1) Configuring the device
# Enable information center.
<Sysname> system-view
[Sysname] info-center enable
# Specify the host with IP address 1.2.0.1/16 as the log host, use 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
# Disable the output of log, trap, and debugging information of all modules on the channel loghost.
[Sysname] info-center source default channel loghost debug state off log state off trap state
off
As the default system configurations for different channels are different, you need to disable the output
of log, trap, and debugging information of all modules on the specified channel (loghost in this example)
first and then configure the output rule as needed so that unnecessary information will not be output.
# Configure the information output rule: allow log information of all modules with severity equal to or
higher than informational to be output to the log host.
[Sysname] info-center source default channel loghost log level informational state on
2) Configuring the log host
Step 1: Issue the following commands as a root user.
# mkdir /var/log/MyDevice
# touch /var/log/MyDevice/information
Step 2: Edit the file /etc/syslog.conf as a root user and add the following selector/action pair.
# MyDevice configuration messages
local7.info /var/log/MyDevice/information
Be aware of the following issues while editing the /etc/syslog.conf file:
z
Comments must be on a separate line and must begin with the # sign.
z
The selector/action pair must be separated with a tab key, rather than a space.
z
No redundant spaces are allowed in the file name.
z
The device name and the accepted severity of the log information specified by the /etc/syslog.conf
file must be identical to those configured on the device using the info-center loghost or
info-center source command; otherwise the log information may not be output properly to the log
host.
Step 3: After the log file information has been created and the /etc/syslog.conf file has been modified,
issue the following commands to display the process ID of syslogd, terminate a syslogd process, and
restart syslogd using the -r option.
