将数据库中所有表的所有的内容选一遍:
IF object_id('tempdb..#temp') is not null
BEGIN DROP TABLE #temp ENDDECLARE @index int
DECLARE @count int DECLARE @schemaname varchar(50) DECLARE @tablename varchar(50) set @index=1 set @count=(select count(*) from sysobjects where xtype='U')select row_number() over(order by name) as rowNumber,name,
( SELECT a.name from sys.tables t inner join sys.schemas a ON t.schema_id=a.schema_id WHERE t.name=ob.name) as schemaname into #temp from sysobjects ob where xtype='U'WHILE(@index<@count)
BEGIN set @schemaname=(SELECT schemaname from #temp where rowNumber=@index) set @tablename=(SELECT name from #temp where rowNumber=@index)exec('select * from '+ @schemaname+'.'+@tablename)
set @index=@index+1
END
通常来说，需要看如下几个计数器（下面资料参考自）:
- Memory: Pages/sec
- Memory: Available Bytes
- Network Interface: Bytes Total/Sec
- Physical Disk: % Disk time
- Physical Disk: Avg. Disk Queue Length
- Processor: % Processor Time
- System: Processor Queue Length
- SQL Server Buffer: Buffer Cache Hit Ratio
- SQL Server General: User Connections
Memory: Pages/sec:最好不要大于5，否则有内存问题
Memory: Available Bytes :这个可以望文生义，不解释
Network Interface: Bytes Total/Sec :如果这个计数器下降的太快有可能是网络出现问题
Physical Disk: Avg Disk Queue Length:每个物理盘的等待队列，大于2有可能是IO瓶颈问题
Physical Disk: % Disk time: 读/写活动的百分比，不要大于90%,和上面的计数器一起可以显示IO瓶颈
Processor: % Processor Time :CPU瓶颈，不要大于90%，大多数情况下，内存和IO瓶颈要更多
System: Processor Queue Length :同样，和上面计数器一起找出IO瓶颈
SQL Server Buffer: Buffer Cache Hit Ratio :缓存命中率，不要低于85%,否则考虑加内存
SQL Server General:并发数,压测时快到某一瓶颈看看这个数字，可以作为基准(BaseLine)记下来
