CERNE Network Discovery vs Netdisco

CERNE Network Discovery has no write-up on Specifiction yet; its figures are above.

Netdisco is free, self-hosted network management software for administrators of small through very large networks. It gathers IP and MAC address data into PostgreSQL through SNMP, command-line interfaces, or device APIs. A lookup by MAC address or IP can show the connected switch port, which administrators can disable or change for VLAN or PoE status. Netdisco inventories hardware by model, vendor, software, and operating system, and preserves historical system IP and location data. It can draw network diagrams and expose search and retrieval through an API. The distribution includes a web interface, backend daemon, and command-line interface; the maker says it runs on Linux or Unix and provides Docker images. Installation requires Perl 5.10 or later and PostgreSQL 9.6 or later. The first setup requires manually discovering a network device that knows its neighbors. Plugins can add interface or backend commands and actions.
