of both processes. However, I cant seem to figure out a way to use the performance counter and know which result is for which process. I have seen that I can append #1 and such to the end of the name to get results for each, but that doesn't tell me which one is for which process.

How can I determine the ProcessId or pass the process ID to the counter to get the result per each process with same name?

PerformanceCounterCPU.CategoryName = "Process";
PerformanceCounterCPU.CounterName = "% Processor Time";
PerformanceCounterCPU.InstanceName = proc.ProcessHandle.ProcessName;

PerformanceCounterMemory.CategoryName = "Process";
PerformanceCounterMemory.CounterName = "Working Set - Private";
PerformanceCounterMemory.InstanceName = proc.ProcessHandle.ProcessName;

相关问题的此答案可能有效：

private static string GetProcessInstanceName(int pid)
{
  PerformanceCounterCategory cat = new PerformanceCounterCategory("Process");

  string[] instances = cat.GetInstanceNames();
  foreach (string instance in instances)
  {

     using (PerformanceCounter cnt = new PerformanceCounter("Process",  
          "ID Process", instance, true))
     {
        int val = (int) cnt.RawValue;
        if (val == pid)
        {
           return instance;
        }
     }
  }
  throw new Exception("Could not find performance counter " + 
      "instance name for current process. This is truly strange ...");
}

This answer to a related question might work:

private static string GetProcessInstanceName(int pid)
{
  PerformanceCounterCategory cat = new PerformanceCounterCategory("Process");

  string[] instances = cat.GetInstanceNames();
  foreach (string instance in instances)
  {

     using (PerformanceCounter cnt = new PerformanceCounter("Process",  
          "ID Process", instance, true))
     {
        int val = (int) cnt.RawValue;
        if (val == pid)
        {
           return instance;
        }
     }
  }
  throw new Exception("Could not find performance counter " + 
      "instance name for current process. This is truly strange ...");
}
