AWS CloudWatch Alarm Mute Rules eliminate alert fatigue

Amazon CloudWatch now supports Alarm Mute Rules, enabling customers to temporarily mute alarm notifications during planned deployments, maintenance windows, and off-hours without compromising monitoring visibility. This new capability helps eliminate alert fatigue while maintaining complete situational awareness across their infrastructure.

Alarm Mute Rules transform operational workflows by allowing teams to create one-time or recurring rules that silence notifications for up to 100 individual alarms around deployment calendars, scheduled maintenance activities, or predictable off-hours periods when non-critical alerts become disruptive. Customers can configure actions for OK, ALARM, and INSUFFICIENT_DATA states, and when mute rules expire, any previously muted actions are automatically triggered as long as the alarm remains in the same state it was in when the actions were muted, ensuring critical issues are never overlooked while preventing unnecessary alert fatigue.

This eliminates the operational risk of forgotten script-based workarounds and reduces alert noise during planned activities, enabling engineering teams to focus on core business initiatives rather than managing notification fatigue.

CloudWatch Alarm Mute Rules is available today in all AWS Regions supporting alarm-level muting.

To get started, see CloudWatch User Guide for Alarm Mute Rules. You can create mute rules through the Amazon CloudWatch Console.
