CloudWatch adds managed Prometheus collectors

CloudWatch now provides fully managed collectors for Prometheus metrics, eliminating the need for users to deploy and manage agents. This supports monitoring for EKS, EC2, ECS, MSK, and OpenSearch Service workloads.

Metrics collected via managed Prometheus collectors are delivered in OpenTelemetry format and can be queried alongside AWS vended metrics using PromQL. This enables unified alarming, dashboarding, and cross-service correlation within CloudWatch.

Managed collectors support various service discovery mechanisms, including Kubernetes service discovery for EKS, AWS Cloud Map for ECS, direct instance scraping for EC2, and open monitoring endpoints for MSK and OpenSearch.

Previously, users had to manage their own OpenTelemetry Collectors for Prometheus metrics. Managed collectors automate provisioning, scaling, and collection, reducing operational overhead. Users only need to provide a scrape configuration and resource connection.

This feature is available in all AWS regions with the CloudWatch OTLP endpoint, excluding Asia Pacific (New Zealand). Pricing is based on hourly charges for the managed collectors and standard CloudWatch OpenTelemetry metric ingestion rates.
