This is for my reference as i've been setting this up locally on OSX but should work for Windows and Linux and it might help someone else.
To find your log location run the following
SHOW VARIABLES LIKE '%general_log%';
SHOW VARIABLES LIKE '%slow_query_log%';
You'll get something back like this
general_log ON
general_log_file /usr/local/mysql/data/localhost.log
slow_query_log ON
slow_query_log_file /usr/local/mysql/data/localhost-slow.log
With this info and the terminal (for *nix based machines) you can output the logs with tail and
$ tail -f -n1000 /usr/local/mysql/data/localhost.log
If any of the logs are off you can turn them on again via
SET GLOBAL general_log = 'ON';
SET GLOBAL slow_query_log = 'ON';
