To avoid output of unnecessary information, disable all modules from outputting logs to the
specified destination (
loghost
in this example) before you configure an output rule.
# Configure an output rule to 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 directory
/var/log/
, and then create file
info.log
in
the
Device
directory to save logs from
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
local4.info /var/log/Device/info.log
In this configuration,
local4
is the name of the logging facility that the log host uses to
receive logs.
info
is the informational level. The UNIX system records the log information
that has a severity level of at least
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
using
the
–r
option to make the new configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
Now, the device can output FTP logs to the log host, which stores the logs to the specified file.

Network requirements
Configure the device to output to the Linux log host 1.2.0.1/16 FTP logs that have a severity level of
at least
informational
