Setting Up Notifications and Events for Systems Manager Parameters

You can use Amazon CloudWatch Events and Amazon SNS to notify you about changes to Systems Manager Parameters. You can be notified when a parameter is created, updated, or deleted.

You can also use CloudWatch to perform an action on a target for specific parameter events. This means, for example, that you can execute an AWS Lambda function to recreate a parameter when it is deleted. You can also set up a notification to trigger a Lambda function when your database password is updated. The Lambda function can force your database connections to reset or reconnect with the new password.

Before You Begin

Create an Amazon SNS topic. For more information, see Getting Started with Amazon SNS in the Amazon Simple Notification Service Developer Guide.
