OpenStack Summit April 2013

This session will include the following subject(s):

API improvements for Ceilometer:

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 a GROUP BY function
- Provide additional statistical function (Deviation, Median, Variation, Distribution, Slope, etc...) which could be given as multiple results for a given data set collection


(Session proposed by Nick Barcet)

Ceilometer API extensions:

Some enhancements to the API would allow support for a broader set of use cases.
