AWS Config is an Amazing way to track to the changes and relationship among the various AWS Services. It provides little bit of perspective of CDC – Change Data Capture functionality across the AWS Services used under the account.
Recently when I tried to look for changes in one of the AWS Config’s Cousin [ CloudTrail ] to see the information about when CloudTrail logging was initiated etc. The Lookup by Resource ID accepts the CloudTrail Trail’s Name -[What is CloudTrail Trail’s Name ? ] I tried all possible combinations of CloudTrail, S3Bucket Name, empty; but none of them succeeded.
Turned out it is Default [ D in Upper Case ]; I got this information after contacting the AWS via. AWS Forums.
Hope this helps.
