摘要

Windows 上 SQL DBEngine 的平均等待时间(毫秒)

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，并且最好找到阻塞的原因并予以修复。

可替代参数

名称	说明	默认值
已启用	启用或禁用工作流。	是
间隔(秒)	运行工作流的重复间隔时间(秒)。	900
超时(秒)	指定工作流在关闭之前允许运行的时间，并标记为失败。	300
数据库连接超时(秒)	如果在指定期间无法访问数据库，工作流将失败并注册一个事件。	15
