Enable Object Storage meters for Ubuntu¶

Prerequisites¶

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
   

   Note

   This command provides no output.

Install components¶

• Install the packages:

  # apt-get 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:

    [filter:keystoneauth]
    ...
    operator_roles = admin, user, ResellerAdmin
    

  • In the [pipeline:main] section, add ceilometer:

    [pipeline:main]
    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:

    [filter:ceilometer]
    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:

  # service swift-proxy restart
