[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 properly to the log host.
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 &
Now, the system can record log information into the specified file.
