In the above configuration,
local5
is the name of the logging facility used by the log host to receive logs.
info
is the information level. The Linux system will record the log information with severity level equal to
or higher than
informational
to file
/var/log/Device/info.log

and
info-center source
commands; otherwise the log information may not be output properly to the log host.
Step 4: After log file
info.log
is created and file
/etc/syslog.conf
is modified, you need to issue the
following commands to display the process ID of
syslogd
, kill the
syslogd
process, and restart
syslogd
using the
-r
option to make the modified configuration take effect.
# ps -ae | grep syslogd
147
# kill -9 147
# syslogd -r &
Ensure that the
syslogd
process is started with the -r option on a Linux log host.
After the above configurations, the system will be able to record log information into the log file.
