+++ This bug was initially created as a clone of Bug #1115994 +++ Components that currently use the RPC/messaging facility forked from Nova need to transition to using the common oslo.messaging facility.
This has landed upstream since juno-1: https://blueprints.launchpad.net/ceilometer/+spec/switch-to-oslo.messaging However it will not be backportable to stable/icehouse and therefore cannot be considered for the rhos5. Bumping to the juno-derived rhos6 instead.
This is landed upstream since juno-1, and released in RHOS6.
