Bill Anton has a cheat sheet for SSAS performance monitoring extended events:
In this post we ran through the list of Extended Events that you’ll want to collect along with an explanation on the type of performance-related information you can derive from them. Depending on the type of instance you’re monitoring, we’re only really only talking about 5 (multidimensional) or 6 (tabular) events that need to be captured.
If you are in charge of administering Analysis Services cubes, Bill’s series is an excellent way of making sure you’re keeping up on good monitoring practices.
