ceilometer-agent-compute is not connected to AMQP on initial deployment of new compute nodes in Red Hat OpenStack Platform

Solution In Progress - Updated -


New compute nodes were added to the cloud (scale out). ceilometer-agent-compute is not connected to rabbitmq after deployment of these compute nodes.

The following script is being used to verify that the service properly connects to AMQP

def check_process_exists_and_amqp_connected(name):
    processes = filter(lambda p: check_process_name(name, p),
    if not processes:
        critical("%s is not running" % name)
    for p in processes:
            connections = p.get_connections(kind='inet')
        except psutil.NoSuchProcess:
        found_amqp = (
            len(list(itertools.takewhile(lambda c:
                len(c.remote_address) <= 1 or
                c.remote_address[1] != AMQP_PORT,
                connections))) != len(connections))
        if found_amqp:
            ok("%s is working." % name)
    critical("%s is not connected to AMQP" % name)

netstat shows that there is no ESTABLISHED connection from ceilometer to rabbitmq.

On the other hand, netstat reveals that e.g. nova-compute on the same compute node can connect to AMQP quite fine

Also, ceilometer logs look clean on this new compute node.
