Logging AWS User Experience Customization API calls using AWS CloudTrail

AWS User Experience Customization is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service. CloudTrail captures API calls for UXC as events, including management events and data events. The calls captured include calls from the UXC console and code calls to the UXC API operations. Using the information collected by CloudTrail, you can determine the request that was made to UXC, the IP address from which the request was made, when it was made, and additional details.

CloudTrail is active in your AWS account when you create the account and you automatically have access to the CloudTrail Event history. The CloudTrail Event history provides a viewable, searchable, downloadable, and immutable record of the past 90 days of recorded management events in an AWS Region. For more information, see Working with CloudTrail Event history in the AWS CloudTrail User Guide. There are no CloudTrail charges for viewing the Event history.

For an ongoing record of events in your AWS account past 90 days, create a trail or a CloudTrail Lake event data store.

UXC data events in CloudTrail

Data events provide information about the resource operations performed on or in a resource (for example, reading or writing to an Amazon S3 object). These are also known as data plane operations. Data events are often high-volume activities. By default, CloudTrail doesn’t log data events. The CloudTrail Event history doesn't record data events.

Additional charges apply for data events. For more information about CloudTrail pricing, see AWS CloudTrail Pricing.

You can log data events for the UXC resource types by using the CloudTrail console, AWS CLI, or CloudTrail API operations. For more information about how to log data events, see Logging data events with the AWS Management Console and Logging data events with the AWS Command Line Interface in the AWS CloudTrail User Guide.

The following table lists the UXC resource types for which you can log data events. The Resource type (console) column shows the value to choose from the Resource type list on the CloudTrail console. The resources.type value column shows the resources.type value, which you would specify when configuring advanced event selectors using the AWS CLI or CloudTrail APIs. The Data APIs logged to CloudTrail column shows the API calls logged to CloudTrail for the resource type.

You can configure advanced event selectors to filter on the eventName, readOnly, and resources.ARN fields to log only those events that are important to you. For more information about these fields, see AdvancedFieldSelector in the AWS CloudTrail API Reference.

UXC management events in CloudTrail

Management events provide information about management operations that are performed on resources in your AWS account. These are also known as control plane operations. By default, CloudTrail logs management events.

AWS User Experience Customization logs the following UXC control plane operations to CloudTrail as management events.

UXC event examples

An event represents a single request from any source and includes information about the requested API operation, the date and time of the operation, request parameters, and so on. CloudTrail log files aren't an ordered stack trace of the public API calls, so events don't appear in any specific order.

The following example shows a CloudTrail event that demonstrates the GetAccountCustomizations operation.
