Monitoring Metrics Object

In Ceilometer, the meters are polled in the form of Counter(namedtuple), do we need two different peer objects or a common lower level object for both meters and metrics?

After the Havana design summit, it's agreed that a common schema will be shared between meters and metrics. So The target of this blueprint is to check and confirm that the customized metrics(openstack-related) will work with the UDP publisher and the common schema. e.g. metrics produced by openstack logging tools, Ganglia, Statsd etc. Bridge the gaps if there is any.
