Network Topology for Zabbix is now open source — public beta

Network Topology for Zabbix is now open source — a public beta under AGPL-3.0.

If you run Zabbix, you know the feeling: you can see that a host is red — but not what depends on it. That’s exactly what this frontend module is built for. It draws your infrastructure as an interactive map, and you don’t maintain the links by hand — they come from the LLDP/CDP neighbour tables your switches already report.

Port-to-port weathermap

Every link shows both ports and is coloured by the actually measured utilisation of that interface — not an estimate derived from host totals.

“Can I reboot this switch?”

Right-click a device, simulate the failure, and the map shows which hosts would lose connectivity. Before the maintenance window, not after.

Item pivot

Every filesystem, interface or disk across a host group in one table, with heatmap and percentiles — the view you’d otherwise assemble by clicking through Zabbix.

Where does it run?

Zabbix 7.0 LTS and 7.4, AGPL-3.0, no build tools required. Install in about two minutes — the steps are in the docs.

Why beta?

The core features are proven in production, but “public beta” means: LLDP in particular is done slightly differently by every switch vendor. I’d love feedback from the field — especially from people with mixed switch estates.

Code on GitHub; questions and feedback welcome by email or issue.
