+
+Description
+===========
+
+**ceph-conf** is a utility for getting information from a ceph
+configuration file. As with most Ceph programs, you can specify which
+Ceph configuration file to use with the ``-c`` flag.
+
+Note that unlike other ceph tools, **ceph-conf** will *only* read from
+config files (or return compiled-in default values)--it will *not*
+fetch config values from the monitor cluster.  For this reason it is
+recommended that **ceph-conf** only be used in legacy environments
+that are strictly config-file based.  New deployments and tools should
+instead rely on either querying the monitor explicitly for
+configuration (e.g., ``ceph config get <daemon> <option>``) or use
+daemons themselves to fetch effective config options (e.g.,
+``ceph-osd -i 123 --show-config-value osd_data``).  The latter option
+has the advantages of drawing from compiled-in defaults (which
+occasionally vary between daemons), config files, and the monitor's
+config database, providing the exact value that that daemon would be
+using if it were started.
+
+Actions
+=======
+
+**ceph-conf** performs one of the following actions:
+
+.. option:: -L, --list-all-sections
+
+   list all sections in the configuration file.
+
+.. option:: -l, --list-sections *prefix*
+
+   list the sections with the given *prefix*. For example, ``--list-sections mon``
+   would list all sections beginning with ``mon``.
+
+.. option:: --lookup *key*
+
+   search and print the specified configuration setting. Note:  ``--lookup`` is
+   the default action. If no other actions are given on the command line, we will
+   default to doing a lookup.
+
+.. option:: -h, --help
+
+   print a summary of usage.
+
+
+Options
+=======
+
+.. option:: -c *conffile*
+
+   the Ceph configuration file.
+
+.. option:: --filter-key *key*
+
+   filter section list to only include sections with given *key* defined.
+
+.. option:: --filter-key-value *key* ``=`` *value*
+
+   filter section list to only include sections with given *key*/*value* pair.
+
+.. option:: --name *type.id*
+
+   the Ceph name in which the sections are searched (default 'client.admin').
+   For example, if we specify ``--name osd.0``, the following sections will be
+   searched: [osd.0], [osd], [global]
+
+.. option:: -r, --resolve-search
+
+   search for the first file that exists and can be opened in the resulted
+   comma delimited search list.
+
+.. option:: -s, --section
+
+   additional sections to search.  These additional sections will be searched
+   before the sections that would normally be searched. As always, the first
+   matching entry we find will be returned.
+
+
+Examples
+========
+
+To find out what value osd 0 will use for the "osd data" option::
+
+        ceph-conf -c foo.conf  --name osd.0 --lookup "osd data"
+
+To find out what value will mds a use for the "log file" option::
+
+        ceph-conf -c foo.conf  --name mds.a "log file"
+
+To list all sections that begin with "osd"::
+
+        ceph-conf -c foo.conf -l osd
+
+To list all sections::
+
+        ceph-conf -c foo.conf -L
+
+To print the path of the "keyring" used by "client.0"::
+
+       ceph-conf --name client.0 -r -l keyring
+
+
+Files
+=====
+
+``/etc/ceph/$cluster.conf``, ``~/.ceph/$cluster.conf``, ``$cluster.conf``
+
+the Ceph configuration files to use if not specified.

+
+Availability
+============
