version_added: "2.1"
author: "Nathaniel Case (@qalthos)"
short_description: Collect facts from remote devices 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:
gather_subset:
description:
- When supplied, this argument will restrict the facts collected
to a given subset. Possible values for this argument include
all, hardware, config, and interfaces. Can specify a list of
values to include a larger subset. Values can also be used
with an initial C(M(!)) to specify that a specific subset should
not be collected.
