Instrumentation is the secret ingredient that brings observability to life, revealing the intricate workings of applications in ways logs and metrics alone can’t match. In this talk, we’ll dive deep into the magic of OpenTelemetry instrumentation, exploring how to uncover hidden insights within your applications and services.

Join us as we break down the essentials of OpenTelemetry instrumentation, including setting up automatic instrumentation for popular libraries and frameworks, and crafting custom spans to track the most critical parts of your workflows. You’ll see how simple, well-placed instrumentation points can reveal complex system behaviors, helping you detect bottlenecks, trace errors, and understand end-to-end request flows.

Whether you’re new to observability or looking to master OpenTelemetry, this session will show you how to harness the full potential of instrumentation to transform your data into actionable insights. Discover the power of OpenTelemetry and bring clarity to your observability journey.
