One of the timecheck-related patches on master introduced the 
possibility of outputting 'health' and 'status' in json.

'ceph status --format=json' however is only outputting the same info as 
its plain counterpart, but with a different entry for each map, sort of 
like this:

{
"monmap": "3 mons at 
{a=10.0.0.1:6789/0,b=10.0.0.2:6789/0,c=10.0.0.3:6789/0}",
"election_epoch": 2,
"quorum", "0 1 2",
...
}

This could be easily converted into something more useful though.
