with a small description of each command, is provided when the requested
path is incomplete/partially matching. Requesting / will redirect to
the value of **restapi base url**, and that path will give a full list
-of all known commands. The command set is very similar to the commands
+of all known commands.
+For example, requesting ``api/vX.X/mon`` will return the list of API calls for
+monitors - ``api/vX.X/osd`` will return the list of API calls for OSD and so on.

supported by the **ceph** tool. One notable exception is that the
``ceph pg <pgid> <command>`` style of commands is supported here
as ``tell/<pgid>/command?args``.
