Detective Hat: Investigating Production Bugs
It was a dark and stormy night, and our production system was out cold. It was our job to find out what had gone wrong and set it right. But how? Our developer-instincts weren't helping. Our tester's-intuition saw risk everywhere. We needed a third way; the hard-nosed, boots on the ground, skeptical mindset of the detective! Jenny Bramble, Director of Quality Engineering, and Adrian P. Dunston, Director of Backend Engineering at Papa will give you a powerful mental model for tracking down production issues in your codebase and a set of tools to help you along the way. Using noir and tv-detective stories as a backdrop, you'll learn how to: take ownership for a production behavior, hit the streets to find the relevant facts and metrics, confront any hard truths you may find, bring your tools to bear, and follow through to make production a better place for everyone. With the detective mindset, grit, and determination you can go beyond sleuthing out your systems' behaviors. You'll build better paths to observability and better processes to prevent and recover production incidents. You might even help your colleagues find detective hats of their own.
