When you edit the file “/etc/syslog.conf”, note that:
z A note must start in a new line, starting with a “#” sign.
z In each pair, a tab should be used as a separator instead of a space.
z No space is allowed at the end of a file name.
z The device name (facility) and received log information severity level specified in the file
“/etc/syslog.conf” must be the same as those corresponding parameters configured in the
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 command to send a HUP signal to the system daemon “syslogd”, so that it can reread its
configuration file “/etc/syslog.conf”.
# ps -ae | grep syslogd
147
# kill -HUP 147
After all the above operations, the switch can make records 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.
Log Output to a Linux Log Host
Network requirements
The switch sends the following log information to the Linux log host whose IP address is 202.38.1.10:
All modules' log information, with severity higher than “errors”.
