Following up on multiple discussions with Angus, Julien, Doug and other, it seems that we need a way to compute values from aggregate counters from the API. I think we can achieve this with very few changes on the storage schema, and a few more on the API, so I have written a proposal in the form of a blueprint which I like you to examine and comment... https://blueprints.launchpad.net/ceilometer/+spec/multi-dimensions Do not forget to look under the "Read the full spec" link. I also added another proposal to add an average function: https://blueprints.launchpad.net/ceilometer/+spec/api-aggregate-average Thanks for your feedback.
