Metrics include aggregated transaction statistics and capacity data about requests to a storage service. Transactions are reported at both the API operation level as well as at the storage service level, and capacity is reported at the storage service level. Metrics data can be used to analyze storage service usage, diagnose issues with requests made against the storage service, and to improve the performance of applications that use a service.
