13.1 Syslog Logs

There are two types of syslog: event logs and traffic logs. The device generates an event log
when a system event occurs, for example, when a user logs in or the device is under attack.
The device generates a traffic log when a "session" is terminated. A traffic log summarizes the
session's type, when it started and stopped the amount of traffic that was sent and received and
so on. An external log analyzer can reconstruct and analyze the traffic flowing through the
device after collecting the traffic logs.

DESCRIPTION
This message is sent by the system ("RAS" displays as the
system name if you haven't configured one) when the router
generates a syslog. The facility is defined in the web MAIN
MENU, LOGS, Log Settings page. The severity is the log's
syslog class. The definition of messages and notes are
defined in the other log tables. The "devID" is the MAC
address of the router's LAN port. The "cat" is the same as
the category in the router's logs.
This message is sent by the device when the connection
(session) is closed. The facility is defined in the Log
Settings screen. The severity is the traffic log type. The
message and note always display "Traffic Log". The "proto"
field lists the service name. The "dir" field lists the incoming
and outgoing interfaces ("LAN:LAN", "LAN:WAN",
"LAN:DMZ", "LAN:DEV" for example).
This message is sent by the device ("RAS" displays as the
