# Octavia API Auditing

The keystonemiddleware audit middleware supports delivery of Cloud Auditing Data Federation (CADF) audit events via Oslo messaging notifier capability. Based on notification_driver configuration, audit events can be routed to messaging infrastructure (notification_driver = messagingv2) or can be routed to a log file (notification_driver = log).

More information about the CADF format can be found on the DMTF Cloud Auditing Data Federation website.

Audit middleware creates two events per REST API interaction. First event has information extracted from request data and the second one has request outcome (response).

## Configuring Octavia API Auditing

Auditing can be enabled by making the following changes to the Octavia configuration file on your Octavia API instance(s).

1. Enable auditing:

       [audit]
       ...
       enabled = True

2. Optionally specify the location of the audit map file:

       [audit]
       ...
       audit_map_file = /etc/octavia/octavia_api_audit_map.conf

   The default audit map file location is /etc/octavia/octavia_api_audit_map.conf.

3. Copy the audit map file from the octavia/etc/audit directory to the location specified in the previous step. A sample file has been provided in octavia/etc/audit/octavia_api_audit_map.conf.sample.

4. Optionally specify the REST HTTP methods you do not want to audit:

       [audit]
       ...
       ignore_req_list =

5. Specify the driver to use for sending the audit notifications:

       [audit_middleware_notifications]
       ...
       driver = log

   Driver options are: messaging, messagingv2, routing, log, noop

6. Optionally specify the messaging topic:

       [audit_middleware_notifications]
       ...
       topics =

7. Optionally specify the messaging transport URL:

       [audit_middleware_notifications]
       ...
       transport_url =

8. Restart your Octavia API processes.
