Need Help in extended events SQL Server
This isn't answering your question, but please be careful with extended events.  This one has no filters on it at all, so it's collecting a lot of data.  If this is run on a small test box then you won't know and won't care.  If you ran this on a highly transactional production system then there's a good chance your users would be able to tell you that something bad is happening.

If you want to know more about extended events read Jonathan Kehayias's work.

If you have a PluralSight subscription he and his coworker Erin Stellato have some great videos teaching you a lot more on this subject.
