Determining service operation duration

  • Article

If analytic tracing is enabled in a Windows Communication Foundation (WCF) application, the duration of execution for a service operation can easily be determined by examining the event log. This topic demonstrates how to determine the amount of time a service operation takes to complete.

Determining service operation execution duration

  1. Open Event Viewer by clicking Start, Run, and entering eventvwr.exe.

  2. If you haven’t enabled analytic tracing, expand Applications and Services Logs, Microsoft, Windows, Application Server-Applications. Select View, Show Analytic and Debug Logs. Right-click Analytic and select Enable Log. Leave Event Viewer open so that traces can be viewed after the service operation is run.

  3. Next, open a WCF application that includes a service project and a client project that interacts with that service. You can create such an application by following the Getting Started Tutorial. If you have the WCF samples installed, you can open the Getting Started Sample, which contains the completed project created in the tutorial.

  4. Execute the server application by pressing F5. Execute the client application by right-clicking on the Client project and selecting Debug, Start New Instance.

  5. In Event Viewer, refresh the Analytic log and sort the events by Event ID. Look for events with Event ID 214 - OperationCompleted. These events will show which operations have completed, and what the duration of the operation was. The following event shows the duration of an Add operation.

    An OperationInvoker completed the call to the 'Add' method.  The method call duration was '3' ms.
