Creating a PerfMon counter to record an average per call (C#)

Question

How can I use PerfMon counters to record the average execution time of a method in C#?

So far I've only found sample code to incrememnt or decrement a PerfMon counter.

Here's some sample code I once wrote to do exactly that.

First, you need to specify and install the performance counters in question. You can do this by using an Installer:

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_; }     } } 

To write to the performance counter, you can do it like this:

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();     } }
