PostSharp.Samples / PostSharp.Samples.Logging.Etw
Project Description

This example demonstrates how to configure the PostSharp Logging aspect so that it prints its output to ETW.

Program.cs is the only interesting one file. The other classes are members of the PostSharp.Samples.Logging.BusinessLogic namespace and only simulate some business logic.

The [assembly: Log] custom attribute in Program.cs adds logging to the whole project. However, the [Log(AttributeExclude = true)] attribute on the Program class prevents the Program class itself from being logged. This is required because no logged code is allowed before the logging service is initialized.

The first line of the Program.Main method initializes PostSharp Logging. The method then executes the business code to produce some output in the log.

Viewing the log

To view the log produced by this example, you need to attach a log collector:

  1. Download PerfView from https://www.microsoft.com/en-us/download/details.aspx?id=28567.

  2. Execute: perfview.exe collect -OnlyProviders *PostSharp-Patterns-Diagnostics

  3. Execute this program.

  4. In PerfView, click 'Stop collecting', then in the PerfView tree view click 'PerfViewData.etl.zip' and finally 'Events'.
