24.1.2  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.
