Enable Compute service meters for openSUSE and SUSE Linux Enterprise¶

Install and configure components¶

1. Install the packages:

   # zypper install openstack-ceilometer-agent-compute
   # zypper install openstack-ceilometer-agent-ipmi (optional)
   

2. Edit the /etc/ceilometer/ceilometer.conf file and complete the following actions:

   • In the [DEFAULT] section, configure RabbitMQ message queue access:

     [DEFAULT]
     ...
     transport_url = rabbit://openstack:RABBIT_PASS@controller
     

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

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

     [service_credentials]
     ...
     auth_url = http://controller:5000
     project_domain_id = default
     user_domain_id = default
     auth_type = password
     username = ceilometer
     project_name = service
     password = CEILOMETER_PASS
     interface = internalURL
     region_name = RegionOne
     

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

Configure Compute to use Telemetry¶

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

  [DEFAULT]
  ...
  instance_usage_audit = True
  instance_usage_audit_period = hour
  notify_on_state_change = vm_and_task_state
  
  [oslo_messaging_notifications]
  ...
  driver = messagingv2
  

Configure Compute to poll IPMI meters¶

• Edit the /etc/sudoers file and include:

  ceilometer ALL = (root) NOPASSWD: /usr/bin/ceilometer-rootwrap /etc/ceilometer/rootwrap.conf *
  

• Edit the /etc/ceilometer/polling.yaml to include the required meters, for example:

  - name: ipmi
    interval: 300
    meters:
      - hardware.ipmi.temperature
  

Finalize installation¶

1. Start the agent and configure it to start when the system boots:

   # systemctl enable openstack-ceilometer-agent-compute.service
   # systemctl start openstack-ceilometer-agent-compute.service
   # systemctl enable openstack-ceilometer-agent-ipmi.service (optional)
   # systemctl start openstack-ceilometer-agent-ipmi.service (optional)
   

2. Restart the Compute service:

   # systemctl restart openstack-nova-compute.service
