1、锁监控
查看锁住的表：
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName from sys.dm_tran_locks where resource_type=‘OBJECT‘
查看哪个会话引起阻塞并且它们在运行什么：
SELECT DTL.[request_session_id] AS [session_id] , DB_NAME(DTL.[resource_database_id]) AS [Database] , DTL.resource_type , CASE WHEN DTL.resource_type IN ( ‘DATABASE‘, ‘FILE‘, ‘METADATA‘ ) THEN DTL.resource_type WHEN DTL.resource_type = ‘OBJECT‘ THEN OBJECT_NAME(DTL.resource_associated_entity_id, DTL.[resource_database_id]) WHEN DTL.resource_type IN ( ‘KEY‘, ‘PAGE‘, ‘RID‘ ) THEN ( SELECT OBJECT_NAME([object_id]) FROM sys.partitions WHERE sys.partitions.hobt_id = DTL.resource_associated_entity_id ) ELSE ‘Unidentified‘ END AS [Parent Object] , DTL.request_mode AS [Lock Type] , DTL.request_status AS [Request Status] , DER.[blocking_session_id] , DES.[login_name] , CASE DTL.request_lifetime WHEN 0 THEN DEST_R.TEXT ELSE DEST_C.TEXT END AS [Statement] FROM sys.dm_tran_locks DTL LEFT JOIN sys.[dm_exec_requests] DER ON DTL.[request_session_id] = DER.[session_id] INNER JOIN sys.dm_exec_sessions DES ON DTL.request_session_id = DES.[session_id] INNER JOIN sys.dm_exec_connections DEC ON DTL.[request_session_id] = DEC.[most_recent_session_id] OUTER APPLY sys.dm_exec_sql_text(DEC.[most_recent_sql_handle]) AS DEST_C OUTER APPLY sys.dm_exec_sql_text(DER.sql_handle) AS DEST_R WHERE DTL.[resource_database_id] = DB_ID() AND DTL.[resource_type] NOT IN ( ‘DATABASE‘, ‘METADATA‘ ) ORDER BY DTL.[request_session_id];
查看因为单条UPDATE语句锁住的用户表：

3、数据库环境监控
查询当前数据库的配置信息：
Select configuration_id ConfigurationId, name Name, description Description, Cast(value as int) value, Cast(minimum as int) Minimum, Cast(maximum as int) Maximum, Cast(value_in_use as int) ValueInUse, is_dynamic IsDynamic, is_advanced IsAdvanced From sys.configurations Order By is_advanced, name
检查SQL SERVER 当前已创建的线程数：
select count(*) from sys.dm_os_workers
查询当前连接到数据库的用户信息：
Select s.login_name LoginName, s.host_name HostName, s.transaction_isolation_level TransactionIsolationLevel, Max(c.connect_time) LastConnectTime, Count(*) ConnectionCount, Sum(Cast(c.num_reads as BigInt)) TotalReads, Sum(Cast(c.num_writes as BigInt)) TotalWrites From sys.dm_exec_connections c Join sys.dm_exec_sessions s On c.most_recent_session_id = s.session_id Group By s.login_name, s.host_name, s.transaction_isolation_level
查询CPU和内存利用率：
Select DateAdd(s, (timestamp - (osi.cpu_ticks / Convert(Float, (osi.cpu_ticks / osi.ms_ticks)))) / 1000, GETDATE()) AS EventTime, Record.value(‘(./Record/SchedulerMonitorEvent/SystemHealth/SystemIdle)[1]‘, ‘int‘) as SystemIdle, Record.value(‘(./Record/SchedulerMonitorEvent/SystemHealth/ProcessUtilization)[1]‘, ‘int‘) as ProcessUtilization, Record.value(‘(./Record/SchedulerMonitorEvent/SystemHealth/MemoryUtilization)[1]‘, ‘int‘) as MemoryUtilization From (Select timestamp, convert(xml, record) As Record From sys.dm_os_ring_buffers Where ring_buffer_type = N‘RING_BUFFER_SCHEDULER_MONITOR‘ And record Like ‘%<SystemHealth>%‘) x Cross Join sys.dm_os_sys_info osi Order By timestamp
查看每个数据库缓存大小：
SELECT COUNT(*) * 8 / 1024 AS ‘Cached Size (MB)‘ , CASE database_id WHEN 32767 THEN ‘ResourceDb‘ ELSE DB_NAME(database_id) END AS ‘Database‘ FROM sys.dm_os_buffer_descriptors GROUP BY DB_NAME(database_id) , database_id ORDER BY ‘Cached Size (MB)‘ DESC
