Currently, the only command that will output useful json for this kind 
of thing is 'ceph report'. I am finishing up on a patch to add json 
output capabilities to 'ceph health' and 'ceph status' though, but 
wasn't aiming at doing it with such level of detail -- basically, just 
output the same info as their plain counterparts, but using json instead.
