■
The device
name and
the acceptant log information level specified in /etc/syslog.conf must be consistent
with info-center loghost and info-center loghost a.b.c.d facility configured on
the switch. Otherwise, the log information probably cannot be output to the
loghost correctly.
c After the establishment of information (log file) and the revision of
/etc/syslog.conf
, you should send a HUP signal to syslogd (system daemon),
through the following command, to make syslogd reread its configuration file
/etc/syslog.conf
.
# ps -ae | grep syslogd
147
# kill -HUP 147
After the above operation, the switch system can record information in related log
files.
To configure facility, severity, filter and the file syslog.conf synthetically, you can
get classification in great detail and filter the information.
