Doug, Deepak,
I am also in the process of implementing a blueprint which allows one
to easily add a dispatcher to do whatever you want to do for each meter
received by Ceilometer. Here is the link to blueprint and the
implementation.https://blueprints.launchpad.net/openstack/?searchtext=multi-dispatcher-enablement https://review.openstack.org/#/c/34301/ If this gets merged soon, you will only need to write something like dispatcher_log.py, in method record_metering_data you may choose to do whatever you like to do with the meter data. For your question #1, you can simple fire up a text message or send out an email if you prefer. Even though you can do whatever you want to do there, but make sure the method is extremely light weight and effecient. Thanks.

Have been working on openstack for just couple weeks and hence have a couple of questions: 1). I read in the documentation that the only way to access the data generated by collector is through the API(i.e either use the cURL option or the ceilometer pythonclient to query the required information). I am able to do this and fetch the required data. However, for an application to access these, is there a better way? Like, whenever the ceilometer generates an event entry in the db, does it provide any notification on any queues, or is there a way we can configure this to happen? If there is no such option, I plan to periodically poll the ceilometer through API for the usage data. (which I sincerely feel is a bad idea). 2). From the Havana roadmap, I see an objective "Publish meters to other systems" Does this mean, other systems can configure to bind themselves on an AMQP queue and ceilometer would publish notifications on this exchange? If so, this would be a feature of Havana? Because I was confused with the publisher feature of Grizzzly, as below Would be great if someone can help me on this. The architecture of ceilometer supports plugging in different publishers. We have one that reproduces the grizzly/folsom feature of sending data on the message bus so the collector can receive it. We also have one that sends UDP messages that are consumed by the collector (useful for monitoring, but not for metering). The API is designed to allow you to write your own if you have a custom consumer, and we would welcome other reusable publishers in the core code base.
