性能計數器集合

Question

有什麼辦法可以獲得性能計數器的集合嗎？

我的意思是，而不是創建幾個性能計數器，如

PerformanceCounter actions = new PerformanceCounter("CategoryName", "CounterName1","instance"); 
PerformanceCounter tests = new PerformanceCounter("CategoryName", "CounterName2", "instance"); 

我想獲得一個集合（類別名稱），其中每個項目將是一個CounterName項目。

所以沒有必要在單獨的櫃檯創作。

按照你的描述我相信你想創建自定義計數器。您可以一次創建計數器，但您必須逐個創建實例。使用CounterCreationDataCollection和CounterCreationData類。首先，創建計數器數據，將它們添加到新的計數器類別，然後創建自己的實例：

//Create the counters data. You could also use a loop here if your counters will have exactly these names. 
CounterCreationDataCollection counters = new CounterCreationDataCollection(); 
counters.Add(new CounterCreationData("CounterName1", "Description of Counter1", PerformanceCounterType.AverageCount64)); 
counters.Add(new CounterCreationData("CounterName2", "Description of Counter2", PerformanceCounterType.AverageCount64)); 

//Create the category with the prwviously defined counters. 
PerformanceCounterCategory.Create("CategoryName", "CategoryDescription", PerformanceCounterCategoryType.MultiInstance, counters); 

//Create the Instances 
CategoryName actions = new PerformanceCounter("CategoryName", "CounterName1", "Instance1", false)); 
CategoryName tests = new PerformanceCounter("CategoryName", "CounterName2", "Instance1", false)); 

我的建議是不要使用通用名稱作爲計數器名稱。創建計數器之後，您可能想要收集其數據（可能是通過性能監視器），因此而不是使用CounteName1作爲計數器表示的名稱（例如，動作，測試...）。

爲了得到一個特定類別的所有計數器一次創建計數器類的一個實例，並使用GetCounters方法：

PerformanceCounterCategory category = new PerformanceCounterCategory("CategoryName"); 
PerformanceCounter[] counters = category.GetCounters("instance"); 

foreach (PerformanceCounter counter in counters) 
{ 
    //do something with the counter 
}
