使用t-SQL获取SQL Server活动监视器的输出

Question

如何使用T-SQL获取SQL Server活动监视器的输出？

Answer 1

为了获得与活动监视器完全相同的输出;我创建了一个以下脚本。

如果使用此脚本，则不需要运行sp_who2或活动监视器。

我创建将显示以下事物的脚本：

• [会话ID]
• [用户处理]
• [注册]
• [阻塞者]
• [Head Blocker]
• [DatabaseName]
• [任务状态]
• [命令]
• [statement_text] - 它将显示当前正在执行的语句。
• [command_text] -----它将显示存储过程的名称。
• [总CPU（毫秒）]
• '经过时间（以秒为单位）'
• [等待时间（毫秒）]
• [等待类型]
• [等待资源]
• [存储器使用（KB）
• [主机名]
• [网络地址]
• [工作量组]
• [应用]

我的动态监控的脚本如下：

/* 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''), 
[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'')

             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.

WHERE s.session_Id > 50 -- Ignore system spids. 

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

不完全确定你在找什么，但是这应该给你类似于你在活动监视器上看到的东西（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 

我们正在寻找SPID > 50的原因是因为有ID小于50的过程属于内部操作。任何大于50的应该是用户操作。另外，你可以在数据库中看到所有的阻塞等，你可以尝试这样的事情。

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 

你可以结合这些来得到你正在寻找什么。 希望这有助于。
