What You Need To Know

The following terms and concepts may help as you read this chapter.

Alerts and Logs

An alert is a type of log that warrants more serious attention. They include system errors, attacks

(access control) and attempted access to blocked web sites. Some categories such as

System

Errors

consist of both logs and alerts. You may differentiate them by their color in the

View Log

screen. Alerts display in red and logs display in black.

Syslog Overview

The syslog protocol allows devices to send event notification messages across an IP network to

syslog servers that collect the event messages. A syslog-enabled device can generate a syslog

message and send it to a syslog server.

Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related

information of syslog messages. Each syslog message has a facility and severity level. The syslog

facility identifies a file in the syslog server. Refer to the documentation of your syslog program for

details. The following table describes the syslog severity levels.
