  title: AWS CloudWatch Amazon CloudWatch Alarms Anomaly Detection API
  description: Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real time. You can use CloudWatch to collect and track metrics, which are variables you can measure for your resources and applications. CloudWatch alarms watch metrics and automatically send notifications or make changes to the resources you are monitoring when a threshold is breached. CloudWatch dashboards provide a unified view of your AWS resources, custom applications, and services.

      description: Creates an anomaly detection model for a CloudWatch metric. You can use the model to display a band of expected normal values when the metric is graphed. If you have enabled unified cross-account observability, and this account is a monitoring account, the metric can be in the same account or a source account.
