Step 2: Edit the file “/etc/syslog.conf” as the super user (root user) to add the following
selector/action pairs.
# H3C configuration messages
local4.info /var/log/H3C/information
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 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 read its new 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 in English to the Linux log host whose IP
address is 202.38.1.10: All modules' log information, with severity higher than “errors”.
