Setting Up CloudWatch Alarm Notifications

Overview

Domain expertise for configuring Amazon CloudWatch alarm notification channels using Amazon SNS topics and subscriptions. Covers creating encrypted SNS topics, setting up subscriptions for email, SMS, and webhook endpoints, configuring topic policies for CloudWatch access, and linking alarms to notification actions.

Set up alarm notifications

To configure notification channels for a CloudWatch alarm, follow the procedure exactly. See CloudWatch alarm notification setup procedure.

Troubleshooting

Email notifications not received

Verify the email subscription was confirmed. Use aws sns list-subscriptions-by-topic to check that the subscription status is "Confirmed" rather than "PendingConfirmation".

SMS notifications failing

Ensure the phone number is in E.164 format (e.g., +12345678901) and that SMS is supported in your AWS region.

Alarm not triggering notifications

Verify the alarm has the correct SNS topic ARN in its AlarmActions using aws cloudwatch describe-alarms, and ensure ActionsEnabled is set to true.
