Report AWS Linked Account X Service

One way to do this is to use the AWS Organizations service, which allows you to centralize the management of multiple AWS accounts within a single master account. With AWS Organizations, you can use the AWS Cost and Usage Report (CUR) to get detailed data about your linked accounts and the services they are using.

To extract a report that contains information about linked accounts and services: Set up AWS Organizations in your master account. Set up the AWS Cost and Usage Report in your master account. Use the aws costandusagereport command-line interface (CLI) to create a report that includes data from your linked accounts. Use the aws costandusagereport list-reports command to get the names of the reports that are available for download. Use the aws costandusagereport get-report command to download the report in CSV format.

Alternatively, you can use the AWS Billing and Cost Management dashboard in the AWS Management Console to view data about your linked accounts and the services they are using.
