Outputting log information to a Linux log host
Network requirements
Configure the device to send log information that has a severity level of at least informational to the Linux
log host at 1.2.0.1/16.
Figure 19
Network diagram
Configuration procedure
Before the configuration, make sure that the device and the PC can reach each other.
1.
Configure the device:
# 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 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
To avoid outputting unnecessary information, disable the output of log, trap, and debugging
information on the specified channel (
loghost
in this example) before you configure an output rule.
# 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
on
2.
Configure the log host:
a.
Log in to the log host as a root user.
b.
Create a subdirectory named
Device
in directory
/var/log/
, and create file
info.log
in the
Device
directory to save logs of
Device
.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
c.
Edit the file
/etc/syslog.conf
and add the following contents.
# Device configuration messages
local5.info
/var/log/Device/info.log
