Architecture
REST resource
The new solution includes new REST resources for provide complex queries for sample statistics:
| REST Resource | Functionality | Returned Object Type |
|---|---|---|
| '/query/samples/statistics' | retrieve statistics of samples for meter(s) | Statistics |
As new resource is defined, the simple statistics query support remained as it is now, which means that the API is backward compatible and also a new query grammar could be defined without limitations.
POST request
Filter Expression Language
The same expression language is used as in Ceilometer/ComplexFilterExpressionsInAPIQueries#Filter_Expression_Language
