Observability Summit North America 2026

The OpenTelemetry Collector has emerged as one of the project’s most critical pieces for ingesting and processing your app and infrastructure data, but did you know there’s even more you can do with your data before it reaches your backend?

Enter OTTL, or OpenTelemetry Transformation Language, a domain-specific language that can interact with and modify OTel data. Yes, the Collector already comes with dozens of components that can handle a wide range of data processing, BUT using OTTL in conjunction with the components enables even more powerful data manipulation.

In this session, learn about the benefits of OTTL, when to use it, and how to get started with OTTL. Get ready to explore:
* What OTTL is: A breakdown of the syntax and the underlying architecture within the OTel Collector.
* Why it’s useful: practical strategies for cost reduction (filtering noise), compliance (redacting PII), and standardization (normalizing attributes).
* How to use it: A live walkthrough of writing complex transformation statements for the transform and filter processors.
