This is why we make it possible for all queries to go to the slow query logs with Percona patches :) Right… This is why we make it possible for all queries to go to the slow query logs with Percona patches

With a simple script that runs every minute it is possible to get a real-time statistics of tables that are locked and thus determine candidates for storage engine change or other optimizations. Somehow it is better than slow logs, because slow logs provides information not in real time and only about long queries, however fast queries can also affect performance.
