XE Profiler looks promising and can be really a great feature. We can use it with no issues on any version of SQL Server which supports extended events – not only with newest SQL Server 2017. I tested it with SQL Server 2014 and it was working well. Currently, lack of configuration of new templates, and logic based on hard-coded names is the biggest concern and discomfort for the user. However Microsoft didn’t officially release yet this version of SQL Server Management Studio, so it’s hard to say what will be the final feature functionality.
I’m hoping that when the final version appears, it will be good enough to get people finally to kick the Profiler habit.
