(已過時) 警示訂閱查詢效能監視

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

此監視會檢查警示訂閱資料來源模組的查詢效能。

Knowledge Base article:

摘要

此監視係追蹤選取符合訂閱準則的警示查詢效能。如果這些查詢的速度太慢，可能會造成通知子系統傳送的通知延遲。

原因

警示查詢速度變慢的原因通常是 SQL 資料庫中的查詢處理器超載。這可能是因為操作資料庫承受大量負載所致。如果警示查詢較複雜，也有可能減慢查詢的處理速度。

解決方式

通知子系統產生通知訊息時花費的時間過長。這是因為用來將訂閱中的警示準則與操作資料庫中的警示進行比對的查詢處理速度變慢。
