App-V debug logs in event viewer

Question
-
While I understand how to enable the debug logs in event viewer for the App-V client and that they have been consolidated, what I need to know is which one needs to be enabled for catching VFS issues?

if this is appv 5.1, the service log in event viewer is as below:
if it is windows 10 AppV, the most service log has been redirected to telemetory channel, but can be captured by the following ETW GUID

using Microsoft Message Analyzer can help on the capturing:

The App-V debug event logs are not likely to help diagnose a VFS issue. Procmon is likely to be a better choice.

Hi Tim,
Unfortunately, I am not any good with procmon.

Yes, this is the new change in windows 10 since 1709 if my memory serves me correctly. A lot of verbose debugging logs has been moved to telemetry channel - 271aebf7-e83b-580f-7525-5e9563fe161a and no show from regular event viewer logs. You can use the following command to get all the logs in win10:
logman /create Trace AppV -p {9CC69D1C-7917-4ACD-8066-6BF8B63E551B} -o c:\Temp\AppVAll.etl logman /update Trace AppV -p {E4F68870-5AE8-4E5B-9CE7-CA9ED75B0245} logman /update Trace AppV -p {271aebf7-e83b-580f-7525-5e9563fe161a}

These are not pre-created but left disabled? Very odd.
