  5. In the Select Template step, select Upload a template to Amazon S3 and pick the template provided by Talend Cloud.

  7. In the Review step, select I acknowledge that AWS CloudFormation might create IAM resources.
  8. Click Create.
    The stack is created. If you select the stack, you can and find the RoleARN key value in the Outputs tab.
  9. Go back to Talend Cloud Management Console.

    Role ARN Amazon Resource Name uniquely identifying the target S3 bucket.
    External ID External ID of the target S3 bucket.
    Bucket Name Name of the target S3 bucket.
    Prefix (Optional) Prefix of the log files to be exported. In the target S3 bucket, the log files are created under a folder named after the prefix.
  11. Optional: Click Test export.
    A message indicates the timestamped log test file is exported to your bucket. Check that the file has correctly been exported before going further.

    In case of an error, review your AWS configuration or the parameters you have supplied on the Management Console export logs page.

  12. Click Save.


Log files will be exported to your S3 bucket any time you run a task, under the folder named after the prefix. Files are generated for each execution and named with the Execution ID.

Tasks run individually generate logs under [S3Bucket_name]/[prefix]/flows.

Tasks invoked through a plan generate logs under [S3Bucket_name]/[prefix]/ep.
Execution plans generate a log file that contains the end status of the execution (successful or failed).
