module: service_facts
short_description: Return service state information as fact data
description:
     - Return service state information as fact data for various service management utilities.
version_added: "2.5"
requirements: ["Any of the following supported init systems: systemd, sysv, upstart, openrc, AIX SRC"]
extends_documentation_fragment:
  -  action_common_attributes
  -  action_common_attributes.facts
attributes:
    check_mode:

    platform:
        platforms: posix
notes:
  - When accessing the C(ansible_facts.services) facts collected by this module,
    it is recommended to not use "dot notation" because services can have a C(-)
    character in their name which would result in invalid "dot notation", such as
    C(ansible_facts.services.zuul-gateway). It is instead recommended to
    using the string value of the service name as the key in order to obtain
    the fact data value like C(ansible_facts.services['zuul-gateway'])
  - AIX SRC was added in version 2.11.
