How to get the SQL Server Activity Monitor's output using T-SQL?
To get the exact output as Activity Monitor:


I have modified the given script as follows. You can play the activity monitor on one side and this script in another window and verify the output.

You can also view the currently running expensive queries by using this script and for that just need to do ORDER BY [Total CPU (ms)] desc.

This script will display the following things:


[Session ID]
[User Process]
[Login]
[Blocked By]
[Head Blocker]
[DatabaseName]
[Task State]
[Command]
[statement_text] --It will display the statement which is being executed presently and it can be from the SP or the normal T-sql .
[command_text] ----- It will display the Stored Procedure's Name.
[Total CPU (ms)]
'Elapsed Time (in Sec)'
[Wait Time (ms)]
[Wait Type]
[Wait Resource]
[Memory Use (KB)]
[Host Name]
[Net Address]
[Workload Group]
[Application]


You can also add or remove the columns whichever you need .

I have commented out some columns in the query, like: --[Open Transactions Count] = ISNULL(r.open_transaction_count,0), --[Login Time] = s.login_time, --[Last Request Start Time] = s.last_request_start_time, So if you want can also add or remove the columns as per your requirement and you can also filter out the data DatabaseName wise. I hope this script will help many of us.
