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. author: Michael DeHaan ''' EXAMPLES = """ # Display facts from all hosts and store them indexed by I(hostname) at C(/tmp/facts). ansible all -m setup --tree /tmp/facts # Display only facts regarding memory found by ansible on all hosts and output them. ansible all -m setup -a 'filter=ansible_*_mb' # Display only facts returned by facter. ansible all -m setup -a 'filter=facter_*' # Display only facts returned by facter. ansible all -m setup -a 'filter=ansible_eth[0-2]' """ try: import selinux HAVE_SELINUX=True except ImportError: HAVE_SELINUX=False try: import json except ImportError: import simplejson as json class Facts(object): """ This class should only attempt to populate those facts that are mostly generic to all systems.
