# Amazon API usage metrics
<a name="AWS-API-Usage-Metrics"></a>

Most APIs that support Amazon CloudTrail logging also report usage metrics to CloudWatch. API usage metrics in CloudWatch allow you to proactively manage API usage by visualizing metrics in the CloudWatch console, creating custom dashboards, detecting changes in activity with CloudWatch anomaly detection, and configuring alarms that alert when usage approaches a threshold.

 You can use the he following table to learn about services that report API usage metrics to CloudWatch. The table lists the values to use for the `Service` dimension, so you can see the usage metrics from that service. You can use the procedure in this section to view the list of a service's APIs that report usage metrics to CloudWatch.
