Total Processor \% DPC Time (SUSE Linux Enterprise Server 12)

Microsoft.Linux.SLES.12.OperatingSystem.TotalPercentDPCTime.Collection (Rule)

收集效能計數器 Processor\\% DPC Time

Knowledge Base article:

摘要

此規則收集 [Processor\% DPC Time (_Total)] 效能計數器的效能資料。您可以在效能檢視和報表中存取收集的值。

此標準會以百分比顯示所有處理器花費在接收與處理延遲程序呼叫 (DPC) 的時間。DPC 是一種插斷，它的執行優先順序比標準插斷低。% DPC Time 是 % Privileged Time 的元件，因為 DPC 是以特殊權限模式執行。如果 [% DPC Time] 持續偏高，表示可能發生處理器瓶頸，或者發生可能致使整體系統效能顯著降低的應用程式或硬體相關問題。

代理程式傳回的值是在 1 分鐘的間隔內查詢的 5 個最新值的彙總平均。
