CloudTrail log file entries for Amazon S3 and S3 on Outposts

A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source. It includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files are not an ordered stack trace of the public API calls, so they do not appear in any specific order.

For more information, see the following examples.

The following example shows a CloudTrail log entry that demonstrates the GET Service, PUT Bucket acl, and GET Bucket versioning actions.

Example: Amazon S3 on Outposts log file entries

Amazon S3 on Outposts management events are available via AWS CloudTrail. For more information, see Logging Amazon S3 API calls using AWS CloudTrail. In addition, you can optionally enable logging for data events in AWS CloudTrail.

A trail is a configuration that enables delivery of events as log files to an S3 bucket in a Region that you specify. CloudTrail logs for your Outposts buckets include a new field, edgeDeviceDetails, which identifies the Outpost where the specified bucket is located.

Additional log fields include the requested action, the date and time of the action, and the request parameters. CloudTrail log files are not an ordered stack trace of the public API calls, so they don't appear in any specific order.

The following example shows a CloudTrail log entry that demonstrates a PutObject action on s3-outposts.
