I'm trying to find out information to make an application that consumes the compute info, but I'm having some trouble. Is there a better documentation I could follow and the precise details of the queue/exchange/routing_key needed to take information at the end of each run-instance and terminate-instance?
Also, I'm using amqplib and I saw that Openstack uses an internal library named Carrot that uses amqplib. Would it be better to use it instead?
