OTTL Me Why Transforming Telemetry in the OpenTelemetry Collector Just Got Better - Tyler Helmuth, Honeycomb & Evan Bradley, Dynatrace

As the observability ecosystem rapidly grows in size, choices, and maturity, it's not uncommon to find yourself in situations where your data doesn't look how you expect: it's too large, the wrong shape, or doesn't have everything you want. Enter the OpenTelemetry Collector, an observability pipeline that can receive, process, and export telemetry data at scale. In order to facilitate processing telemetry in a standard way, the Collector uses the OpenTelemetry Transformation Language (OTTL). OTTL enables telemetry transformations based on any field of the payload, utilizing functions to execute the changes. In this session we’ll dive deeper into OTTL, how it solves problems, and how it sets users up for success. We will start with an overview of OTTL, then review common use cases, best practices, and common mistakes. Finally, we’ll look at what's coming up next for OTTL. By the end of this session, you'll know how to transform, filter, sample, and route data based on OTTL statements.
