Topology: a live page drawn from the real gear

Browse Source

The dashboard's hand-drawn diagram was out of date. /topology replaces it
with the network as the switches report it, every device drawn to scale
from its faceplate or cutsheet front, and one cable per physical link
leaving the port it is plugged into.

- topology.py builds the graph: switch-to-switch cables seen from both ends
  are merged, servers get one cable per NIC, the gateway's internet port
  goes to the modem and on to the internet, unknown neighbours are stubs,
  and gear with no live cable is drawn where it was last seen.
- Ports named after a different device than the one plugged in are flagged.
- Cables show medium, speed, state and traffic; click one for its details,
  hover a device to trace its path to the internet; pan, zoom and filters.
- The monitor now keeps host_macs (MAC to host NIC) in link_stats.
- The old dashboard diagram and its JS and CSS are removed.
