A Percona Support Engineer Walkthrough on pt-stalk

Wednesday 3:20PM-4:10PM

@ Field Suite 2

MySQL / MariaDB

50 minutes conference


Developer, Operations

As a support engineer, everyday we get dozens of pt-stalk captures from our customers containing samples of iostat, vmstat, top, ps, SHOW ENGINE INNODB STATUS, SHOW PROCESSLIST and a multitude of other diagnostics outputs.

These are the tools of the trade for performance and troubleshooting, and we must learn to digest these outputs in an effective and systematic way to allow us to provide high quality service to a large volume of customers, and that is the knowledge we want to share through this presentation.

We will learn to setup, capture data, write plugins to trigger collection and to capture custom data, look at our systematic approach and learn what data to read first and how to unwind the tangled threads of pt-stalk.

By the end of this presentation you will have expert knowledge on how to capture diagnostic metrics at the right time and will have a generic approach to digest the captured data, allowing you to work on a large number of problems common to MySQL setups.
