We are using Havana OpenStack version. Would like to write a listener ( in java ) which can subscribe for OpenStack Notifications /Events like events like Server(VM), Network,Subnet,Port – creation/deletion/update and Server(VM) power state changes.
I understand that OpenStack uses RabbitMQ internally for pub/sub. Can I have some reference to notification message format, event types etc.. and how I can subscribe to it these kind of events ?
If there is any example written in python also would help.
