description:
- This module prints statements during execution and can be useful
for debugging variables or expressions without necessarily halting
the playbook. Useful for debugging together with the only_if directive.

- The customized message that is printed. If ommited, prints a generic
message.

default: "Hello world!"
rc:
description:
- The return code of the module. If fail=yes, this will default to 1.
required: false
default: 0
fail:
description:
- A boolean that indicates whether the debug module should fail or not.
required: false
default: "no"
examples:
- code:
- local_action: debug msg="System $inventory_hostname has uuid $ansible_product_uuid"
- local_action: debug msg="System $inventory_hostname lacks a gateway" fail=yes
only_if: "is_unset('${ansible_default_ipv4.gateway}')"
- local_action: debug msg="System $inventory_hostname has gateway ${ansible_default_ipv4.gateway}"
only_if: "is_set('${ansible_default_ipv4.gateway}')"
