邏輯磁碟閒置時間百分比

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

監視效能計數器 LogicalDisk\\% Idle Time

摘要

邏輯磁碟上發生許多活動，導致閒置時間百分比低於多個連續範例的閾值。

原因

邏輯磁碟最近曾發生活動大幅增加的情況，而且此驟增情況導致活動量超過閾值，或是邏輯磁碟的使用率隨著時間穩定增加，最後達到超過閾值的程度。

另一個可能的原因是基礎實體磁碟或磁碟子系統的某些部分發生問題或設定不正確，因而影響到邏輯磁碟的效能。

解決方式

若要進一步調查此問題，請考慮採用下列方法：

根據進一步調查的結果，解決方式可能有所不同且可能包括下列其中一種：
