Just an idea of what could be useful to see in pt-stalk.
Sometimes due to mysql optimizer misbehavior queries might be executed using wrong indexes which causes them to run slow. It's usually hard to catch this. It would be cool if pt-stalk can save explain details for running queries like described here: https://www.percona.com/blog/2015/06/18/getting-explain-information-already-running-queries-mysql-5-7/
