module: ceph_facts
short_description: Runs the I(ceph) monitoring programs on the remote system
description:
- Runs the I(ceph) program to discover the filesystem status
returning JSON data that can be useful for inventory purposes.
version_added: "1.1"
options:
filter:
description:
- if supplied, only return facts that match this shell-style (fnmatch) wildcard.
required: false
default: '*'
examples:
- code: ansible monitor-ceph01.cluster -m ceph_facts
description: "Get all the possible known information from ceph cluster"
- code: ansible monitor-ceph01.cluster -m ceph_facts -a 'filter=quorum*'
description: "Get all the information related to quorum status"
notes:
- The facts are not very structured right now and requires more work.
requirements: [ "ceph" ]