统计IO活动信息：
SET STATISTICS IO ON select top 10* from Table SET STATISTICS IO OFF
清除缓存SQL语句：
CHECKPOINT; GO DBCC FREEPROCCACHE ---清空执行计划缓存 DBCC DROPCLEANBUFFERS; --清空数据缓存 GO
查看当前进程的信息：
DBCC INPUTBUFFER(51)
查看当前数据是否启用了快照隔离：
DBCC USEROPTIONS;
查看摸个数据库数据表中的数据页类型：
--In_Row_Data: 分别为存储行内数据的 --LOB_Data: 存储Lob对象,Lob对象用于存储存在数据库的二进制文件 --当这个类型的列出现时,原有的列会存储一个24字节的指针，而将具体的二进制数据存在LOB页中 --Row_Overflow_data:存储溢出数据的,使用Varchar,nvarchar等数据类型时，当行的大小不超过8060字节时，全部存在行内In-row data --当varchar中存储的数据过多使得整行超过8060字节时，会将额外的部分存于Row-overflow data页中， --如果update这列使得行大小减少到小于8060字节，则这行又会全部回到in-row data页 --text,ntext和image类型来说，每一列只要不为null,即使占用很小的数据，也需要额外分配一个LOB页 DBCC IND ( Lawyer, [dbo.tb_Contract], -1)
4、sql执行次数和性能监控
查询CPU最高的10条SQL：
SELECT TOP 10 TEXT AS ‘SQL Statement‘ ,last_execution_time AS ‘Last Execution Time‘ ,(total_logical_reads + total_physical_reads + total_logical_writes) / execution_count AS [Average IO] ,(total_worker_time / execution_count) / 1000000.0 AS [Average CPU Time (sec)] ,(total_elapsed_time / execution_count) / 1000000.0 AS [Average Elapsed Time (sec)] ,execution_count AS "Execution Count",qs.total_physical_reads,qs.total_logical_writes ,qp.query_plan AS "Query Plan" FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.plan_handle) st CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY total_elapsed_time / execution_count DESC
找出执行频繁的语句的SQL语句：
with aa as ( SELECT --执行次数 QS.execution_count, --查询语句 SUBSTRING(ST.text,(QS.statement_start_offset/2)+1, ((CASE QS.statement_end_offset WHEN -1 THEN DATALENGTH(st.text) ELSE QS.statement_end_offset END - QS.statement_start_offset)/2) + 1 ) AS statement_text, --执行文本 ST.text, --执行计划 qs.last_elapsed_time, qs.min_elapsed_time, qs.max_elapsed_time, QS.total_worker_time, QS.last_worker_time, QS.max_worker_time, QS.min_worker_time FROM sys.dm_exec_query_stats QS --关键字 CROSS APPLY sys.dm_exec_sql_text(QS.sql_handle) ST WHERE QS.last_execution_time > ‘2016-02-14 00:00:00‘ and execution_count > 500 -- AND ST.text LIKE ‘%%‘ --ORDER BY --QS.execution_count DESC ) select text,max(execution_count) execution_count --,last_elapsed_time,min_elapsed_time,max_elapsed_time from aa where [text] not like ‘%sp_MSupd_%‘ and [text] not like ‘%sp_MSins_%‘ and [text] not like ‘%sp_MSdel_%‘ group by text order by 2 desc
查找逻辑读取最高的查询(存储过程)：
SELECT TOP ( 25 ) P.name AS [SP Name] , Deps.total_logical_reads AS [TotalLogicalReads] , deps.total_logical_reads / deps.execution_count AS [AvgLogicalReads] , deps.execution_count , ISNULL(deps.execution_count / DATEDIFF(Second, deps.cached_time, GETDATE()), 0) AS [Calls/Second] , deps.total_elapsed_time , deps.total_elapsed_time / deps.execution_count AS [avg_elapsed_time] , deps.cached_time FROM sys.procedures AS p INNER JOIN sys.dm_exec_procedure_stats AS deps ON p.[Object_id] = deps.[Object_id] WHERE deps.Database_id = DB_ID() ORDER BY deps.total_logical_reads DESC;
查看某个SQL的执行计划：
SET STATISTICS PROFILE ON SELECT * FROM Demo SET STATISTICS PROFILE OFF
查询某个SQL的执行时间：
SET STATISTICS Time ON SELECT * FROM Demo SET STATISTICS TIME OFF
查询某个SQL的IO信息：
SET STATISTICS IO ON SELECT * FROM Demo SET STATISTICS IO OFF
5、开源监控脚本，监控数据库锁定情况
