NAME

       ceph-conf - ceph conf file tool

SYNOPSIS

       ceph-conf -c conffile --list-all-sections
       ceph-conf -c conffile -L
       ceph-conf -c conffile -l prefix
       ceph-conf key -s section1 ...
       ceph-conf [-s section ] [-r] --lookup key
       ceph-conf [-s section ] key

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:

       -L, --list-all-sections
              list all sections in the configuration file.

       -l, --list-sections *prefix*
              list  the  sections  with  the given prefix. For example, --list-sections mon would
              list all sections beginning with mon.

       --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.

       -h, --help
              print a summary of usage.

OPTIONS

       -c *conffile*
              the Ceph configuration file.

       --filter-key *key*
              filter section list to only include sections with given key defined.

       --filter-key-value *key* ``=`` *value*
              filter section list to only include sections with given key/value pair.

       --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]

       --pid *pid*
              override the $pid when expanding options. For example, if an option  is  configured
              like  /var/log/$name.$pid.log,  the  $pid  portion in its value will be substituted
              using the PID of ceph-conf instead of the PID of the process  specified  using  the
              --name option.

       -r, --resolve-search
              search  for  the  first  file  that  exists and can be opened in the resulted comma
              delimited search list.

       -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.
