收集效能計數器 Memory\Available MBytes

摘要

此規則收集 Memory\Available Mbytes 效能計數器的效能資料。此資訊會收集並公開在一或多個檢視及/或報表中。

Physical Disk\Pages Writes/sec 效能計數器會以 MB 顯示可供電腦上執行的程序使用的實體記憶體容量，而非 Memory\Available Byte 中報告的位元組。其計算方式是加總零數、可用和待命記憶體清單上的空間容量。可用記憶體隨時可供使用；零數記憶體是指填入零的記憶體頁數，以防後續程序讀取先前程序使用中的資料；待命記憶體是指從磁碟路徑上的某個程序的工作組 (其實體記憶體) 中移除的記憶體，但仍可恢復使用。此計數器僅顯示最後觀察到的值，而不是平均值。
