性能計數器類別名稱？ （C＃）

Question

我試圖在性能計數器到我的C＃應用​​程序，啓動另一個進程，並檢查啓動過程的處理器使用編程。據我瞭解，性能計數器類要求我分配一個類別名稱，一個計數器名稱和一個進程名稱。我可以很容易地得到進程名稱，但是在互聯網上是否有一個列表有我可以分配的所有可能的類別和計數器名稱？我試圖爲MSDN搜索這樣的東西，但我沒有找到任何東西。

感謝您的幫助！

Answer 1

我想你想知道你可以監視的過程的哪些方面。過程性能計數器列表可用here 儘管如此，您仍然可以使用靜態方法列出機器中的所有類別，或者您可以更具體地爲「過程」類別創建PerformanceCategory，並使用GetCounters來獲取列表的所有可用計數器。 希望這有助於。

Answer 2

您可以將它們分配任何你想要的。性能監視器將簡單地顯示您選擇的任何類別以及您爲特定需求選擇的任何計數器名稱。

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

我已經創建了顯示什麼CriGoT在上面創作的，一個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(); 
} 

希望得到這個幫助。

對於那些誰想要快速瀏覽和查找所需的反這裏有一個快速表單顯示三個列表框與|Categories|Instances|Counters|和被一個計時器更新計數器值。帶過濾器。
