[Openstack] Ceilometer-collector does not receive anything

Hi all,
thanks a lot for your answers.
We know that ceilometer is not able to receive notifications from openstack
components (like nova), when installed with XCP. But both our goal and
testing approach are different. The strange behaviour we are talking about
concerns ceilometer-collector and it's usage of kombu for AMQP. We added
debugging output in
ceilometer.openstack.common.rpc.impl_kombu.ConsumerBase.consume._callback
to see whether or not some of the 58 topic consumers would receive anything
on their exchange and topic. For that purpose we wrote a small test
programm to publish a simple message on a configured exchange and topic to
see a reaction from ceilometer-collector, but we received nothing. The
rabbitmq server itself is working fine, as we can consume our sent message
with another small test programm. We think this might be a configuration
issue, but we've been through our setup several times and can't find the
issue.
here are the source codes of the our test programs (publisher and consumer).
---publisher----
import pika
import logging
AMQP_HOST="ip"
AMQP_USERNAME="username"
AMQP_PASSWORD="passwd"
AMQP_EXCHANGE="openstack"
AMQP_ROUTING="notifications"
class AMQPSender(object):
"""docstring for AMQPSender"""
def __init__(self):
super(AMQPSender, self).__init__()
self.connection = pika.BlockingConnection(pika.ConnectionParameters(
host=AMQP_HOST,
credentials=pika.PlainCredentials(
username=AMQP_USERNAME,
password=AMQP_PASSWORD)))
self.channel = self.connection.channel()
self.channel.exchange_declare(exchange=AMQP_EXCHANGE, type='topic')
def send(self, msg):
self.channel.basic_publish(exchange=AMQP_EXCHANGE,
routing_key=AMQP_ROUTING,
body=msg)
def close(self):
self.connection.close()
logging.basicConfig()
a = AMQPSender()
a.send("Hallo Welt")
a.close()

self.channel = self.connection.channel()
self.channel.exchange_declare(exchange=AMQP_EXCHANGE, type='topic')
result = self.channel.queue_declare(exclusive=True)
self.queue_name = result.method.queue
self.channel.queue_bind(exchange=AMQP_EXCHANGE,
queue=self.queue_name,
routing_key=AMQP_ROUTING)
def recv(self):
def callback(ch, method, properties, body):
print " [x] %r:%r" % (method.routing_key, body,)
self.channel.basic_consume(callback,

Thank you
