</div><div><br></div><div>Dough had mixed reviews during the session, but that I think was because it came across as a billing system triggered solely by Horizon requests and was a polled architecture. Given what we have today, I'd implement my own billing/metering system exactly the same way. In fact, I have. Our own e-commerce system at Nimbis works this way with EC2 and OpenStack presently because the only option available is polling periodically and logging the usage data.</div>
</div><div><br></div><div>Where I'd like to see OpenStack go is metering service that is fully asynchronous and event driven so that I only need to hit the API service when I'm generating an invoice, rather than once per minute because I don't know when an instance was terminated by the user or just crashed. </div>

<div><br></div><div>We collectively need to talk more about the user scenarios, because I don't think you can just put a decorator around the API rpc calls and get an accurate picture of what to bill for later. There are metered things like bandwidth or IOPS, events that happen outside of the API (shutdown -h), and it is hard to predict what a reseller will want to charge for. It is better to put a metering system in that can handle many billing configurations.</div>

Hi,<div><br></div><div>I want to share the architecture i am developing in order to perform the monitorig / billing OpenStack support:</div><div><br></div><div>1. AMQP Client which listen to RabbitMQ / QPid (this should be interchangeable) (Own Stuff or ServiceMix / Camel)</div>
<div><br></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>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><br></div>
