选择PerformanceCounterType

Question

这是个问题.我正在开发一个名为CreateCounters的方法,它将为应用程序创建性能计数器.该方法包括以下代码.

void CreateCounters()
{
     if(!PerformanceCounterCategory.Exists("Contoso"))
     {
         var counters = new CounterCreateationDataCollection();
         var ccdCounter1 = new CounterCreationData
         {
             CounterName = "Counter1";
             CounterType = PerformanceCounterType.SampleFraction;
         };
         counters.Add(ccdCounter1);
         var ccdCounter2 = new CounterCreationData
         {
             CounterName = "Counter2";
             // need insert PerformanceCounterType
         };
         counters.Add(ccdCounter2);
         PerformanceCounterCategory.Create("Contoso","Help dtring",
         PerformanceCounterCategoryType.MultiInstance, counters);
    }
}

我需要确保Counter1可用于Windows性能监视器(PerfMon).你应该插入哪个代码段？

有四种选择.

A. CounterType = PerformanccCounterType.RawBase
B. CounterType = PerformanceCounterType.AverageBase
C. CounterType = PerformanceCounterType.SampleBase
D. CounterType = PerformanceCounterType.CounterMultiBase

我不知道是哪一个,为什么？

Answer 1

看到这个:

https://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountertype%28v=vs.110%29.aspx

那里有一个表显示PerformanceCounterType.SampleFraction需要一个PerformanceCounterType.SampleBase类型的denomonator

(和RawFraction需要RawBase等)
