Overview
AOM supports alarm noise reduction. Alarms can be processed based on the alarm noise reduction rules to prevent notification storms.
Alarm noise reduction consists of four parts: grouping, deduplication, suppression, and silence.
AOM uses built-in deduplication rules. The service backend automatically deduplicates alarms. You do not need to manually create rules.

You need to manually create grouping, suppression, and silence rules. For details, see the following description.
Note
- This module is used only for message notification. All triggered alarms and events can be viewed on the Alarm List and Event List pages.
- All conditions of alarm noise reduction rules are obtained from metadata in alarm structs. You can use the default fields or customize your own fields.{"starts_at" : 1579420868000,"ends_at" : 1579420868000,"timeout" : 60000,"resource_group_id" : "5680587ab6*******755c543c1f","metadata" : {"event_name" : "test","event_severity" : "Major","event_type" : "alarm","resource_provider" : "ecs","resource_type" : "vm","resource_id" : "ecs123" ,"key1" : "value1" // Alarm tag configured when the alarm rule is created},"annotations" : {"alarm_probableCause_en_us": " Possible causes","alarm_fix_suggestion_en_us": "Handling suggestion"}}
