Mitaka Series Release Notes
- The options `requeue_event_on_dispatcher_error’ and `requeue_sample_on_dispatcher_error’ have been enabled and removed.
- The previous configuration options default for `requeue_sample_on_dispatcher_error’ and `requeue_event_on_dispatcher_error’ allowed to lose data very easily: if the dispatcher failed to send data to the backend (e.g. Gnocchi is down), then the dispatcher raised and the data were lost forever. This was completely unacceptable, and nobody should be able to configure Ceilometer in that way.”
