How to manage alert notifications-Simple Log Service(SLS)-阿里云帮助中心

A notification policy controls how SLS delivers alerts — who gets notified, through which channels, and under what conditions.

When an alert is triggered, the notification policy manages the full delivery pipeline: it silences redundant alerts, deduplicates repeated incidents, merges related events, and dispatches the result to the appropriate notification channels — reaching specific users, user groups, or on-call groups.

A notification policy consists of four components:

Component	Role
Alert policy	Defines the conditions for triggering, silencing, deduplicating, and merging alerts
Action policy	Matches incidents to notification channels and recipients based on alert attributes
Content template	Controls the format and content of notification messages
Global default calendar	Sets the baseline schedule for when notifications are sent
