Enable Object Storage meters for Red Hat Enterprise Linux and CentOS

Telemetry uses a combination of polling and notifications to collect Object Storage meters.


Your environment must include the Object Storage service.


The Telemetry service requires access to the Object Storage service using the ResellerAdmin role. Perform these steps on the controller node.

  1. Source the admin credentials to gain access to admin-only CLI commands.

    $ . admin-openrc
  2. Create the ResellerAdmin role:

    $ openstack role create ResellerAdmin
    | Field     | Value                            |
    | domain_id | None                             |
    | id        | 462fa46c13fd4798a95a3bfbe27b5e54 |
    | name      | ResellerAdmin                    |
  3. Add the ResellerAdmin role to the ceilometer user:

    $ openstack role add --project service --user ceilometer ResellerAdmin


    This command provides no output.

Install components

  • Install the packages:

    # yum install python-ceilometermiddleware

Configure Object Storage to use Telemetry

Perform these steps on the controller and any other nodes that run the Object Storage proxy service.

  • Edit the /etc/swift/proxy-server.conf file and complete the following actions:

    • In the [filter:keystoneauth] section, add the ResellerAdmin role:

      operator_roles = admin, user, ResellerAdmin
    • In the [pipeline:main] section, add ceilometer:

      pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging ceilometer proxy-server
    • In the [filter:ceilometer] section, configure notifications:

      paste.filter_factory = ceilometermiddleware.swift:filter_factory
      control_exchange = swift
      url = rabbit://openstack:RABBIT_PASS@controller:5672/
      driver = messagingv2
      topic = notifications
      log_level = WARN

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

Finalize installation

  • Restart the Object Storage proxy service:

    # systemctl restart openstack-swift-proxy.service
