As I just stumbled over it by accident: Ceph-Dash actually seems to provide exactly that: https://github.com/Crapworks/ceph-dash [CUT] REST Api If you access the address via commandline tools or programming languages, use content-type: application/json and you will get all the information as a json output (which is actually the json formatted output of ceph status --format=json. Anyways, this is not a wrapper around the ceph binary, it uses the python bindings of librados. This api can be requested by, for example, a nagios check, to check your overall cluster health. This brings the advantage of querying this information without running local checks on your monitor nodes, just by accessing a read only http api.
