31.4 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.
