所用内存百分比

Microsoft.Windows.Server.10.0.OperatingSystem.PercentMemoryUsed.Collection (Rule)

此规则收集关于使用的物理内存的数据。

Knowledge Base article:

摘要

此规则计算并收集 Memory\Available Mbytes 计数器与可用于系统的总物理内存的比率（百分比）。 系统会在视图和报表中收集和公开此信息。

Memory\Available Mbytes 计数器测量可供使用的物理 RAM 的量。 当 Available Mbytes 低时，系统将更加主动地向磁盘进行内存分页，当发生此操作时，可能会对总体系统性能有负面影响。
