Getting SQL Server Activity Monitor's Output using t-SQL - sql-server

Question

How to get the SQL Server Activity Monitor's output using T-SQL???

Answer 1

In order to get exactly same output as Activity Monitor; I have created a following script.
If you use this script, you don't need sp_who2 or activity monitor to run.
The script that I have created 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.
[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]
My Activity Monitor's Script is as follows:
/* ACTIVITY MONITOR'S OUTPUT along with statement_text and command_text */ /* Processes */
SELECT [Session ID] = s.session_id,
[User Process] = CONVERT(CHAR(1), s.is_user_process),
[Login] = s.login_name,
[Blocked By] = ISNULL(CONVERT (varchar, w.blocking_session_id), ''),
[Head Blocker] =
CASE
-- session has an active request, is blocked, but is blocking others or session is idle but has an open tran and is blocking others
WHEN r2.session_id IS NOT NULL AND (r.blocking_session_id = 0 OR r.session_id IS NULL) THEN '1'
-- session is either not blocking someone, or is blocking someone but is blocked by another party
ELSE ''
END,
[DatabaseName] = ISNULL(db_name(r.database_id), N''),
[Task State] = ISNULL(t.task_state, N''),
[Command] = ISNULL(r.command, N''),
[statement_text] = Substring(st.TEXT, (r.statement_start_offset / 2) + 1,
( ( CASE r.statement_end_offset WHEN - 1 THEN Datalength(st.TEXT)
ELSE r.statement_end_offset
END - r.statement_start_offset ) / 2 ) + 1), ----It will display the statement which is being executed presently.
[command_text] =Coalesce(Quotename(Db_name(st.dbid)) + N'.' + Quotename(Object_schema_name(st.objectid, st.dbid)) + N'.' + Quotename(Object_name(st.objectid, st.dbid)), ''), -- It will display the Stored Procedure's Name.
[Total CPU (ms)] = r.cpu_time,
r.total_elapsed_time / (1000.0) 'Elapsed Time (in Sec)',
[Wait Time (ms)] = ISNULL(w.wait_duration_ms, 0),
[Wait Type] = ISNULL(w.wait_type, N''),
[Wait Resource] = ISNULL(w.resource_description, N''),
[Total Physical I/O (MB)] = (s.reads + s.writes) * 8 / 1024,
[Memory Use (KB)] = s.memory_usage * 8192 / 1024,
--[Open Transactions Count] = ISNULL(r.open_transaction_count,0),
--[Login Time] = s.login_time,
--[Last Request Start Time] = s.last_request_start_time,
[Host Name] = ISNULL(s.host_name, N''),
[Net Address] = ISNULL(c.client_net_address, N''),
-- [Execution Context ID] = ISNULL(t.exec_context_id, 0),
-- [Request ID] = ISNULL(r.request_id, 0),
[Workload Group] = N'',
[Application] = ISNULL(s.program_name, N'')
FROM sys.dm_exec_sessions s
LEFT OUTER JOIN sys.dm_exec_connections c ON (s.session_id = c.session_id)
LEFT OUTER JOIN sys.dm_exec_requests r ON (s.session_id = r.session_id)
LEFT OUTER JOIN sys.dm_os_tasks t ON (r.session_id = t.session_id
AND r.request_id = t.request_id)
LEFT OUTER JOIN
( -- In some cases (e.g. parallel queries, also waiting for a worker), one thread can be flagged as
-- waiting for several different threads. This will cause that thread to show up in multiple rows
-- in our grid, which we don't want. Use ROW_NUMBER to select the longest wait for each thread,
-- and use it as representative of the other wait relationships this thread is involved in.
SELECT *,
ROW_NUMBER() OVER (PARTITION BY waiting_task_address
ORDER BY wait_duration_ms DESC) AS row_num
FROM sys.dm_os_waiting_tasks ) w ON (t.session_id = w.session_id)

LEFT OUTER JOIN sys.dm_exec_requests r2 ON (r.session_id = r2.blocking_session_id) OUTER APPLY sys.dm_exec_sql_text(r.sql_handle) AS st
WHERE s.session_Id > 50 -- Ignore system spids.
ORDER BY s.session_id --,[Total CPU (ms)] desc ;

Not exactly sure what you are looking for, but this should give you something similar what you see on the activity monitor (not completely but similar).
SELECT
P.spid,
RIGHT(CONVERT(VARCHAR, DATEADD(MS, DATEDIFF(MS, P.last_batch, GETDATE()), '1900-01-01'), 121), 12) AS [BATCH_DURATION],
P.program_name,
P.hostname AS HOST_NAME,
P.loginame AS LOGIN_NAME
FROM master.dbo.sysprocesses AS P
WHERE
P.spid > 50 AND
P.status NOT IN ('background', 'sleeping') AND
P.cmd NOT IN
(
'AWAITING COMMAND',
'MIRROR HANDLER',
'LAZY WRITER',
'CHECKPOINT SLEEP',
'RA MANAGER'
)
ORDER BY 2
The reason we are looking for SPID > 50 is because processes that has ID smaller than 50 belongs to internal operations. Anything greater than 50 should be for user actions.
Also, you can see all the blockings etc. on a db, you could try something like this.
SELECT
db.name AS DB_NAME,
tl.request_session_id AS REQUESTING_SESSION,
wt.blocking_session_id AS BLOCKING_SESSION,
OBJECT_NAME(p.OBJECT_ID) AS BLOCKED_OBJECT,
tl.resource_type AS RESOURCE_TYPE,
h1.TEXT AS REQUEST_QUERY,
h2.TEXT AS BLOCKING_QUERY,
tl.request_mode
FROM sys.dm_tran_locks AS tl
INNER JOIN sys.databases db ON db.database_id = tl.resource_database_id
INNER JOIN sys.dm_os_waiting_tasks AS wt ON tl.lock_owner_address = wt.resource_address
INNER JOIN sys.partitions AS p ON p.hobt_id = tl.resource_associated_entity_id
INNER JOIN sys.dm_exec_connections ec1 ON ec1.session_id = tl.request_session_id
INNER JOIN sys.dm_exec_connections ec2 ON ec2.session_id = wt.blocking_session_id
CROSS APPLY sys.dm_exec_sql_text(ec1.most_recent_sql_handle) AS h1
CROSS APPLY sys.dm_exec_sql_text(ec2.most_recent_sql_handle) AS h2
You can possibly combine these to get what exactly you are looking for.
Hope this helps.
