SQL Server Current Activity SuperCheck

,

This gives a quick check of the current activity on a SQL Server. I developed this after getting continually frustrated with "Current Activity" in SQL/EM getting blocked by processes when I needed to see blocking issues on the server. It has been immensely valuable to me in quickly identifying production-stopping issues on the database.

It works best using a grid view. It will display all connections that are active or have open transactions (although this is easily adjustable). The niftiest part, though, it that it shows the active command text (DBCC INPUTBUFFER) for each SPID.

SET NOCOUNT ON

Purpose:
Identify active or blocking connections, and list the active command on the connection.

/*
Status Definitions, per Books Online:

Background	SPID is performing a background task. 
Sleeping	SPID is not currently executing. This usually indicates that the SPID is awaiting a command from the application. 
Runnable	SPID is currently executing. 
Dormant  	Same as Sleeping, except Dormant also indicates that the SPID has been reset after completing an RPC event. The reset cleans up resources used during the RPC event. This is a normal state and the SPID is available and waiting to execute further commands.  
Rollback	The SPID is in rollback of a transaction. 
Defwakeup	Indicates that a SPID is waiting on a resource that is in the process of being freed. The waitresource field should indicate the resource in question. 
Spinloop	Process is waiting while attempting to acquire a spinlock used for concurrency control on SMP systems
