物理逻辑磁盘空闲时间百分比

Microsoft.Windows.Server.2008.PhysicalDisk.PercentIdleTime (UnitMonitor)

监视性能计数器 PhysicalDisk\\% Idle Time

Knowledge Base article:

摘要

物理磁盘上发生了许多活动，因此空闲时间百分比已低于多个连续采样的阈值。

原因

物理磁盘最近出现活动大量增加的现象，此最大值导致超出了阈值，或者物理磁盘的使用率随着时间的推移稳定增大，并且最终达到一个超出阈值的点。

另一种可能就是基本物理磁盘或磁盘子系统的某个部分运行不正常或配置不正确，从而降低了物理磁盘的性能。

解决方法

要进一步调查此问题，请考虑：

根据进一步的调查结果，解决方案可能会有所不同，并且可能包含以下其中一项：
