Report Generator timing info in VS 'Report a problem' #68401

Open chsienki opened 1 year ago

chsienki commented 1 year ago

The generator driver has the ability to capture information about generator timing via an ETW event source called Microsoft-CodeAnalysis-General

When using the 'Report a problem' tool inside Visual Studio, certain ETW providers are turned on and captured in the trace. We should add Microsoft-CodeAnalysis-General to these providers so that the timing information is captured and allows us to quickly see if a misbehaving generator is causing any slowness.

Note: there is already a roslyn ETW provider included in the traces RoslynEventSource but we can't use it in this case as it's declared in the workspaces layer rather than the compiler layer.

This hasn't yet closed on the VS side, so leaving it here for tracking until it does. (see https://devdiv.visualstudio.com/DevDiv/_git/Setup-Engine/pullrequest/485095)
