H3C S3100 Series Ethernet Switches Chapter 1 Information Center

Note:
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.
Note:
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.
1.4.2 Log Output to a Linux Log Host
I. 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”.
