Configure

  1. You need to connect an audit filter to the service configuration file to logging actions on objects Nova:

    • Add filter definition to configuration file /etc/nova/api-paste.ini:

      [filter:audit]
paste.filter_factory = nova_journal_middleware.middleware:filter_factory

    • Add created filter to the key keystone in API request processing chain:

      [composite:openstack_compute_api_v21]
use = call:nova.api.auth:pipeline_factory_v21
noauth2 = cors compute_req_id faultwrap sizelimit noauth2 osapi_compute_app_v21
keystone = cors compute_req_id faultwrap sizelimit authtoken keystonecontext audit osapi_compute_app_v21

    • Set up sending notifications to the message queue in the file /etc/nova/nova.conf on the control node and all compute nodes:

      [oslo_messaging_notifications]
driver = messagingv2

  2. Restart nova-api service:

    # Debian:
systemctl restart nova-api.service
