AOM Alarm Noise Reduction Overview
AOM supports alarm noise reduction. Alarms can be processed based on the alarm noise reduction rules to prevent notification storms.
Description
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 Creating an AOM Alarm Grouping Rule, Creating an AOM Alarm Suppression Rule, and Creating an AOM Alarm Silence Rule.
Constraints
- This module is used only for message notification. All triggered alarms and events can be viewed on the alarm list page.
- 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.
