module: dnos9_facts
version_added: "2.2"
author: "Dhivya P (@dhivyap)"
short_description: Collect facts from remote devices running Dell OS9
description:
- Collects a base set of device facts from a remote device that
is running Dell OS9. This module prepends all of the
base network fact keys with C(ansible_net_<fact>). The facts
module will always collect a base set of facts from the device
and can enable or disable collection of additional facts.
extends_documentation_fragment: dnos9
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 M(!) to specify that a specific subset should
not be collected.
