Enable Compute service meters

Enable Compute service meters

Telemetry uses a combination of notifications and an agent to collect Compute meters. Perform these steps on each compute node.

Install and configure components

  1. Install the packages:

    # apt-get install ceilometer-agent-compute
  1. Edit the /etc/ceilometer/ceilometer.conf file and complete the following actions:

    • In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

      rpc_backend = rabbit
      rabbit_host = controller
      rabbit_userid = openstack
      rabbit_password = RABBIT_PASS

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

    • In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:

      auth_strategy = keystone
      auth_uri = http://controller:5000
      auth_url = http://controller:35357
      auth_plugin = password
      project_domain_id = default
      user_domain_id = default
      project_name = service
      username = ceilometer
      password = CEILOMETER_PASS

      Replace CEILOMETER_PASS with the password you chose for the Telemetry service database.

    • In the [service_credentials] section, configure service credentials:

      os_auth_url = http://controller:5000/v2.0
      os_username = ceilometer
      os_tenant_name = service
      os_password = CEILOMETER_PASS
      os_endpoint_type = internalURL
      os_region_name = RegionOne

      Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.

    • (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

      verbose = True

Configure Compute to use Telemetry

  • Edit the /etc/nova/nova.conf file and configure notifications in the [DEFAULT] section:

    instance_usage_audit = True
    instance_usage_audit_period = hour
    notify_on_state_change = vm_and_task_state
    notification_driver = messagingv2

Finalize installation

  1. Restart the agent:

    # service ceilometer-agent-compute restart
  2. Restart the Compute service:

    # service nova-compute restart
