Wasm I/O 2025 - Barcelona, 27-28 March Slides: https://2025.wasm.io/slides/unlocking-observability-in-webassembly-with-opentelemetry-wasmio25.pdf WebAssembly (Wasm) is transforming the cloud-native landscape with its unmatched security, performance, and portability. As Wasm continues to evolve, ensuring it is observable becomes essential. Join us for an update on how OpenTelemetry integrates with WebAssembly. We’ll explore the latest advancements in extracting traces, metrics, and logs from Wasm components, guided by open-source standards like WASI OTel. Additionally, we’ll highlight the unique advantages Wasm offers to observability, such as automatic cross-language instrumentation. The session will conclude with live demos showcasing WebAssembly observability in production.
