    callback: aws_resource_actions
    type: aggregate
    short_description: summarizes all "resource:actions" completed
    description:
      - Ansible callback plugin for collecting the AWS actions completed by all boto3 modules using
        AnsibleAWSModule in a playbook. Botocore endpoint logs need to be enabled for those modules, which can
        be done easily by setting debug_botocore_endpoint_logs to True for group/aws using module_defaults.
    requirements:
      - whitelisting in configuration - see examples section below for details.
'''

EXAMPLES = '''
example: >
  To enable, add this to your ansible.cfg file in the defaults block
    [defaults]
    callback_whitelist = aws_resource_actions
