MySQL Server 中止的连接百分比监视器

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

Knowledge Base article:

摘要

正在中止的 MySQL Server 连接的百分比。客户端应用程序的登录凭据无效或登录超时可能导致连接中止。此监视器从状态变量“Aborted_connects”获取中止的连接数量，然后除以状态变量“Connections”。

原因

运行不正常状态表示 MySQL Server 上中止的连接的百分比高。这可能是由以下问题引起的：

解决方案

要解决连接频繁中止的问题，请选择以下一个或多个选项：

配置

默认配置

参数

默认值

警告阈值

大于 15

错误阈值

大于 30

样本数

3

替代可用于更改以上为所有实例或为特定实例或组定义的参数值。
