Notification Listener using Oslo Client

I want to create a notification listener that connects to the Oslo bus and retrieves all the messages passed on by different modules. Currently I am using pika Client for RabbitMQ to listen to the notification. here is the code snippet

queue_name = "name"
credentials = pika.PlainCredentials("username", "password")
connection = pika.blockingConnection(pika.connectionParameters(host = "hostname", credentials = credentials))

def callback(ch,method,properties,body)
# do stuff

channel.basic_consume(callback,queue = queue_name,no_ack = True)


but this only works for RabbitMQ, I want to use Oslo Client to do the same. How can I do that using Oslo Libraries. A simple code snippet can be helpful.

oh I added a logger (logging.basicConfig()) it shows the error now .. the problem now is that it is unable to log in the amqp server. I tried changing the cfg.CONF[rabbit_password], but that didnt help. any idea ?

What is the exact error? Default CONF values should work If you haven't changed anything

rabbit_host=localhost rabbit_port=5672 rabbit_userid=guest rabbit_password=guest

sorry for the delay. I was able to get a workaround for that (passed the url), but the simple notification listener code is creating queues with names *.warn, *.error, that gives me nothing. did this code work for you? can you share a sample snippet (maybe just listening to nova specific queues)
