Amazon CloudWatch now supports Anomaly Detection on metrics shared across your accounts. CloudWatch Anomaly Detection now lets you track unexpected changes in metric behavior across multiple accounts from a single monitoring account through CloudWatch cross-account observability.

CloudWatch Anomaly Detection continuously tracks system or application metrics, determines a normal baseline, and automatically surfaces anomalies based off historical behavior. CloudWatch cross-account enables customers to share their metrics across multiple source accounts with a central monitoring account. With cross-account anomaly detection, service owners who deploy applications across multiple accounts can now track resource performance and alarm on anomalous behavior all from a single location within their unified monitoring account.

Anomaly Detection on cross-account metrics is available in all commercial AWS Regions.

To get started, log in to a monitoring account with CloudWatch Cross-Account observability configured, and navigate to your metric or alarm list. You can now choose to apply anomaly detection on a cross-account metric when you graph it or create an alarm on it. Standard anomaly detection alarming pricing applies to Anomaly Detection on cross-account metrics. Please refer to the CloudWatch Anomaly Detection documentation and pricing page for more details.
