Currently product docs [1] only mention how to enable audit logging and says there are 3 types of access logged: NATIVE, HTTP and JMX. However, the JMX audit logs must be set separately and are not enabled by default. I find the current docs misleading as it mentions JMX audit logs without saying they must be configured first.
