from Ceilometer POV, currently, raw notifications are optionally stored (for auditing, postmortem analysis, etc...) but they are not queryable from the api (we don't support it as the performance will [arguably] suffer depending on the backend).

the basic structure of an Event in Ceilometer is: id, timestamp, event_type, a list of traits (queryable k/v pairs pulled from notification), and raw (full json notifications)

in Liberty, we intend on support action/alerting on events so maybe it's something we should collaborate on to ensure the right functionality is provided.
