SQL

This control uses a named query:

select
  address as resource,
  case
    when jsonb_typeof(attributes_std -> 'network_interface') is null then 'skip'
    when (jsonb_typeof(attributes_std -> 'network_interface'))::text = 'object' then 'ok'
    else 'alarm'
  end status,
  split_part(address, '.', 2) || case
    when jsonb_typeof(attributes_std -> 'network_interface') is null then ' has no ENI attached'
    when (jsonb_typeof(attributes_std -> 'network_interface'))::text = 'object' then ' has 1 ENI attached'
    else ' has ' || (jsonb_array_length(attributes_std -> 'network_interface')) || ' ENI(s) attached'
  end || '.' as reason
  
  , path || ':' || start_line
from
  terraform_resource
where
  type = 'aws_instance';
