Getting OTTL Right - Testing and Debugging OpenTelemetry Collector Data Transformations

Learn to master testing and debugging OpenTelemetry Transformation Language (OTTL) statements in this lightning talk from KubeCon + CloudNativeCon. Discover how to effectively write, test, debug, and fix OTTL statements using the OpenTelemetry Collector's built-in tools and the OTTL Playground (https://ottl.run). Explore common challenges when OTTL statements don't work as expected and understand how data is interpreted and manipulated under the hood. Examine OTTL and processors closely through real-world examples that demonstrate how debugging tools can reveal hidden issues, explain unexpected behavior, and guide you toward effective solutions. Watch live demonstrations featuring debug logs, intentional mistakes, and practical troubleshooting techniques to build confidence in validating and fine-tuning OTTL statements. Gain essential observability skills as OTTL becomes the standard for shaping telemetry data in the OpenTelemetry Collector, with actionable tips to make future troubleshooting sessions more efficient and effective.
