Lightning Talk: 5G CNFs Observability Based on eBPF

summary
An eBPF-based observability framework runs on Kubernetes with a controller + per-node daemonset that attaches eBPF programs to node network interfaces via BCC and Python, parses HTTP2, NGAP, PFCP and GTPU, and exposes labeled metrics to Prometheus/Grafana. Lab tests use free5GC and open5GS with UERANSIM to generate traffic and validate counters for requests, responses and response time, PFCP message types and codes, and GTPU bytes and forwarding time. Implementation works functionally; scaling to many UEs and handling TLS remains to be validated.
