Figure 3 Network diagram for outputting log information to a Linux log host
Configuration procedure
Before the configuration, make sure that there is a route between Device and PC.
Step1 Configure the device
# Enable information center.
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 use 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 channel loghost.
[Sysname] info-center source default channel loghost debug state off log state off trap
state off
CAUTION:
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
Step2 Configure the log host
Step 1: Log in to the log host as a root user.
Step 2: Create a subdirectory named Device under directory /var/log/, and create file info.log
under the Device directory to save logs of Device.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
Step 3: Edit file /etc/syslog.conf and add the following contents.
# Device configuration messages
local5.info /var/log/Device/info.log
In the above configuration, local5 is the name of the logging facility used by the log host to receive logs.
info is the information level. The Linux system will record the log information with severity level equal to
or higher than informational to file /var/log/Device/info.log.
