(已弃用)警报订阅查询性能监视器

Microsoft.SystemCenter.HealthServiceModules.AlertSubscriptionDataSourceModule.QueryPerformanceMonitor (UnitMonitor)

此监视器检查警报订阅数据源模块的查询性能。

Knowledge Base article:

摘要

此监视器跟踪下列查询的性能：用来选择匹配订阅条件的警报。如果这些查询太慢，则可能导致通知子系统发送通知延迟。

原因

SQL 数据库中的查询处理器超载通常会减缓警报查询的速度。操作数据库可能超负荷。如果警报查询过于复杂，则会减缓处理查询的速度。

解决方法

通知子系统需要很长时间生成通知消息。这是由于查询处理的减缓造成的，该查询处理用于根据操作数据库中的警报来匹配订阅中显示的警报条件。
