You can use Amazon CloudWatch Events to detect and react to changes in the status of AWS Personal Health Dashboard (AWS Health) events.

Depending on the type of event, you can send notifications, capture event information, take corrective action, initiate events, or take other actions. You can select the following types of targets when using CloudWatch Events as a part of your AWS Health workflow:
AWS Lambda functions
Kinesis streams
Amazon SQS queues
Built-in targets (CloudWatch alarm actions)
Amazon SNS topics
