Tracing HTTP methods with full payload

[francescom-zenity]

Hi,
First thanks for this great project. It's really nice to jump-start with eBPF using this tool!

Question: can I capture the full HTTP payload and export that into an OTEL Trace somehow?
E.g. I see ebpf-instrument printing in my test lab:

autoinstrumenter-1  | [
autoinstrumenter-1  |  {
autoinstrumenter-1  |   "type": "HTTPClient",
autoinstrumenter-1  |   "peer": "172.18.0.2",
autoinstrumenter-1  |   "peerPort": "36598",
autoinstrumenter-1  |   "host": "172.66.0.243",
autoinstrumenter-1  |   "hostPort": "443",
autoinstrumenter-1  |   "traceID": "7a1f65a0640e75d92b8c703d629b6469",
autoinstrumenter-1  |   "spanID": "3ea413975259ad7f",
autoinstrumenter-1  |   "parentSpanID": "0bf494805229b5c0",
autoinstrumenter-1  |   "traceFlags": "1",
autoinstrumenter-1  |   "peerName": "python3.11",
autoinstrumenter-1  |   "hostName": "api.openai.com",
autoinstrumenter-1  |   "kind": "SPAN_KIND_CLIENT",
autoinstrumenter-1  |   "start": "1770289742771539",
autoinstrumenter-1  |   "handlerStart": "1770289742771539",
autoinstrumenter-1  |   "end": "1770289744726826",
autoinstrumenter-1  |   "duration": "1.955287086s",
autoinstrumenter-1  |   "durationUSec": "1955287",
autoinstrumenter-1  |   "handlerDuration": "1.955287086s",
autoinstrumenter-1  |   "handlerDurationUSec": "1955287",
autoinstrumenter-1  |   "attributes": {
autoinstrumenter-1  |    "clientAddr": "python3.11",
autoinstrumenter-1  |    "method": "POST",
autoinstrumenter-1  |    "serverAddr": "api.openai.com",
autoinstrumenter-1  |    "serverPort": "443",
autoinstrumenter-1  |    "status": "200",
autoinstrumenter-1  |    "url": "/v1/completions"
autoinstrumenter-1  |   }
autoinstrumenter-1  |  },

but I couldn't find a way to get in "attributes" also the payload of the HTTP POST...

Hi, it's not an implemented feature as of now, there's a design proposal here #396 and it's in OBI's 2026 roadmap -> OBI Roadmap

Thanks @mmat11 for the fast answer. Looking forward for that feature then
