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
