OpenShift audit works at the API server level, logging all requests coming to the server.
Audit is on by default and the best practice is to ship audit logs off the cluster for retention
using a secure protocol.
The cluster-logging-operator is able to do this with the
ClusterLogForwarders
resource.
The forementioned resource can be configured to logs to different third party systems.
