Amazon ECR now supports additional metrics for monitoring repositories

Posted on: Feb 6, 2026

Amazon Elastic Container Registry (ECR) now enables customers to monitor additional repository metrics through Amazon CloudWatch. These new metrics, RepositoryCount and ImagesPerRepositoryCount, help customers identify growth trends of images by repository as well as understand their trends for creating and deleting repositories. With these insights, customers can easily identify anomalous behavior and alert themselves when their usage approaches the service quota.

These metrics are available in all AWS commercial and AWS GovCloud (US) Regions at no additional cost. To learn more about Amazon ECR repository metrics, please review our documentation.
