Syslog
This chapter explains the syslog screens.
40.1  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.
