ETW, .NET 4.5 - how to write to the event log?

.net-4.5 event-log etw

I am trying to wrap my head around ETW and how to integrate t into a high Performance application.

We all know the old dreaded EventLog with it's non structured (and thus not so optimal) API.

Now there is a new and fancy API for high performance tracing - ETW, and it got a new API on the .NET side in 4.5 in the form of the EventSource class that you can easily subclass (so no more manifest writing).

THis leaves me with a number of questions, trying to get this working.

  • What is the current proposed best (as per documentation, Guidelines) way to work with ETW and get Events from there into the EventLog? I have an application here that must write (Performance) Events and would love to use ETW; but the Events shall appear in a (custom) Event log.
  • Is there a complete example for this? I can find some, but they all date to the .NET 4.0 time and start with the manifest.

What did I try? I got an EventSource working, but simply have failed to get the proper documentation on how to get the rest working Downstream from there.

In August 2013, Microsoft.Diagnostics.Tracing.EventSource 1.0.4 beta released on NuGet. The three big wins are channel support, static (installed) manifest support (the two things required to get into the Event Viewer) and .NET 4.0 support.

According to the blog post announcing RTM, Microsoft.Diagnostics.Tracing.EventSource "enables fast app tracing to the Windows Event Log, including in production".
