Operation Manual – Information Center
Quidway S3900 Series Ethernet Switches-Release 1510
Note:
Note the following items when you edit file "/etc/syslog.conf".
A note must start in a new line following a "#" sign.
In each pair, a tab should be used as a separator instead of a space.
No space is permitted at the end of the file name.
The 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, run 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 &
Note:
In case of Linux log host, the daemon "syslogd" must be started with the "-r" option.
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 file "syslog.conf", you can sort
information precisely for filtering.
