Zero-code observability: OpenTelemetry meets eBPF with OBI

OpenTelemetry has more or less won the observability standard war, and for good reason — vendor-neutral traces, metrics and logs, one wire format (OTLP), one collector to ship it all wherever you want. The catch is the part nobody enjoys: actually instrumenting the code. SDKs mean touching every service, in every language, and redeploying. For a greenfield Go service that’s fine. For forty mixed-language services — half of which nobody wants to redeploy — it’s a project.
