I need a lightweight yet robust Network Management System built with the same ease-of-use and depth of insight I enjoy in LibreNMS. The single purpose is clear: keep constant watch over my routers, switches, servers, workstations, and security appliances, then present that data in a way that lets me act before users feel any impact. Core expectations • Native SNMP discovery and polling that works out of the box, no manual OIDs unless I choose to add them. • Real-time performance views—interface throughput, CPU, memory, latency—rendered in responsive graphs that update without page refresh. • A flexible dashboard designer so I can drag-and-drop widgets and schedule custom PDF or CSV reports. • Alerting engine with rule builder and multi-channel notifications (e-mail is a must; Slack or webhook support is a plus). Your deliverable is a web-based application (Docker-ready if possible) fully installed on my test VM, documented well enough that I can add devices, set thresholds, and start receiving alerts on day one.
