Logging with AWS CloudTrail for S3 Express One Zone
Amazon S3 is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service. CloudTrail captures all API calls for Amazon S3 as events. Using the information collected by CloudTrail, you can determine the request that was made to Amazon S3, the IP address from which the request was made, when it was made, and additional details. When a supported event activity occurs in Amazon S3, that activity is recorded in a CloudTrail event. You can use AWS CloudTrail trail to log management events and data events for S3 Express One Zone. For more information, see Amazon S3 CloudTrail events and What is AWS CloudTrail? in the AWS CloudTrail User Guide.
