Follow up from this question, LogBack Syslog not working java
I use command below to view syslog
in ubuntu
16.04 but get below result. Is it the correct way to view?

Looks like you are trying to read syslog
from Java, not from an interactive terminal. The text looks like a correct output, but with smashed formatting.
tail -f
is good for interactive terminals.
Try cat /var/log/syslog
, or just open /var/log/syslog
as a file (if your process has enough permissions).
