Developer, Operations

"It's just a log, right?" How hard can it be, how can you possibly mess this up?

Wrong. Logs can impact your reliability, performance and quality of sleep in a million ways small and large. In this session we'll cover some of the lessons every engineer should know (and often learns the hard way), such as why good logging solutions are so expensive, why treating your logs as strings can be costly and dangerous, how logs can impact code efficiency and add/fix/change race conditions in your code. And what's the difference between a log line and an event, anyway?

We'll talk about how to craft a good, helpful log line or event and how to spot a bad one. We'll also talk about trends in debugging for complex systems, like the drive for structured logs/events and what comes next.
