Pro SQL Server 2012 Extended Events gives you the edge in diagnosing and troubleshooting performance and other problems by providing visibility into the database engine and what it is doing, and where processing and elapsed time is being consumed. Support for extended events came in SQL Server 2008 Release 2, and is enhanced in SQL Server 2012. It is safe to say that the extended events framework is now possibly the single most important diagnostic tool that a database administrator can wield.

You can also spot blocking activity, such as might occur when another session access the same data in a conflicting manner.
