The issue here is that the default support in ceilometer will assume that object-storage is swift, rather than a ceph-radosgw which behaves in a slightly different way in terms of URI's.
This is a missing feature in the ceilometer charm, probably best resolved using a relation between ceph-radosgw and ceilometer to allow discovery and configuration of the polling agent in ceilometer, and enablement of the required account and stats in radosgw.
