Yeah, the notifications.info queue is the default nova notification queue,
and ceilometer use ceilometer.notifications queue. ceilometer.notifications
queue has 20 consumers and notifications.info queue has 0 consumer:

suo at ustack:~/devstack$ sudo rabbitmqctl list_queues name messages consumers
| grep notifications
name  messages consumers
ceilometer.notifications 0 20
notifications.info 26 0
