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.

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.
