Sandy, Thanks for your comprehensive report card and detailed explanation! That helps a lot! I'll follow the route of using Yagi for now.

Re: [openstack-dev] [TripleO][Nova][neutron][Heat][Oslo][Ceilometer][Havana]Single Subscription Point for event notification
(Sorry for the top-post ... web client) So long as you configure each of the services to publish on the same notification topic [1], they'll all end up in the same queue. Then you can use anything that can consume from that queue to get your messages. Note that there are .info, .error and .warn queues, so notifications.info, notifications.error, etc by default. Ceilometer [2] is the currently blessed service for consuming these notifications, but our event support in it is pretty weak right now (to be fully functional in IceHouse). For something today, you could use StackTach [3] or Yagi [4] to consume these events. Yagi is especially good if you want to forward them to another downstream service. StackTach would be a better choice if you want to poll for events of a certain type.

Re: [openstack-dev] [TripleO][Nova][neutron][Heat][Oslo][Ceilometer][Havana]Single Subscription Point for event notification
Hi, I am not sure that there is an existing service or API for event subscription. The event management was listed as a part of Mistral project which is not implemented though. If I am not mistaken, Mistral will allow you to refer events and alarms coming from different sources and trig some actions\task execution including call of some external hook. Scheduling is also covered by Mistral proposal but it is just an example of some timer based events.
