通过进程ID，而不是名称性能计数器？ [英] Performance Counter by Process ID instead of name?

问题描述

我跟踪同一应用程序的多个实例，并需要获得内存和CPU使用两种工艺。不过，我似乎无法找出一种方法使用性能计数器，知道这结果是哪个进程。我已经看到，我可以追加＃1，这样的名称来获得每个结果的结尾，但是这并没有告诉我哪一个是为其过程。

如何确定进程ID或进程ID传递到柜台得到每同名？

$ B每一个过程的结果$ b

  PerformanceCounterCPU.CategoryName =过程; 
 PerformanceCounterCPU.CounterName =％处理器时间; 
 PerformanceCounterCPU.InstanceName = proc.ProcessHandle.ProcessName; 
 
 PerformanceCounterMemory.CategoryName =过程; 
 PerformanceCounterMemory.CounterName =工作集 - 私人; 
 PerformanceCounterMemory.InstanceName = proc.ProcessHandle.ProcessName; 
  

解决方案

的这个答案以一个相关的问题可能的工作：

 私有静态字符串GetProcessInstanceName （INT PID）
 {
 PerformanceCounterCategory猫=新PerformanceCounterCategory（过程）; 
 
的String []实例= cat.GetInstanceNames（）; 
的foreach（以实例的字符串实例）
 {
 $ B $使用B（的PerformanceCounter CNT =新的PerformanceCounter（过程，
标识过程，例如，真）） 
 {
 INT VAL =（INT）cnt.RawValue; 
如果（VAL == PID）
 {
返回实例; 
} 
} 
} 
抛出新的异常（找不到性能计数器+ 
为当前流程实例的名称。这是真正奇怪的...... ）; 
} 
  

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;

解决方案

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 ...");
}
