【MSSQL】获得客户端详细信息以及每个进程

作者:yangzhawen / 发布于2012/2/21/ 577

db性能下降时很多朋友都想监控到是哪个客户端、哪个用户、哪台客户端发起的什么会话sql语句，但是微软自带的要使用profiler才能实现，但是考虑性能问题，很多人不愿意！

<div>--1.新建存储过程
--create   proc   prtest 
<a href="mailto:--@spid">--@spid</a>   int 
--as 
--dbcc   inputbuffer   (@spid) 
--go
--2.将结果保存到临时变量#tmp
SELECT  [Session ID] AS 会话ID ,
[Login] AS 用户名 ,
[Database] AS 数据库 ,
[Task State] AS 状态 ,
[Command] AS 命令 ,
[Application] AS 应用软件 ,
[Wait Time (ms)] AS 等待时间 ,
[Wait Type] AS 等待类型 ,
[Host Name] AS 客户机名 ,
[Net Address] AS IP地址  INTO #tmp

FROM    ( SELECT    [Session ID] = s.session_id ,
[User Process] = CONVERT(CHAR(1), s.is_user_process) ,
[Login] = s.login_name ,
[Database] = ISNULL(DB_NAME(p.dbid), N'') ,
[Task State] = ISNULL(t.task_state, N'') ,
[Command] = ISNULL(r.command, N'') ,
[Application] = ISNULL(s.program_name, N'') ,
[Wait Time (ms)] = ISNULL(w.wait_duration_ms, 0) ,
[Wait Type] = ISNULL(w.wait_type, N'') ,
[Wait Resource] = ISNULL(w.resource_description, N'') ,
[Blocked By] = ISNULL(CONVERT (VARCHAR, w.blocking_session_id),
'') ,
[Head Blocker] = CASE 
WHEN r2.session_id IS NOT NULL
AND ( r.blocking_session_id = 0
OR r.session_id IS NULL
) THEN '1' 
ELSE ''
END ,
[Total CPU (ms)] = s.cpu_time ,
[Total Physical I/O (MB)] = ( s.reads + s.writes ) * 8
/ 1024 ,
[Memory Use (KB)] = s.memory_usage * 8192 / 1024 ,
[Open Transactions] = 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] = ISNULL(g.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 (
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.task_address = w.waiting_task_address )
AND w.row_num = 1
LEFT OUTER JOIN sys.dm_exec_requests r2 ON ( s.session_id = r2.blocking_session_id )
LEFT OUTER JOIN sys.dm_resource_governor_workload_groups g ON ( g.group_id = s.group_id )
LEFT OUTER JOIN sys.sysprocesses p ON ( s.session_id = p.spid )
) t
WHERE   t.Command IN ( 'SELECT', 'UPDATE', 'DELETE' )

--3.创建保存结果的临时表
CREATE TABLE #jttest(
[会话ID] [smallint] NOT NULL,
[用户名] [nvarchar](128) NOT NULL,
[数据库] [nvarchar](128) NOT NULL,
[状态] [nvarchar](60) NOT NULL,
[命令] [nvarchar](16) NOT NULL,
[应用软件] [nvarchar](128) NOT NULL,
[等待时间] [bigint] NOT NULL,
[等待类型] [nvarchar](60) NOT NULL,
[客户机名] [nvarchar](128) NOT NULL,
[IP地址] [varchar](48) NOT NULL,
[TSQL] [varchar](4000) NULL
)
--4.将#tmp中值导入到临时表变量#jttest
INSERT INTO #jttest
([会话ID]
,[用户名]
,[数据库]
,[状态]
,[命令]
,[应用软件]
,[等待时间]
,[等待类型]
,[客户机名]
,[IP地址]
)
SELECT 

[会话ID]
,[用户名]
,[数据库]
,[状态]
,[命令]
,[应用软件]
,[等待时间]
,[等待类型]
,[客户机名]
,[IP地址]
FROM #tmp
--5.获得每个spid对应的TSQL语句
create   table   #tmp01( 
EventType   nvarchar(100),    
Parameters   Int, 
EventInfo   nvarchar(max)   
) 
declare @cursid int   
declare cur cursor for select [会话ID] from #jttest
open cur
fetch next from cur into @cursid
while @@FETCH_STATUS=0
begin
insert   into   #tmp01   exec   prtest   @cursid
UPDATE #jttest SET TSQL=(SELECT EventInfo FROM #tmp01 )
WHERE 会话<a href="mailto:ID=@cursid">ID=@cursid</a>
truncate table  #tmp01
fetch next from cur into @cursid
end
close cur
deallocate cur
DROP TABLE #tmp01
--6.查看最终结果
SELECT * FROM #jttest
DROP TABLE #tmp
DROP TABLE #jttest

--dbcc   inputbuffer   (896)
</div>
