module: junos_facts
version_added: "2.1"
author: "Peter Sprygada (@privateip)"
short_description: Collect facts from remote device running Junos
description:
  - Collects fact information from a remote device running the Junos
    operating system.  By default, the module will collect basic fact
    information from the device to be included with the hostvars.
    Additional fact information can be collected based on the
    configured set of arguments.
extends_documentation_fragment: junos
options:
  config:
    description:
      - The C(config) argument instructs the fact module to collect
        the configuration from the remote device.  The configuration
        is then included in return facts.  By default, the configuration
        is returned as text.  The C(config_format) can be used to return
        different Junos configuration formats.
    required: false
    default: null
  config_format:
    description:
      - The C(config_format) argument is used to specify the desired
        format of the configuration file.  Devices support three
        configuration file formats.  By default, the configuration
        from the device is returned as text.  The other option xml.
        If the xml option is chosen, the configuration file is 
        returned as both xml and json.
    required: false
    default: text
    choices: ['xml', 'text']
requirements:
  - junos-eznc
notes:
  - This module requires the netconf system service be enabled on
    the remote device being managed
