Hey there, it seems to me as if ask.openstack.org is down, so I ask my question here: I'd like to listen to oslo messages from cinder as I do for neutron and octavia to know what is going on. For me the following code worked for neutron: EXCHANGE_NAME = os.getenv('EXCHANGE_NAME', 'neutron') ROUTING_KEY = os.getenv('ROUTING_KEY', 'notifications.info') QUEUE_NAME = os.getenv('QUEUE_NAME', 'messaging_queue') BROKER_URI = os.getenv('BROKER_URI', 'UNDEFINED') BROKER_PASSWORD = os.getenv('BROKER_PASSWORD', '') class Messages(ConsumerMixin): def __init__(self, connection): self.connection = connection return def get_consumers(self, consumer, channel): exchange = Exchange(EXCHANGE_NAME, type="topic", durable=False) queue = Queue(QUEUE_NAME, exchange, routing_key=ROUTING_KEY, durable=False, auto_delete=True, no_ack=True) return [consumer(queues=[queue], callbacks=[self.on_message])] def on_message(self, body, message): try: print(message) except Exception as e: log.info(repr(e)) if __name__ == "__main__": log.info("Connecting to broker {}".format(BROKER_URI)) with BrokerConnection(hostname=BROKER_URI, userid='messaging', password=BROKER_PASSWORD, virtual_host='/'+EXCHANGE_NAME, heartbeat=4, failover_strategy='round-robin') as connection: Messaging(connection).run() BrokerConnection.connection.close() But on the cinder vhost (/cinder) I can't find an exchange that the code is working on. (cinder, cinder-backup, .) I tried using the rabbitmq tracer: <https://www.rabbitmq.com/firehose.html> https://www.rabbitmq.com/firehose.html And got all the cinder messages but I don't want to use it in production because of performance issues. Does anyone have an idea how to find the correct exchange for the notification info queue in cinder? Cheers, Merlin
