R3303-HP HSR6800 Routers Network Management and Monitoring Configuration Guide

In this configuration, local4 is the name of the logging facility that the log host uses to receive
logs. info is the informational level. The UNIX system records the log information that has a
severity level of at least informational to the file /var/log/Router/info.log.
NOTE:
Be aware of the following issues while editing file /etc/syslog.conf:
• Comments must be on a separate line and must begin with a pound sign (#).
• No redundant spaces are allowed after the file name.
• The logging facility name and the information level specified in the /etc/syslog.conf file must be
identical to those configured on the router by using the info-center loghost and info-center source
commands. Otherwise the log information might not be output properly to the log host.
d. Display the process ID of syslogd, kill the syslogd process, and then restart syslogd using the –r
option for the configuration to take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
Now, the system can record log information into the log file.

Configuration procedure
Before the configuration, make sure the router and the log host can reach each other. (Details not shown.)
1. Configure the router:
# Enable the information center.
<Sysname> system-view
[Sysname] info-center enable
# Specify the host 1.2.0.1/16 as the log host, use the channel loghost to output log information
(optional, loghost by default), and specify local5 as the logging facility.
[Sysname] info-center loghost 1.2.0.1 channel loghost facility local5
# Configure an output rule to output to the log host the log information that has a severity level of
at least informational.
[Sysname] info-center source default channel loghost log level informational state
