<div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">
<div>This already exists in trunk. The Notification system was designed specifically to feed billing and monitoring systems. </div>
<div><br>
</div>
<div>Basically, we don't want Nova/Glance/etc to be in the business of trying to determine billing logic, since it is different for pretty much everyone, so we just emit notifications to a queue and the interested pull what they want, and aggregate according
to their own rules. </div>

<div>1. AMQP Client which listen to RabbitMQ / QPid (this should be interchangeable) (Own Stuff or ServiceMix / Camel)</div>

<div>2. Events should be stored on a NoSQL document oriented database (I think mongodb is perfect, since we can query in a super easy fashion)</div>

<div><br>
</div>
<div>We have an existing system called Yagi (<a href="https://github.com/Cerberus98/yagi/">https://github.com/Cerberus98/yagi/</a>) that listens to the notification queues and persists events to a Redis database. It then provides feeds as ATOM formatted documents
that a billing system can pull to aggregate data, It also can support PubSub notification of clients thru the pubsubhubub protocol, and push events to a long-term archiving store thru the AtomPub protocol. </div>
<div><br>
</div>
<div>That said, the notification system outputs its events as JSON, so it should be easy to pipe into a json document-oriented db if that's what you need. (we only use ATOM because we have a atom-based archiving/search/aggregation engine (it's open source: <a href="http://atomhopper.org/">http://atomhopper.org/</a>
) our in-house systems already plug into. )</div>

<div>3a. The monitoring system can pull/push MongoDB</div>
<div><br>
</div>
<div>3b. The billing system can pull to create invoices </div>
<div><br>
</div>
<div>4. A mediation EIP should be necessary to integrate a billing/monitoring product. (ServiceMix / Camel)</div>

<div>This is to receive your feedback. So please, critics are welcome!</div>
