--- features: - | Adds ability to configure custom fluentd filters. In some scenarios it may be useful to apply custom filters to logs before forwarding them. This may be useful to add additional tags to the messages or to modify the tags to conform to a log format that differs from the one defined by kolla-ansible. Configuration of custom fluentd filters is possible by placing filter configuration files in ``/etc/kolla/config/fluentd/filter/*.conf`` on the control host.
