監視邏輯 CPU 插斷時間百分比

Knowledge Base article:

摘要

邏輯處理器的 % Interrupt Time (Processor Information\% Interrupt Time) 已超過閾值。整體系統效能可能會明顯下降,進而造成作業系統與應用程式效能不良。

% Interrupt Time 是邏輯處理器在取樣間隔期間花費在接收與處理硬體插斷的時間。此值是產生插斷的裝置 (如系統時鐘、滑鼠、磁碟驅動程式、資料通訊線路、網路介面卡及其他週邊裝置) 活動的間接指示器。當這些裝置完成工作或有需求時,通常會對處理器發出插斷。

原因

% Interrupt Time 過高通常表示硬體裝置發生問題。
