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

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.
