What is pktz?

pktz is a Go-built, eBPF-powered network traffic monitor that delivers live, per-process and per-connection stats on your machine's network activity. Run `sudo pktz` for a terminal UI showing RX/TX rates, totals, open connections, and 5-minute graphs—no polling or sampling, just kernel-precise byte and packet counts. Filter by app or PID, toggle DNS resolution or GeoIP flags, and drill into details like RTT or retransmits.

Why is it gaining traction?

It combines eBPF accuracy with a polished TUI that feels like `htop` meets `tcpdump`: sortable process lists, connection views, Unicode graphs, and mouse support out of the box. Extras like Prometheus metrics (`pktz --metrics :9090`), JSON logging for pipes to jq, and a demo mode for safe screenshots set it apart from ss or nethogs. Container detection adds names to PIDs automatically.

Who should use this?

Sysadmins hunting bandwidth hogs on busy servers, backend devs tracing per-process leaks during load tests, or security teams spotting rogue connections in Kubernetes clusters. Ideal for anyone needing real-time network visibility without Grafana dashboards.

Verdict

Worth `go install`ing for instant live monitoring—prebuilt binaries and cap-based sudo avoidance make it dead simple. At 47 stars and 1.0% credibility, it's raw but battle-ready with great docs; test it now before it hits 1k.
