Event History
Event history in AWS CloudTrail is a searchable record of the last 90 days of API activity within your AWS account. It provides insights into the management activities performed by users, roles, or services. You can access the event history from the AWS Management Console, AWS CLI, or the CloudTrail API. This data helps you monitor the API activity and changes made to resources in your account. For example, by analyzing the event history, you can detect unusual behavior, troubleshoot resource changes, and identify security issues.
