After reading documentations and code, I would like to know if my understanding is correct.

In Ceilometer:

  1. The compute agent is a polling agent.
  2. The Central Agent is a polling agent.
  3. The notification agent (coded in ceilometer/ceilometer/ listens on the notification bus and transforms events into samples by calling the method process_notification of the notifications_plugins it loaded.
  4. The Collector agent stores the different samples provided either by polling, push or notification agents into the database.

For each statement, could you please tell me if I'm right. If not, could you please explain further?

Thanks beforehand, Romain.
