22.1.2 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.
