Sending System Log Messages to the Log Buffer

If configured as an output destination, the log buffer serves as a temporary storage location for system
log messages. New messages are appended to the end of the listing. When the buffer is full, that is, when
the buffer wraps, old messages are overwritten as new messages are generated, unless you configure the
security appliance to save the full buffer to another location.
