This is the live component responsible for the Network pillar: the busiest inet ports on a selected node, ranked by received/sent bytes per refresh interval (deltas between samples, cumulative on the first tick), plus the NIF-based socket module sockets that port listings miss. A drill-down panel shows the selected port's full inet options.

Refresh ticks carry a generation counter: changing any control bumps the generation and starts a new timer chain, so a tick from a cancelled chain that was already in flight is ignored instead of spawning a second chain.
