Attributes: version (dict): version information of the Ceph cluster. data (dict): a dictionary of the parsed output. The ``data`` attribute is a dictionary containing the parsed output of the ``ceph insights`` command. The following are available in ``data``: * ``crashes`` - summary of daemon crashes for the past 24 hours * ``health`` - the current and historical (past 24 hours) health checks * ``config`` - cluster and daemon configuration settings * ``osd_dump`` - osd and pool information * ``df`` - storage usage statistics * ``osd_tree`` - osd topology * ``fs_map`` - file system map * ``crush_map`` - the CRUSH map * ``mon_map`` - monitor map * ``service_map`` - service map * ``manager_map`` - manager map * ``mon_status`` - monitor status * ``pg_summary`` - placement group summary * ``osd_metadata`` - per-OSD metadata * ``version`` - ceph software version * ``errors`` - any errors encountered collecting this data The ``version`` attribute contains a normalized view of ``["version"]``.
