Synopsis
--------


* Retrieve facts from a Junos device using the `PyEZ fact gathering system <http://junos-pyez.readthedocs.io/en/stable/jnpr.junos.facts.html>`_.
* Also returns the committed configuration of the Junos device if the *config_format* option has a value other than ``none``.



Requirements
------------
The following software packages must be installed on hosts that execute this module:

* `junos-eznc <https://github.com/Juniper/py-junos-eznc>`_ >= 2.5.2
* Python >= 3.5
