Find currently running session/process in SQL Server database/instance with help of sys.dm_exec_requests and sys.dm_exec_sessions

As a DBA, it is mandatory to keep an eye on your database and server too, especially during the business hour. SQL Server providing very helpful Dynamic Management View to help in this situation. Dynamic Management View (DMV) are as follow:


I have created one SQL Server view with the help of following script which I used to use, often, during business hours to check whether everything is going smooth or not.


OBJECT_NAME(objectid) as ObjectName
,SUBSTRING(stateText.text, (statement_start_offset/2)+1,
((CASE statement_end_offset
WHEN -1 THEN DATALENGTH(stateText.text)
ELSE statement_end_offset
END - statement_start_offset)/2) + 1) AS statement_text
,DB_Name(database_id) as DatabaseName
,req.cpu_time AS CPU_Time
,DATEDIFF(minute, last_request_start_time, getdate()) AS RunningMinutes
,sess.HOST_NAME as RunningFrom
,sess.session_id AS SessionID
,req.blocking_session_id AS BlockingWith

sys.dm_exec_requests req
INNER JOIN sys.dm_exec_sessions sess ON sess.session_id = req.session_id
AND sess.is_user_process = 1
sys.dm_exec_sql_text(sql_handle) AS stateText

Now, whenever I want to see the status whether anything is blocking to my query/queries or which query/SP is being executed from which time. How many reads/writes happening by each objects. if there is a task like backup/restore, I can even see, how many percent complete by just executing one simple SELECT statement:



If you wish you can, even, use this VIEW in your .NET web page/windows application so that you don’t even need to connect to database directly to see the status.

    I was just seeking this information for a while. After 6 hours of continuous Googleing, at last I got it in your website. I wonder what’s the lack of Google strategy that don’t rank this type of informative websites in top of the list. Normally the top web sites are full of garbage.
