Some categories such as System Errors consist of both logs and alerts. 11.1.2 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.

Logs
Use these screens to look at log entries and alerts and to configure the P-2024’s log and alert
settings.
11.1
Logs Overview
For a list of log messages, see
Section 11.3 on page 110
.
11.1.1
Alerts
An alert is a type of log that warrants more serious attention. Some categories such as
System
Errors
consist of both logs and alerts.
11.1.2
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.
