36.1 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.
Table 114 Syslog Severity Levels
CODE SEVERITY
0 Emergency: The system is unusable.
1 Alert: Action must be taken immediately.
2 Critical: The system condition is critical.
3 Error: There is an error condition on the system.
4 Warning: There is a warning condition on the system.
5 Notice: There is a normal but significant condition on the system.
6 Informational: The syslog contains an informational message.
7 Debug: The message is intended for debug-level purposes.
