Configuration procedure
Before the configuration, make sure the device and the log host can reach each other. (Details not
shown.)
1.
Configure the device:
# Enable the information center.
<Device> system-view
[Device] info-center enable
# Specify the log host 1.2.0.1/16, and specify
local5
as the logging facility.
[Device] info-center loghost 1.2.0.1 facility local5
# Disable log output to the log host.
[Device] info-center source default loghost deny
To avoid outputting unnecessary information, disable all modules from outputting log
information to the specified destination (
loghost
in this example) before you configure an
output rule.
# Configure an output rule to enable output to the log host FTP logs that have a severity level of
at least
informational
.
[Device] info-center source ftp loghost level informational
2.
Configure the log host:
The following configurations were performed on Solaris. Other UNIX operating systems have
similar configurations.
a.
Log in to the log host as a root user.
b.
Create a subdirectory named
Device
in the 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
syslog.conf
in directory
/etc/
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 informational level. The Linux system will store the log information
with a severity level equal to or higher than
informational
to the file
/var/log/Device/info.log
.
NOTE:
Follow these guidelines while editing the 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 severity level specified in the
/etc/syslog.conf
file must
be identical to those configured on the device by using the
info
-
center loghost
and
info-center source
commands. Otherwise, the log information might not be output to the
log host correctly.
d.
Display the process ID of
syslogd
, kill the
syslogd
process, and then restart
syslogd
by
using the
-r
option to apply the new configuration.
Make sure the
syslogd
process is started with the
-r
option on a Linux log host.
# ps -ae | grep syslogd
147
# kill -9 147
# syslogd -r &
