Amazon CloudWatch now supports cross-account metrics centralization
Amazon CloudWatch provides cross-account and cross-region metrics centralization, allowing automatic replication of metrics to a single destination account for unified monitoring and management.
Amazon CloudWatch Metrics Centralization is now generally available. This feature allows you to define centralization rules through AWS Organizations to automatically replicate metrics from source accounts and regions into a centralized destination account. Central teams gain full ownership of the data for querying, alarming, compliance, and governance. The centralized metrics work with both CloudWatch and OpenTelemetry metrics, and are fully compatible with Metrics Insights, dashboards, alarms, Metric Math, anomaly detection, Metric Streams, and PromQL.
