Syslog
This chapter explains the syslog screens.
48.1  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.
