创建PerfMon计数器以记录每次调用的平均值（C#）

如何使用PerfMon计数器在C#中记录方法的平均执行时间

---

到目前为止，我只找到了递增或递减PerfMon计数器的示例代码。

看看不同的。 计算平均时间或计数有几种类型。你也会发现一些例子

希望这能有所帮助。

以下是我曾经编写的一些示例代码，正是为了做到这一点

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();
    }
}
