2. Set the Telemetry service to connect to the RabbitMQ host:

   # openstack-config --set /etc/ceilometer/ceilometer.conf \
      DEFAULT rabbit_host RABBITMQ_HOST

   Copy to Clipboard Toggle word wrap
   Replace RABBITMQ_HOST with the IP address or host name of the message broker.
3. Set the message broker port to 5672:

   # openstack-config --set /etc/ceilometer/ceilometer.conf \
      DEFAULT rabbit_port 5672

4. Set the RabbitMQ user name and password created for the Telemetry service when RabbitMQ was configured:

   # openstack-config --set /etc/ceilometer/ceilometer.conf \
      DEFAULT rabbit_userid ceilometer
   # openstack-config --set /etc/ceilometer/ceilometer.conf \
      DEFAULT rabbit_password CEILOMETER_PASS

   Copy to Clipboard Toggle word wrap
   Replace ceilometer and CEILOMETER_PASS with the RabbitMQ user name and password created for the Telemetry service.
5. When RabbitMQ was launched, the ceilometer user was granted read and write permissions to all resources: specifically, through the virtual host /. Configure the Telemetry service to connect to this virtual host:

   # openstack-config --set /etc/ceilometer/ceilometer.conf \
      DEFAULT rabbit_virtual_host /
