3.8.5. About a Management Interface Audit Logging Syslog Handler
A syslog handler specifies the parameters by which audit log entries are sent to a syslog server, specifically the syslog server's hostname and the port on which the syslog server is listening.
Sending audit logging to a syslog server provides more security options than logging to a local file or local syslog server. Multiple syslog handlers can be defined.
Syslog servers vary in their implementation, so not all settings are applicable to all syslog servers. Testing has been conducted using the rsyslog syslog implementation.
