Amazon CloudWatch Alarms now supports tags in alarm actions payload

News



Amazon CloudWatch announces support for including alarm tags in action payloads and EventBridge events, enabling customers to route and filter alarm notifications by tag without additional lookups.

  • Alarm tags are added to messages sent to SNS, Lambda, and EventBridge when alarm state changes
  • Eliminates need for ListTagsForResource API calls to correlate tag metadata with alarm events
  • Configurable per alarm with options to include all tags, selected keys, or exclude specific keys
  • Supported for metric, composite, and log alarms
  • Available in all AWS Regions except Middle East (UAE) and Middle East (Bahrain)

This feature streamlines notification routing for teams managing many alarms through shared pipelines by delivering tag information directly in messages.
