summary
Claim: a small open source Observe toolkit lets the host extract traces, metrics and logs from guest WebAssembly modules and forward them to existing backends. It demonstrates a Rust axum + Wasmtime iota FaaS that instruments calls with an instrument macro, exports spans/logs/metrics via adapters to DataDog/Honeycomb and to OpenTelemetry formats, and supports Rust, C/C++, Go and JS runtimes. An auto‑instrumentation compiler and runtime shims are implemented and the demos already work end‑to‑end.
