【问题描述】：

如何在一个应用程序 (.exe) 中定义和使用两个 AverageTimer32 性能计数器？

附加说明： 我正在尝试衡量在操作的不同部分花费的时间。

我有一个 AverageTimer32 性能计数器和一个 AverageBase。它有效。

现在我想添加第二个 AverageTimer32 性能计数器。即使我添加另一个 AverageBase 计数器，它也不起作用。我想我错了。代码示例非常感谢。

这是代码的不同部分：

_AverageDuration = new PerformanceCounter();
_AverageDuration.CategoryName = CategoryName;
_AverageDuration.CounterName = "average time per operation";
_AverageDuration.MachineName = ".";
_AverageDuration.ReadOnly = false;

_AverageDurationBase = new PerformanceCounter();
_AverageDurationBase.CategoryName = CategoryName;
_AverageDurationBase.CounterName = "average time per operation base";
_AverageDurationBase.MachineName = ".";
_AverageDurationBase.ReadOnly = false;
...
CounterCreationDataCollection counters = new CounterCreationDataCollection();
...
CounterCreationData avgDuration = new CounterCreationData();
avgDuration.CounterName = "average time per operation";
avgDuration.CounterHelp = "Average duration per operation execution";
avgDuration.CounterType = PerformanceCounterType.AverageTimer32;
counters.Add(avgDuration);

CounterCreationData avgDurationBase = new CounterCreationData();
avgDurationBase.CounterName = "average time per operation base";
avgDurationBase.CounterHelp = "Average duration per operation execution base";
avgDurationBase.CounterType = PerformanceCounterType.AverageBase;
counters.Add(avgDurationBase);
...
PerformanceCounterCategory.Create(CategoryName, "Category for Receiver", PerformanceCounterCategoryType.Unknown, counters);
...
AverageDuration.IncrementBy(performanceCounterwatch.ElapsedTicks);
AverageDurationBase.Increment();

【问题讨论】：

顺便说一句，您可以考虑使用Using XSLT to Generate Performance Counters Code 之类的东西以避免重复所有代码

【参考方案1】：

添加它们的顺序很关键。您必须添加平均值，然后是其对应的基数，然后是第二个平均值，然后是第二个对应的基数。

我（认为）还必须删除该类别并使用新的性能计数器再次添加它。
