如何使用T-SQL获取SQL Server活动监视器的输出???

Answer 1

不完全确定你在寻找什么，但这应该会给你一些类似你在活动监视器上看到的东西（不是完全但类似的）。

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

我们寻找SPID > 50的原因是因为ID小于50的进程属于内部操作。任何大于50的内容都应该是用户操作。

另外，你可以看到db上的所有阻塞等，你可以试试这样的东西。

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

您可以将这些结合起来以获得您正在寻找的内容。希望这会有所帮助。

为了获得与Activity Monitor完全相同的输出;我创建了以下脚本。

如果您使用此脚本，则无需运行sp_who2或活动监视器。

我创建的脚本将显示以下内容：

[会话ID]
[用户流程]
[登录]
[被阻止]
[Head Blocker]
[数据库名]
[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（ms）]
'经过时间（以秒为单位）'
[等待时间（毫秒）]
[等待类型]
[等待资源]
[内存使用（KB）]
[主机名]
[网址]
[工作量组]
[应用]

我的活动监视器的脚本如下：

/* 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.
