Event Tracing for Windows (ETW) is an efficient kernel-level tracing facility that enables profiler log kernel or application-defined events. The data that is collected from the event provider can be viewed only by using the /Summary:ETW option of the VSPerfReport command-line tool. You can use this report to determine where performance issues occur in the application.
To enable event trace providers
In Performance Explorer, right-click the performance session, and then click Properties.
In the Property Pages, click the Windows Events properties.
In the Select event trace provider to collect data from list, select the event providers that you want to use to profile your application.
