 * The `qdr::router_id` configuration is to override the default value which uses the fully-qualified domain name (FQDN) of the host. In some cases the FQDN can result in a router ID length of greater than 61 characters which results in failed QDR connections. For deployments with shorter FQDN values this is not necessary.
 * The `resource_registry` configuration directly loads the collectd service because you do not include the `collectd-write-qdr.yaml` environment file for multiple cloud deployments.

 * Set `topic` value of `CeilometerQdrMetricsConfig.topic` to define the topic for Ceilometer metrics. The value is a unique topic identifier for the cloud such as `cloud1-metering`.
 * Set `CollectdAmqpInstances` sub-parameter to define the topic for collectd metrics. The section name is a unique topic identifier for the cloud such as `cloud1-telemetry`.
