After configuring alert notifications using the observability service of version 1.4.0 or later, you can also configure the following two alert notification policies for the alert object.
Silence policy
Once enabled, alert notifications related to the silent object will no longer be delivered via email, SNMP traps, or webhook channels before the end time set by users.
Aggregation policy
Once enabled, within the period set by users, the alert entries triggered by the same alert object and the same alert rule will be aggregated into one alert notification, which is then delivered via email, SNMP trap, or webhook channel.
