内存可用兆字节

Microsoft.Windows.Client.2000.OperatingSystem.MemoryAvailableMBytes.Collection (Rule)

收集性能计数器 Memory\Available MBytes

Knowledge Base article:

摘要

此规则收集 Memory\Available Mbytes 性能计数器的性能数据。收集此信息并显示一个或多个视图和/或报表。

Physical Disk\Pages Writes/sec 性能计数器显示可用于在计算机上运行的进程的物理内存（以 MB 计），而不是在 Memory\Available Bytes 中报告的字节。它是通过将 Zeroed、Free 和 Stand by 内存列表相加计算而来的。Free 内存已准备好使用；Zeroed 内存是填充了零以防止后来的进程查看先前进程使用的数据的内存页；Standby 内存是路由至磁盘时从进程的工作集（其物理内存）中除去但仍然可回调的内存。此计数器仅显示上次观察的值；该值不是平均值。
