[openstack-dev] OpenStack Alarms

I have a general question about alarming in OpenStack.
Service 'ceilometer-alarm-singleton' generates 'Threshold' Alarms based on threshold crossings of the meters it is monitoring.
And service 'ceilometer-alarm-notifier' listens to the RPC bus for Alarm Notification events and executes the defined triggered action(s) for any alarms.
However, a System has more than just meter-based threshold alarms. E.g. a Compute Node Failure, a physical interface failure, etc. .
Is there a "GENERAL" RPC Bus for Alarm Notification Events in OpenStack ?
Is it the one used by Ceilometer ?
Is the intent that Ceilometer is also collecting "ALL" Alarms, storing them in DB, and supporting 'publishers' for Alarms (e.g. an SNMP Trap publisher ) ?
