Ryota from NEC presented Ceilometer BP drafts from Doctor project. He primarily introduced fault management scenario, implementation plan in OpenStack, Ceilometer architecture, and how Event Publisher for Alarm and Notification-driven Alarm Evaluator will fill in the gaps in Ceilometer.

The questions focused on technical approach in messaging system. Bryan (AT&T) asked what is the concept of listening, waiting for a response, or subscribed to a channel? Ryota clarified that it meant the subscription to AMQP/RabbitMQ message queue. Bryan indicated that the message queue will not be only internal to OpenStack, and that the technology choice is important for scalability. Ryota clarified that in this context, he is talking about Ceilometer listening internally for events, not external clients consuming events from the OpenStack platform. Bryan emphasized that choice of technology for "listener" is important as this will affect the scalability. we have to consider a variety of dimensions in a generic event notification system for use inside openstack as well as to outside event consumers - TPS is just one, e.g. # of connections, variety of subscribed events, overload protection, etc.

Dave Neary (Redhat) asked how Ryota plans to co-operate with ETSI NFV, and when we can see an updated draft of the blueprint. Ryota confirmed that once the plan is agreed in OPNFV, he would update the blueprint in OpenStack with more details. The purpose here is to seek consensus of this plan.

Bryan indicated that for the Copper blueprints, he would be diving into these aspects under the specs repository per the rough blueprints on the wiki, using the openstack template. Bryan suggested that we ensure that the common goals of doctor and copper re event notification are aligned before we go to openstack (optimally).
