性能计数器类别名称？ （C＃）

Question

我试图在性能计数器到我的C＃应用​​程序，启动另一个进程，并检查启动过程的处理器使用编程。据我了解，性能计数器类要求我分配一个类别名称，一个计数器名称和一个进程名称。我可以很容易地得到进程名称，但是在互联网上是否有一个列表有我可以分配的所有可能的类别和计数器名称？我试图为MSDN搜索这样的东西，但我没有找到任何东西。

感谢您的帮助！

Answer 1

我想你想知道你可以监视的过程的哪些方面。过程性能计数器列表可用here 尽管如此，您仍然可以使用静态方法列出机器中的所有类别，或者您可以更具体地为“过程”类别创建PerformanceCategory，并使用GetCounters来获取列表的所有可用计数器。 希望这有助于。

Answer 2

您可以将它们分配任何你想要的。性能监视器将简单地显示您选择的任何类别以及您为特定需求选择的任何计数器名称。

CounterCreationDataCollection ccdc = new CounterCreationDataCollection(); 
ccdc.Add(new CounterCreationData("Counter Title", "Counter Description", PerformanceCounterType.NumberOfItems32)); 
PerformanceCounterCategory.Create("My Counter Category", "Category Description", PerformanceCounterCategoryType.Unknown, ccdc);

我已经创建了显示什么CriGoT在上面创作的，一个小的快捷方式的方法。

private static void GetAllCounters(string categoryFilter) 
    { 
     var categories = PerformanceCounterCategory.GetCategories(); 
     foreach (var cat in categories) 
     { 
      if (categoryFilter != null && categoryFilter.Length > 0) 
      { 
       if (!cat.CategoryName.Contains(categoryFilter)) continue; 
      } 
      Console.WriteLine("Category {0}", cat.CategoryName); 
      try 
      { 
       var instances = cat.GetInstanceNames(); 
       if (instances != null && instances.Length > 0) 
       { 
        foreach (var instance in instances) 
        { 
         //if (cat.CounterExists(instance)) 
         //{ 
          foreach (var counter in cat.GetCounters(instance)) 
          { 
           Console.WriteLine("\tCounter Name {0} [{1}]", counter.CounterName, instance); 
          } 
         //} 
        } 
       } 
       else 
       { 
        foreach (var counter in cat.GetCounters()) 
        { 
         Console.WriteLine("\tCounter Name {0}", counter.CounterName); 
        } 
       } 
      } 
      catch (Exception) 
      { 
       // NO COUNTERS 
      } 
     } 
     Console.ReadLine(); 
} 

希望得到这个帮助。
