物理Disk能够执行预读操作,操作系统将物理Disk上的数据预先加载到内存中,在SQL Server进程访问数据时,该数据已经存在于内存中了。虽然SQL Server申请了物理读操作,但是,BCHR的测量值没有体现物理读操作,这是因为,在SQL Server读取数据时,数据是存在于内存中的,SQL Server执行的是逻辑读操作。 推荐阅读《Great SQL Ser...

我们默认提供了 SQL Server Overview 大盘。 总览 在该panel 能看到 SQL Server 运行时需要重点关注的指标,在检查 SQL Server 状态时,首先查看总览中是否有异常状态,再检查具体的指标。 启动状态:绿色代表正常运行,红色代表异常运行 内存使用率:使用红黄绿颜色提示,内存使用率在 80% 以下时为绿色,80%～90% 为黄色...
在这个类图中,PerformanceMonitor类负责收集性能指标、分析数据并生成报告。Metric类包含各种性能指标的详细信息,而Report类则用于生成监视报告。通过这种结构,可以轻松扩展功能和增加新指标。 总结 SQL Server的性能监视是一个复杂而重要的任务。通过使用动态管理视图、监视关键性能指标,以及构建有效的性能监视系统,数据库管理...
