Currently 'ceph -s' or 'ceph health' will give you the best available information, but this is a aspect that is being worked on. Getting more and better monitoring is on the wishlist (so I heard). There is a issue about this in the tracker: http://tracker.newdream.net/issues/685 Once this information is exposed via libceph, writing an application which shows it in a nice format is trivial.
