Is it premature to start talking a little more about architecture so we can start splitting up the implementation work and focusing that energy differently? There is a lot of work we can do independently of the remaining decisions outlined in http://wiki.openstack.org/Meetings/MeteringAgenda.
Hi,

It looks like the architecture of metering is indeed always implemented in similar ways. I had discussions with a company yesterday about their own metering implementation (which will be used in production soon) and it also has an architecture matching what has been proposed so far in ceilometer. I added a few points to the architecture chapter in the wiki:

http://wiki.openstack.org/EfficientMetering#Architecture

including a note summarizing the conclusions of the discussion regarding need for an independent ceilometer agent in addition to the existing meters provided by the OpenStack components.

What do you think ?
