The problem with that approach, IIUC, is that the statsd metrics
provide insufficient context.

Ceilometer wants to meter usage on a per-user & per-tenant basis,
so captures[1] the http-x-user-id and http-x-tenant-id headers from
the incoming request for this purpose.

Similarly, the resource-id is fabricated from the swift account.

I don't think this supporting contextual info would be available
from raw statsd metrics, or?
