Many of its features such as windows and icons would later become commonplace in GUIs.
It is extensible, which means that you can add your own information that is relevant to your code. This blog is about doing 3. You can also watch the video of me going through the steps below. This discouraged most users from ever building their own ETW providers, which is a shame because it is a powerful feature of ETW.
NET Runtime Now available for download, as a release candidate. It will officially ship later in It makes writing ETW provider as simple as writing just a few lines of code. The first step in logging ETW events is to decide what we need to log.
We need to decide on a name for the provider, as well as the events and all their payloads. You can do this with just a few lines of code using EventSource.
For example the code sealed class MinimalEventSource: So for the text in bluewe are just specifing what we want what the 'shape' of the event is. Ideally this is all that we would specify, however to 'hook it up' we need to write a SMALL amount of 'boiler plate' code.
EventSource does the rest. That is not so bad! The code in green simply creates a global variable called 'Log' which holds our EventSource typically you only make one for the whole app. So, how do you turn it on.
If you are not familiar with PerfView check out the Tutorial Videos. Perfview has some special support for EventSources that make it particularly easy to use. Lets assume we compiled the code above into an application called 'EventSourceDemo. The 'run' command then specifies that the rest of the command line should be executed as a command while those providers are active.
The result is a file because we did not specify it is called 'PerfViewData.
After creating that file PerfView immediately opens it. The result is probably a display that looks like this On the left, you wee the PerfViewData. If you open it you see various 'Views' of the data in that file. The one we care about right now is is the 'Events' view.
Double clicking on that brings up the Event Viewer. On the left you see all the events from all the ETW event providers that were captured in the file.
You can see in the above case the event that we logged in our sample code. Just what you might expect. OK Now your turn. At the end of the article is a ZIP archive of all the source code for EventSoruceDemo it is actually significantly more complex that what I have shown above there is a lot that I have not told you yet.
Thus you can try this out by doing Extract the files in the ZIP file below. Open a command window in the PerfViewDemoV3. Since you have the complete source, you can recompile it using Visual Studio Free version here to see how changing the code changes the events being logged.
You can also use the EventSource.Computer programming is designing and writing software, or programs, for the computer to load and execute.
