I need to run the slow query and unindexed query logging for some time on a live production db with replication. Changing GLOBAL const value sounds like a good solution. This article also provides good read on that..
The problem is that I need to run FLUSH LOGS; on the master / slave. And I'm not sure how that will effect the replication. Can someone tell me the impact of running FLUSH LOGS; on live master and on live slave.
Thanks
