Last night, I received Adam Machanic’s (b | t) newsletter “Announcing sp_whoisactive v11.20: Live Query Plans”.
For those who don’t know about it, sp_WhoIsActive is a stored procedure that provides detailed information about the sessions running on your SQL Server instance. It is a great tool when we need to troubleshoot some problems such as long-running queries or blocking. (just two examples)
This stored procedure works on any version/edition since SQL Server 2005 SP1.
