How to: View ETW Data

After enabling event data, as described in How to: Enable Event Trace Providers, the data can be viewed by using the VSPerfReport command-line tool.


Enabling events data generates additional files that have the .etl extension. This file contains events information and is used by the VSPerfReport to generate .CSV reports.


Command-line tools are located in C:\Program Files\Microsoft Visual Studio 8\Team Tools\Performance Tools> directory.

To view ETW data

  • Open a command line window. At the command prompt, run the following command to start VSPerfReport:

    C:\<path>vsperfreport c:\<path>report_name.vsp /calltrace /output:c:\<path>

    Two reports, report_CallTrace.CSV and report_Header.CSV, are generated. The call trace report contains events information. For information about report columns, see Performance Report Column Definition.
