SQL Server内部在执行一些特定的操作时,会和Disk做读写交互,这也会影响物理硬盘响应SQL Server的IO请求的性能,使查询进程处于PageIOLatch或WriteLog等待。 一,在系统级别监控物理Disk的IO性能 1,监控物理Disk的IO延迟 在Windows级别上对Physical Disk的IO延迟进行分析,主要依赖于Performance Monitor的计数器,衡量物理Disk...
Performance Monitor是一个系统内置的MMC控制台: 包括系统监视器(System Monitor)和性能日志和警报(Performance Logs and Alerts)两个部分.通过实时和日志的方式来记录服务器性能. 使用系统监视器可以取现, 曲方图或者报表的方式实时查看内存, 硬盘, 处理器, 网络等各种对象的性能数据. 使用性能日志也警报可以对计数器...
Performance Monitor uses remote procedure calls (RPCs) to collect information from Microsoft SQL Server. Any user who has Microsoft Windows permissions to run Performance Monitor can use Performance Monitor to monitor SQL Server.As with all performance monitoring tools, expect some performance overhead ...
If you are running Microsoft Windows server operating system, use the Performance Monitor graphical tool to measure the performance of SQL Server. You can view SQL Server objects, performance counters, and the behavior of other objects, such as processors, memory, cache, threads, and processes. ...

SQL Server的IO性能受到物理Disk的IO延迟和SQL Server内部执行的IO操作的影响。在监控Disk性能时,最主要的度量值(metric)是IO延迟,IO延迟是指从Application创建IO请求,到Disk完成IO请求的时间延迟。如果物理Disk不能及时完成IO请求,跟不上请求负载的速度,那么SQL Server就容易出现性能问题。SQL Server内部在执行一些特定...
