As engineers, we build pretty cool apps. Once users start using our cool apps… well, we run into the fun process of discovering errors. Keeping track of these issues can get messy, getting alerted is stressful, and measuring it can provide you with an overwhelming amount of information.

In this talk, we’ll dive into logging, errors, and metrics, and how to use them to create the ultimate superpower of OBSERVABILITY!
