module: routeros_facts
author: "Egor Zaitsev (@heuels)"
short_description: Collect facts from remote devices running MikroTik RouterOS
description:
- Collects a base set of device facts from a remote device that
is running RotuerOS. 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.
options:
gather_subset:
description:
- When supplied, this argument will restrict the facts collected
to a given subset. Possible values for this argument include
C(all), C(hardware), C(config), and C(interfaces). Can specify a list of
values to include a larger subset. Values can also be used
with an initial C(!) to specify that a specific subset should
not be collected.
required: false
default: '!config'
