Note the following items when you edit file “/etc/syslog.conf”.

zA note must start in a new line, starting with a “#" sign.

zIn each pair, a tab should be used as a separator instead of a space.

zNo space is permitted at the end of the file name.

zThe device name (facility) and received log information severity specified in file “/etc/syslog.conf” must be the same with those corresponding parameters configured in commands info-center loghost and info-center source. Otherwise, log information may not be output to the log host normally.

Step 3: After the log file “information” is created and the file “/etc/syslog.conf” is modified, execute the following commands to view the process ID of the system daemon “syslogd”, stop the process, and then restart the daemon "syslogd" in the background with the “-r” option.

#ps -ae grep syslogd 147

#kill -9 147

#syslogd -r &

In case of Linux log host, the daemon “syslogd” must be started with the “-r” option.

After all the above operations, the device can record information in the corresponding log file.

Through combined configuration of the device name (facility), information severity level threshold (severity), module name (filter) and the file “syslog.conf”, you can sort information precisely for filtering.
