The syslog-ng Administrator Guide

The syslog-ng Agent for IBM System i application gives you the ability to filter the system audit journal (QAUDJRN) entries that you want to send to a central log server. This can reduce the amount of network traffic and the type of events you transmit to the server. A complete list is available of log system security audit journal event types that the security administrator can edit the events to suppress transmission to the central log server.
