Re: Notifiers

 

We have been investigating over nova notifications. I really like the Sandy Walsh implementation for Essex SystemUsage Blueprint <http://wiki.openstack.org/SystemUsageData>. You can see the code in Change I33cc9076 <https://review.openstack.org/#change,4194>.

This could be an alternative to glance aproach.

cheers

To make the notifiers common, the QAL / RPC will also have to be made common. The Glance code for notifications currently implements queue/rpc-implementation specific notifiers, so this might not be a bad thing…

If there is an effort to move the RPC into openstack.common, then I would like to be involved, if only as a reviewer to ensure the queue abstraction layer makes it over safely. [I still question if we need an rpc.notify()…]

Hi,

we are thinking to contribute to increase the types of notifications (events) through the rabbit server. We are thinking to notify from each Openstack component (nova, glance, quantum in the future ...)

We think that unify the code on the openstack-common stuff is a great idea.

We are really interested to collaborate on this topic.

Cheers,
Juan

Hi,
I've been playing around with openstack for a month now and was looking to see how I can contribute. I saw that nova and glance use different methods to send out notifications. It looked relatively straight forward to make them use one common library for notifications. That way, when we make changes or add new transports we do not have to do it twice (or more number of times depending on how other components of openstack do notifications). Let me know if someone is already working on this. If not, let me know if this makes sense and I can start by creating a blueprint. Also, is there any preference to use object oriented (or not)?

Cheers,
Venkat
