MSSQL 2008: 收集数据库引擎平均等待时间(ms)

Microsoft.SQLServer.2008.DBEngine.AverageWaitTime.Collection (Rule)

SQL 2008 数据库引擎平均等待时间性能收集规则

摘要

针对 SQL 2008 数据库引擎的平均等待时间(ms)

导致等待的每个锁请求的平均等待时间(毫秒)。此计数器基于数据库引擎计数器，并且对于一个 SQL 实例上的所有数据库具有完全相同的值。

这是用于获取锁的平均等待时间，以毫秒为单位。该值越低，性能越好。如果该值变得超过 500，则可能正在出现阻塞情况，并且您最好找到阻塞的原因并予以修复。
