摘要

此規則會收集 Memory\Page Reads/sec 效能計數器的效能資料。

Physical Disk\Pages Reads/sec 效能計數器會顯示為解決硬體分頁錯誤而讀取磁碟的速率。這會顯示讀取作業的次數，而不考慮每次作業所擷取的頁數。當處理程序參照的虛擬記憶體分頁不在實體記憶體中的工作集或其他位置，因而必須從磁碟進行擷取時，就會發生硬體分頁錯誤。此計數器是導致整個系統延遲這類錯誤的主要指示器。它包含為解決檔案系統快取中的錯誤 (通常是由應用程式要求)，以及未快取的記憶體對應檔案中的錯誤而執行的讀取操作。將 Memory\Pages Reads/sec 的值與 Memory\Pages Input/sec 的值做比較，以確定每次作業中讀取的平均分頁數。
