Incorrect costing for data-pipeline

Hello.

Why not try searching using the Tag editor?

If you can't find anything, I recommend opening a case with AWS Support under "Account and billing".
Inquiries under "Account and billing" can be made free of charge.

1. Double check for existing pipelines aws datapipeline list-pipelines --region us-east-1

2. Check if there are any CloudFormation stacks that might have created Data Pipeline resources: aws cloudformation list-stacks --region us-east-1 --stack-status-filter CREATE_COMPLETE

3. Review IAM roles: Check if any roles with Data Pipeline permissions have been used recently.

4. Check CloudTrail Logs: Use AWS CloudTrail to review logs of API calls in the us-east-1 region. Look for any datapipeline related calls: aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=CreatePipeline --region us-east-1

5. Use the AWS Cost Explorer and detailed billing reports to drill down into the costs associated with Data Pipeline:

   AWS Cost Explorer: Filter costs by service (Data Pipeline) and region (us-east-1) to get a detailed view of what is incurring costs.

   Detailed Billing Report: If Cost Explorer does not provide sufficient detail, you can generate and download the Detailed Billing Report (DBR) from the AWS Billing Console.
