Outputting Log Information to a Linux Log Host
Network requirements
z Send log information to a Linux log host with an IP address of 1.2.0.1/16;
z Log information with severity higher than informational will be output to the log host;
z All modules can output log information.
Figure 1-3 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.
1) Configure 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 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
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) Configure the log host
Step 1: Log in to the log host as a root user.
