Logging and Monitoring in Amazon Service Catalog
Amazon Service Catalog integrates with Amazon CloudTrail, a service that captures all of the Amazon Service Catalog API calls and
delivers the log files to an Amazon S3 bucket that you
specify.
For more information, see Logging Amazon Service Catalog API
Calls with CloudTrail.
You can also use notification constraints to set up Amazon SNS notifications about stack events. For more information, see Amazon Service Catalog Notification Constraints.
