Extended stats filtering

This session will include the following subject(s):

Extended stats filtering:

Nowadays user can get 4 statistics for a given metric: max, min, avg and sum. Generally speaking, there are a lot more of potentially interesting aggregates to be calculated for the given metrics. As the first step I would like to propose to add filtering capabilities for existing statistics. This feature would provide user with ability to provide criteria to select the events that would influence counters. Here are few examples of the use cases:
1. Ceilometer may provide statistics about instances booted from the concrete image
2. Statistics for instances colocated in subnet

Also It would be good if user will be able to dynamically create such filters and combine several metrics together.

(Session proposed by Nadya Privalova)

Improving Ceilometer API query filtering:

The current version of Ceilometer API supports a simple query filtering option with a logical AND relation between the fields. This solution results in multiple calls towards the API, when there is a list of requested elements (samples or statistics). The API can be improved to support lists in the fields of a query filter.

This improvement makes it possible to retrieve the samples of one or more meters for one or more resources in one API call and also supports to get the statistics of multiple resources with a single API request.
