Amazon usage metrics

CloudWatch collects metrics that track the usage of some Amazon resources and APIs. These metrics are published in the AWS/Usage namespace. Usage metrics in CloudWatch allow you to proactively manage usage by visualizing metrics in the CloudWatch console, creating custom dashboards, detecting changes in activity with CloudWatch anomaly detection, and configuring alarms that alert you when usage approaches a threshold.

Some Amazon services integrate these usage metrics with Service Quotas. For these services, you can use CloudWatch to manage your account's use of your service quotas. For more information, see Visualizing your service quotas and setting alarms.
