Amazon Route 53 launches capacity utilization metric for Resolver endpoints

Starting today, you can enable Amazon CloudWatch metric (ResolverEndpointCapacityStatus) to monitor the status of the query capacity for Elastic Network Interfaces (ENIs) associated with your Route 53 Resolver endpoint in Amazon Virtual Private Cloud (VPC). The new metric enables you to quickly view whether the Resolver endpoint is at the risk of meeting the service limit for query capacity, and take remediation steps like instantiating additional ENIs to meet the capacity needs.

Before today, you could enable CloudWatch to monitor the number of DNS queries that were forwarded by Route 53 Resolver endpoints, over a default five-minute interval, and make further estimations on when your endpoints will meet the query limits. With this launch, you can now enable the new metric to get direct alerts on the current status of your Resolver endpoint capacity, without requiring you to make additional estimations for calculating capacity of each endpoint. The status is reported for each Resolver endpoint, indicating whether the endpoint is operating within the normal capacity limit (0 – OK), has at least one ENI exceeding 50% capacity utilization (1 – Warning), or has at least one ENI exceeding 75% capacity utilization (2 – Critical). The new metric simplifies capacity management for Route 53 Resolver endpoints by providing clear, actionable signals for scaling decisions, without requiring additional analysis on the query volume.

To learn more about the launch, read the documentation or visit the Route 53 Resolver page. There is no charge for the metric, although you will incur charges for usage of Resolver endpoints.
