How can I enable MySQL's slow query log without restarting MySQL?

Question

I followed the instructions here: http://crazytoon.com/2007/07/23/mysql-changing-runtime-variables-with-out-restarting-mysql-server/ but that seems to only set the threshold

Answer 1

Find log enabled or not?

SHOW VARIABLES LIKE '%log%';

Set the logs:-

SET GLOBAL general_log = 'ON'; 

SET GLOBAL slow_query_log = 'ON';
