MySQL Server Aborted Connection Percent 監視器

Microsoft.MySQLServer.ManagedServer.Unix.AbortedConnectionPct.Monitor (UnitMonitor)

Knowledge Base article:

摘要

MySQL 伺服器目前的中止連線率。連線遭中止可能起因於用戶端應用程式的登入認證無效或發生逾時。此監視器會從狀態變數 'Aborted_connects' 擷取中止的連線數，再將其除以狀態變數 'Connections'。

原因

狀況不良狀態表示 MySQL 伺服器目前的中止連線率高。這可能是下列問題所致:

解決方法

若要解決中止連線數高的狀況，請選擇下列一或多個選項:

設定

預設設定

參數

預設值

警告閾值

大於 15

錯誤閾值

大於 30

樣本數

3

您可以使用上列定義的覆寫，變更所有執行個體或特定執行個體或群組的參數值。
