如何使用性能计数器在C＃中监控4个进程具有相同的名称？ [英] How can I use Performance Counters in C# to monitor 4 processes with the same name?

问题描述

我试图创建一个性能计数器，可以监视应用程序的性能时，其中一个是谷歌浏览器。然而，我注意到，演出时间，我得到的铬是不自然低 - 我看任务管理器下实现我的问题，Chrome浏览器在完全相同的名称运行多个进程，但每个进程都有一个不同的工作组大小因此（我会相信）不同的处理器时间。我试着这样做：

I'm trying to create a performance counter that can monitor the performance time of applications, one of which is Google Chrome. However, I notice that the performance time I get for chrome is unnaturally low - I look under the task-manager to realize my problem that chrome has more than one process running under the exact same name, but each process has a different working set size and thus(what I would believe) different processor times. I tried doing this:

// get all processes running under the same name, and make a performance counter
// for each one.
Process[] toImport = Process.GetProcessesByName("chrome");

        instances = new PerformanceCounter[toImport.Length];

        for (int i = 0; i < instances.Length; i++)
        {

           PerformanceCounter toPopulate = new PerformanceCounter
                ("Process", "% Processor Time",
                    toImport[i].ProcessName,
                   true);

            //Console.WriteLine(toImport[i].ProcessName + "#" + i);

            instances[i] = toPopulate;
        }

但是，这似乎并没有在所有的工作 - 我只是监控相同在处理好几倍。谁能告诉我的方式来监测独立进程具有相同的名称？

But that doesn't seem to work at all - I just monitor the same process several times over. Can anyone tell me of a way to monitor separate processes with the same name?

推荐答案

打开性能监视器和外观。您需要使用像铬＃2 或可能的话， chrome_2 。

Open perfmon and look. You need to use names like chrome#2 or, possibly, chrome_2.
