OTel Meets Wasm: Rethinking OpenTelemetry Collector Extensibility - Kotaro Inoue, Individual & Tsuzuki Tsuchiya, LY Corporation
OpenTelemetry Collector is a flexible, vendor-neutral telemetry pipeline, but extensibility is still more operationally expensive than it should be. The contrib distribution offers many community components, yet some teams cannot adopt the full binary as-is because they require tighter control over included functionality and security posture. Building a smaller collector with only the necessary components is possible, but in practice, it often means maintaining a custom build pipeline just to support relatively small extensions. This talk explores an alternative model for dynamically customizing the OpenTelemetry Collector with WebAssembly. Instead of rebuilding and redistributing the entire collector binary for each change, custom receiver, processor, and exporter logic can be introduced in a more decoupled way. The session examines what this model enables, where it fits, where it falls short, and what trade-offs emerge around safety, portability, performance, and operations.
