Prerequisites​

This guide assumes that you have already installed and configured Fix Inventory to collect your AWS resources.

Directions​

  1. Execute the following search command in Fix Inventory Shell:

    > search is(aws_cloud_trail) and trail_status.is_logging==true and trail_status.latest_delivery_attempt_succeeded < -1d
    ​kind=aws_cloud_trail, ..., region=fixinventory-poweruser
    ​kind=aws_cloud_trail, ..., account=poweruser-team

  2. Pipe the search command into the dump command:

    > search is(aws_cloud_trail) and trail_status.is_logging==true and trail_status.latest_delivery_attempt_succeeded < -1d | dump
    ​reported:
    ​  id: /aws/cloudtrail/123
    ​  name: some-name
    ​  ctime: '2022-12-05T22:53:14Z'
    ​  kind: aws_cloud_trail
