EventWriteTransfer method appearing under Hotspots in Timeline Viewer

I'm using the Timeline Viewer to examine a snapshot.

When I check the Awaits box in the Call Tree tab for some of my methods, the top method in the Hotspots tab is a method named Interop+Advapi32.EventWriteTransfer. I'm not calling this explicitly anywhere. It appears to part of the ETW system.

Is this something that dotTrace is calling during profiling? How should I interpret the time spent in this method?

Thank you for contacting us.

This method time is really overhead from ETW. You should ignore this time by performing “Exclude Method” in the context menu on selected method. We’ve create the corresponding issue: https://youtrack.jetbrains.com/issue/DTRC-28611/Eclude-ETW-methods-from-the-snapshot. You are welcome to follow and vote for it.
