==== Jourald for System Logs and JSON File for Container Logs

Docker log driver is set to `json-file` as the default for all nodes. Docker
`log-driver` can be set to `journal`, but there is no log rate throttling with
journal driver. So, there is always a risk for denial-of-service attacks from
rogue containers.

Fluentd will automatically determine which log driver (`journald` or
`json-file`) the container runtime is using. Fluentd will now always read logs
from journald and also *_/var/log/containers_* (if `log-driver` is set to
`json-file`). Fluentd will no longer read from *_/var/log/messages_*.

See
xref:../install_config/aggregate_logging.adoc#install-config-aggregate-logging[Aggregating
Container Logs] for more information.
