usp_ActiveProcesses - SQL 2k5

,

Returns list of active processes and their buffer contents (what they execute)
A process is considered as active if it has some changes of cpu time consumed or number of io operation in specified period.
Usage: EXEC usp_ActiveProcessesInput <SecondsDelay> -> Optional time interval to catch activity.

IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = Object_id(N'[dbo].[usp_ActiveProcesses]') AND Objectproperty(id,N'IsProcedure') = 1)
