Per-pod Kubernetes network cost, by AWS billing path.

Tollwing is an open-source eBPF agent that attributes every byte of Kubernetes traffic to the exact pod, the conversation, and the AWS billing path paying for it: live, in dollars, across all 9 paths. It gets cross-AZ right where post-DNAT tools miss it. No app changes. ~0.1 to 0.5% CPU.

git clone https://github.com/tollwing/tollwing && cd tollwing && make demo

It prices a real cross-AZ scenario through the production cost engine in pure Go: no cluster, no kernel, no AWS account. Every number is oracle-tested.

_{Open-core: the full attribution engine is free and Apache-2.0. Tollwing Enterprise (early access), the self-hosted license-gated tier, adds CUR reconciliation, multi-cluster history, anomaly detection, and auto-remediation.}
