Fenix external dependencies
Fenix will normally use cold and live migrations. For these to work, Nova service user should be configured to be able to ssh between compute nodes. You may also want to change some other related configuration parameters.
AODH and Ceilometer configuration
When want to utilize the VNF(M)/EM interaction with Fenix, VNF needs to supbscribe to AODH event alarm for 'maintenance.scheduled' type of notifications.
Any service may also want to know when host is added, retired, in maintenance or back from maintenance. For this those services can subscribe to AODH event alarm for 'maintenance.host' type of notification.
- event_type: maintenance.scheduled traits: actions_at: fields: payload.maintenance_at type: datetime allowed_actions: fields: payload.allowed_actions host_id: fields: payload.host_id instances: fields: payload.instances metadata: fields: payload.metadata project_id: fields: payload.project_id reply_url: fields: payload.reply_url session_id: fields: payload.session_id state: fields: payload.state - event_type: maintenance.host traits: host: fields: payload.host project_id: fields: payload.project_id session_id: fields: payload.session_id state: fields: payload.state
For AODH and Ceilometer configuration to take into effect, you may want to restart corresponding services
$ sudo systemctl restart openstack-aodh-listener.service $ sudo systemctl restart openstack-ceilometer-notification.service
In DevStack you may want to enable Ceilometer and AODH in local.conf
