一、 创建一张表用于存放抓取到的Running SQL

USE[dba_monitor]
GO
CREATETABLE[running_sql_monitor](
[id][int]IDENTITY(1,1) NOTNULLPRIMARYKEY,
[Insert_Time][datetime]NOTNULLDEFAULT (getdate()),
[Start_Time][datetime]NOTNULL,
[R_S][int]NULL,
[session_id][smallint]NOTNULL,
[status][nvarchar](30) NOTNULL,
[wait_type][nvarchar](60) NULL,
[wait_resource][nvarchar](256) NOTNULL,
[wait_time][int]NOTNULL,
[cpu_cnt][int]NULL,
[b_spid][smallint]NULL,
[dbname][nvarchar](128) NULL,
[t_level][smallint]NOTNULL,
[o_t_c][int]NOTNULL,
[row_count][bigint]NOTNULL,
[parent_query][nvarchar](max) NULL,
[individual_query][nvarchar](max) NULL,
[QueryPlan_XML][xml]NULL,
[login_name][nvarchar](128) NOTNULL,
[host_name][nvarchar](128) NULL,
[program_name][nvarchar](128) NULL,
[client_interface_name][nvarchar](32) NULL,
[cpu_time][int]NOTNULL,
[logical_reads][bigint]NOTNULL,
[reads][bigint]NOTNULL,
[writes][bigint]NOTNULL,
[memory_usage][int]NULL,
[tempdb_user_objects_mb][int]NULL,
[tempdb_internal_objects_mb][int]NULL,
[login_time][datetime]NOTNULL,
[percent_complete][real]NOTNULL
) ON[PRIMARY]
GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘自增列‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘id‘

GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘SQL执行开始时间‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘Start_Time‘

GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘SQL使用的CPU核数‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘cpu_cnt‘
GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘被哪个session_id阻塞‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘b_spid‘

GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘SQL语句的执行计划‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘QueryPlan_XML‘
GO

GO
EXEC sys.sp_addextendedproperty @name=N‘MS_Description‘, @value=N‘SQL中的内部对象占用tempdb大小(单位MB)‘ , @level0type=N‘SCHEMA‘,@level0name=N‘dbo‘, @level1type=N‘TABLE‘,@level1name=N‘running_sql_monitor‘, @level2type=N‘COLUMN‘,@level2name=N‘tempdb_internal_objects_mb‘
GO

 

二、创建SQL Server JOB抓取Running SQL

JOB 每分钟运行一次

 

job step1、 抓取Running SQL

INSERTINTO dba_monitor..running_sql_monitor(
Start_Time, R_S, session_id, [status], wait_type, wait_resource, wait_time, cpu_cnt, b_spid, DBNAME, t_level, o_t_c, row_count, 
parent_query, individual_query, QueryPlan_XML, login_name, [host_name], [program_name], client_interface_name, cpu_time, logical_reads, reads, writes,
memory_usage, tempdb_user_objects_mb, tempdb_internal_objects_mb, login_time, percent_complete
 )
SELECT  r.start_time, r.total_elapsed_time/1000AS R_S, r.session_id,
        r.[status], r.wait_type, r.wait_resource,r.wait_time,
        x.counts AS cpu_cnt ,r.blocking_session_id AS b_spid,  
DB_NAME(r.database_id) AS dbname,
        es.transaction_isolation_level AS t_level,r.open_transaction_count AS o_t_c, es.row_count,
        parent_query = qt.[text], 
        individual_query =SUBSTRING(qt.[text], (r.statement_start_offset /2) +1,((CASEWHEN r.statement_end_offset =-1THENLEN(CONVERT(NVARCHAR(MAX), qt.[text])) *2
ELSE r.statement_end_offset END- r.statement_start_offset) /2) +1), 
        QueryPlan_XML = (SELECT query_plan FROM  sys.dm_exec_query_plan(r.plan_handle)),
        es.login_name, es.host_name, es.program_name, es.client_interface_name,
        r.cpu_time, r.logical_reads, r.reads, r.writes, memory_usage,
        (su.user_objects_alloc_page_count *8/1024) AS tempdb_user_objects_mb, 
        (su.internal_objects_alloc_page_count *8/1024) AS tempdb_internal_objects_mb,
        es.login_time, r.percent_complete       
FROM    sys.dm_exec_requests AS r WITH(NOLOCK)
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS qt
INNERJOIN sys.dm_exec_sessions AS es WITH(NOLOCK) ON r.session_id = es.session_id
LEFTJOIN (SELECT spid,MAX(loginame)AS loginame,COUNT(0)AS counts FROM sys.sysprocesses WITH(NOLOCK) GROUPBY spid)  x ON x.spid=r.session_id
LEFTJOIN sys.dm_db_session_space_usage su on es.session_id=su.session_id
WHERE  es.is_user_process =1
AND es.session_Id <>@@SPID

 

job step2、为防止监控表过大，删除7天前抓取到的数据

deletetop(100) from  dba_monitor..running_sql_monitor where InsertTime <DATEADD(DAY, -7, CAST(GETDATE() as DATE))
