Description RHOS Integration 2013-12-12 21:41:48 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/ceilometer/+spec/api-v2-improvement.

Description:

The API needs to evolve in order to solve more advanced questions from billing engines such as:

- Give me the maximum usage of a resource that lasted more than 1h
- Give me the use of a resource over a period of time, listing changes by increment of X volume over a period of Y time
- Provide additional statistical function (Deviation, Median, Variation, Distribution, Slope, etc...) which could be given as multiple results for a given data set collection
- OR operator in filter
