By default switch sends out syslog to syslog server with all severity levels.
All the messages are stored in the syslog file in /var/log. Users can view it by issuing the “sudo cat syslog” command.
This SONiC CLI command displays all the available log messages.
admin@sonic:~$ show logging
Please use the -f or -follow flag to follow the live logging.
admin@sonic:~$ show logging --follow
