Amazon Managed Service for Prometheus now supports 200M active metrics per workspace. Amazon Managed Service for Prometheus is a fully managed Prometheus-compatible monitoring service that makes it easy to monitor and alarm on operational metrics at scale. Prometheus is a Cloud Native Computing Foundation open source project for monitoring and alerting that is optimized for container environments such as Amazon EKS and Amazon ECS. With this release, customers can send up to 200M active metrics to a single workspace after filing a limit increase, and can create many workspaces per account, enabling the storage and analysis of billions of Prometheus metrics. To get started, customers can create an Amazon Managed Service for Prometheus workspace and increase their workspace active series limits by filing a limit increase in AWS Support Center or AWS Service Quotas.
