AWS Marketplace customers can now view AWS CloudTrail logs to monitor procurement activity for their AWS Marketplace subscriptions (agreements). Customers can view activity logs anytime a user in the AWS Account subscribes or unsubscribes to an AWS Marketplace SaaS, AMI, container, or professional services product. This visibility will provide improved security & governance to account administrators or procurement/finance users. Logs include:
[Subscribe] Creation of any new agreement (by accepting an offer)
[Subscribe] Amendment of an existing agreement (such as increasing units of a dimension/instance type, or changing auto-renewal status)
[Subscribe] Replacement of an existing agreement by another agreement (by accepting an ‘Agreement Based Offer’)
[Unsubscribe] Cancellation of an existing agreement from the Marketplace Console
