Advanced Viewing of Target Data from Extended Events in SQL Server
When your event session is currently active, you might want to watch the event data in real time, as it is received by the target.
Management > Extended Events > Sessions > [your-session] > Watch Live Data.
The query_post_execution_showplan extended event enables you to see the actual query plan in the SQL Server Management Studio (SSMS) UI. When the Details pane is visible, you can see a graph of the query plan on the Query Plan tab. By hovering over a node on the query plan, you cansee a list of property names and their values for the node.
