可用性複本連接監視器

Microsoft.SQLServer.2012.AlwaysOn.AllAvailabilityReplicasAreConnected (UnitMonitor)

可用性複本連接

Knowledge Base article:

摘要

此監視器會積存所有可用性複本的連接狀態，並檢查是否有任何可用性複本為 DISCONENCTED。當任何可用性複本為 DISCONNECTED 時，監視器就會處於狀況不良的狀態。否則，監視器就會處於狀況良好的狀態。

原因

在此可用性群組中，至少一個次要複本未連接至主要複本。連接狀態為 DISCONNECTED。

解決方式

使用可用性複本監視器狀態，尋找處於 DISCONNECTED 狀態的可用性複本，然後解決可用性複本的問題。
