Logging and Errors and Metrics, Oh My!

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. So, how do we combine all these things to make our cool apps work even better than before? In this talk, Sentry Dev Evangelist Chloe Condon dives into logging, errors, and metrics (oh my!).

Everything is Broken and I Don't Know Why

We all have someone on our team who writes code with bugs in it. Not us, of course, but someone else. This code somehow gets into production and this code just maybe sometimes crashes. How can we detect these issues and extract useful information at runtime so we can fix these bugs? What kind of stuff should we even be looking for? Sentry developer Matt Robenolt discusses these questions in this talk from JSConf. He’s given versions of this presentation multiple times since.
