You’ve heard about OpenTelemetry, and now it’s time to give it a shot. Instrumenting your services was easy—until it wasn’t. You got some traces flowing into your observability backend, but as soon as you started adding custom spans and attributes, the real questions began.

Should you create spans for every single method/function in your code? Is more always better? What attributes should you add to your spans? Maybe include full JSON payloads, or go all out and add a whole PDF as an attribute? (Spoiler: don’t.)

Join Juliano in this talk to learn best practices for customizing your application instrumentation with OpenTelemetry. Discover how to make the most of your telemetry while ensuring usability, cost efficiency, and performance. Whether you're just starting out or fine-tuning your instrumentation, this session will help you get to the right balance, avoid costly mistakes, and walk away with clear strategies to get the most out of your telemetry.
