Amazon CloudWatch Alarm Mute Rules eliminate alert fatigue

Posted on: Feb 25, 2026

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 to ensure critical issues that remain ongoing after the mute schedule window expires are not missed, alarm actions will be triggered for any alarms that did not returned to their original state when the mute schedule expired.

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 Amazon Web Services Regions supporting alarm-level muting, including Amazon Web Services China (Beijing) region, operated by Sinnet, and Amazon Web Services China (Ningxia) region, operated by NWCD.

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