创建PerfMon计数器以记录每次调用的平均值（C＃）

如何使用PerfMon计数器记录C＃中方法的平均执行时间？

到目前为止，我只找到了增加或减少PerfMon计数器的示例代码。

Answer 1

这是我曾经写过的一些示例代码。

首先，您需要指定并安装有问题的性能计数器。 您可以使用安装程序执行此操作：

public class CreditPerformanceMonitorInstaller : Installer { private PerformanceCounterInstaller counterInstaller_; public CreditPerformanceMonitorInstaller() { this.counterInstaller_ = new PerformanceCounterInstaller(); this.counterInstaller_.CategoryName = CreditPerformanceCounter.CategoryName; this.counterInstaller_.CategoryType = PerformanceCounterCategoryType.SingleInstance; CounterCreationData transferAverageData = new CounterCreationData(); transferAverageData.CounterName = CreditPerformanceCounter.AverageTransferTimeCounterName; transferAverageData.CounterHelp = "Reports the average execution time of transfer operations"; transferAverageData.CounterType = PerformanceCounterType.AverageTimer32; this.counterInstaller_.Counters.Add(transferAverageData); CounterCreationData transferAverageBaseData = new CounterCreationData(); transferAverageBaseData.CounterName = CreditPerformanceCounter.AverageTransferTimeBaseCounterName; transferAverageBaseData.CounterHelp = "Base for average transfer time counter"; transferAverageBaseData.CounterType = PerformanceCounterType.AverageBase; this.counterInstaller_.Counters.Add(transferAverageBaseData); this.Installers.Add(this.counterInstaller_); } public Installer PerformanceCounterInstaller { get { return this.counterInstaller_; } } } 

要写入性能计数器，您可以这样做：

 public void RecordTransfer(long elapsedTicks) { using (PerformanceCounter averageTransferTimeCounter = new PerformanceCounter(), averageTransferTimeBaseCounter = new PerformanceCounter()) { averageTransferTimeCounter.CategoryName = CreditPerformanceCounter.CategoryName; averageTransferTimeCounter.CounterName = CreditPerformanceCounter.AverageTransferTimeCounterName; averageTransferTimeCounter.ReadOnly = false; averageTransferTimeBaseCounter.CategoryName = CreditPerformanceCounter.CategoryName; averageTransferTimeBaseCounter.CounterName = CreditPerformanceCounter.AverageTransferTimeBaseCounterName; averageTransferTimeBaseCounter.ReadOnly = false; averageTransferTimeCounter.IncrementBy(elapsedTicks); averageTransferTimeBaseCounter.Increment(); } } 

Answer 2

看一下不同的PerformanceCounterTypes 。 计算平均时间或计数有几种类型。 您还会找到一些例子。

希望这可以帮助。
