摘要

此规则收集 Memory\Page Reads/sec 性能计数器的性能数据。

Physical Disk\Pages Reads/sec 性能计数器显示为解决强制分页错误而读取磁盘的速率。它显示读取操作的数目，不考虑在每个操作中搜索的页数。如果进程调用虚拟内存中不在工作集内或物理内存的某处的页面，而从磁盘中检索此页面，将发生硬页面错误。此计数器是导致系统范围延迟的错误种类的主要指示器。它包括用于解决文件系统缓存（通常由应用程序请求）和非缓存映射内存文件中的错误的读取操作。对比 Memory\Pages Reads/sec 的值与 Memory\Pages Input/sec 的值以确定每次操作期间读取的平均页面数。
