使用t-SQL獲取SQL Server活動監視器的輸出

Question

如何使用T-SQL獲取SQL Server活動監視器的輸出？

Answer 1

爲了獲得與活動監視器完全相同的輸出;我創建了一個以下腳本。

如果使用此腳本，則不需要運行sp_who2或活動監視器。

我創建將顯示以下事物的腳本：

• [會話ID]
• [用戶處理]
• [註冊]
• [阻塞者]
• [Head Blocker]
• [DatabaseName]
• [任務狀態]
• [命令]
• [statement_text] - 它將顯示當前正在執行的語句。
• [command_text] -----它將顯示存儲過程的名稱。
• [總CPU（毫秒）]
• '經過時間（以秒爲單位）'
• [等待時間（毫秒）]
• [等待類型]
• [等待資源]
• [存儲器使用（KB）
• [主機名]
• [網絡地址]
• [工作量組]
• [應用]

我的動態監控的腳本如下：

/* 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)] = s.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''),

        [Application] = ISNULL(s.program_name, N'')

LEFT OUTER JOIN 
    (-- In some cases (e.g. parallel queries, also waiting for a worker), one thread can be flagged as

ORDER BY s.session_id --,[Total CPU (ms)] desc ;

不完全確定你在找什麼，但是這應該給你類似於你在活動監視器上看到的東西（不完全但相似）。

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 

我們正在尋找SPID > 50的原因是因爲有ID小於50的過程屬於內部操作。任何大於50的應該是用戶操作。另外，你可以在數據庫中看到所有的阻塞等，你可以嘗試這樣的事情。

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 

你可以結合這些來得到你正在尋找什麼。 希望這有助於。
