How do I check the TURN Server logs?

Question

I have installed the open source TURN server(rfc5766-turn-server), I run it using the following command sudo turnserver -L my.domain.in -a -b /usr/local/etc/turnuserdb.conf -f -r domain.in

This is the output I get in terminal,

when a client is connected or using this TURN server, will I get any log in my terminal or anywhere else?

Also this is an very old question, I think it is still not properly answered yet! There are indeed log files under var/log/ but they are not very helpful.

CoTurn logs to the syslog! So you need to run

cat /var/log/syslog | grep turnserver

to see what is happening.
