Tracing

Tracing follows a request across services so you can see where time goes and where it fails. Useful from UI calls down to platform and network layers.

Cilium and eBPF

Cilium uses eBPF for networking, security, and visibility in Kubernetes. It can show service flows and policy behavior, and pairs with Prometheus and Grafana for dashboards. Layer 7 visibility (HTTP/gRPC) helps when microservices talk a lot and traditional network tools fall short.
