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...
SQL Server和物理Disk进行IO交互的操作: 对于内存中没有缓存的数据,第一次访问时,需要将数据从数据文件读取到内存中,SQL Server访问的任何数据必须缓存到内存中,如果不在内存中,SQL Server发送读请求,将数据页从物理Disk读取到内存中,这个过程叫做物理读;如果数据存在于内存中,SQL Server直接访问,这个过程叫做逻辑读。

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...

Performance Monitor3:监控SQL Server的内存压力,SQLServer使用的资源受到操作系统的调度,同时,SQLServer在内部实现了一套调度算法,用于管理从操作系统获取的资源,主要是对内存和CPU资源的调度。一个好的数据库系统,必定在内存中缓存足够多的信息,以减少从物理硬盘
