Starting today, you can use AWS Budgets to monitor how much of your Amazon EC2, Amazon RDS, Amazon Redshift, and Amazon ElastiCache instance usage is covered by reservations, and receive alerts when your coverage falls below the threshold you define.

Reserved Instance (RI) coverage tracks the number of running instance hours that are covered by RIs, and can be measured over a daily, monthly, quarterly or yearly cadence. For example, you can monitor your RI coverage either at an aggregate level (e.g., monthly coverage of your entire Amazon EC2 RI fleet) or at a more granular level of detail (e.g., monthly coverage of Amazon RDS db.r3.large instances running in US East region). You can then define up to five notifications per budget. Each notification can be sent to ten email subscribers and broadcast to an Amazon SNS topic of your choice.

To learn more about setting RI Coverage alerts, please refer to the AWS Budgets webpage or the Managing your Costs with Budgets user guide. You can also proceed directly to the AWS Budgets dashboard.
