local5.info /var/log/Device/info.log

In the configuration, local5 is the name of the logging facility used by the log host to receive logs, and

info is the information level. The Linux system will record the log information with severity level equal to

or more severe than informational to file /var/log/Device/info.log.

NOTE:

Be aware of the following issues while editing file /etc/syslog.conf:

• Comments must be on a separate line and begin with the pound (#) sign.

• No redundant spaces are allowed after the file name.

• The logging facility name and the information level specified in the /etc/syslog.conf file must be

identical to those configured on the device using the info-center loghost and info-center source

commands. Otherwise the log information may not be output properly to the log host.

Step 4: After log file info.log is created and file /etc/syslog.conf is modified, you need to issue the

following commands to display the process ID of syslogd, kill the syslogd process, and restart syslogd

using the -r option to make the modified configuration take effect.

# ps -ae | grep syslogd

147

# kill -9 147

# syslogd -r &

NOTE:

Make sure that the syslogd process is started with the -r option on a Linux log host.

After the configurations, the system will be able to record log information into the log file.
