module: setup
version_added: historical
short_description: Gathers facts about remote hosts
options:
gather_subset:
version_added: "2.1"
description:
- "if supplied, restrict the additional facts collected to the given subset.
Possible values: all, hardware, network, virtual, ohai, and
facter Can specify a list of values to specify a larger subset.
Values can also be used with an initial C(!) to specify that
that specific subset should not be collected. For instance:
!hardware, !network, !virtual, !ohai, !facter. Note that a few
facts are always collected. Use the filter parameter if you do
not want to display those."
required: false
default: 'all'
gather_timeout:
version_added: "2.2"
description:
- "Set the default timeout in seconds for individual fact gathering"
required: false
default: 10
filter:
version_added: "1.1"
description:
- if supplied, only return facts that match this shell-style (fnmatch) wildcard.
required: false
default: '*'
fact_path:
version_added: "1.3"
description:
- path used for local ansible facts (*.fact) - files in this dir
will be run (if executable) and their results be added to ansible_local facts
if a file is not executable it is read. Check notes for Windows options. (from 2.1 on)
File/results format can be json or ini-format
required: false
default: '/etc/ansible/facts.d'
description:
- This module is automatically called by playbooks to gather useful
variables about remote hosts that can be used in playbooks. It can also be
executed directly by C(/usr/bin/ansible) to check what variables are
available to a host. Ansible provides many I(facts) about the system,
automatically.
notes:
- More ansible facts will be added with successive releases. If I(facter) or
I(ohai) are installed, variables from these programs will also be snapshotted
into the JSON file for usage in templating. These variables are prefixed
with C(facter_) and C(ohai_) so it's easy to tell their source. All variables are
bubbled up to the caller. Using the ansible facts and choosing to not
install I(facter) and I(ohai) means you can avoid Ruby-dependencies on your
remote systems. (See also M(facter) and M(ohai).)
- The filter option filters only the first level subkey below ansible_facts.
- If the target host is Windows, you will not currently have the ability to use
C(filter) as this is provided by a simpler implementation of the module.
- If the target host is Windows you can now use C(fact_path). Make sure that this path
exists on the target host. Files in this path MUST be PowerShell scripts (``*.ps1``) and
their output must be formattable in JSON (Ansible will take care of this). Test the
output of your scripts.
This option was added in Ansible 2.1.
