LibreNMS is great. If you put in the work, it can be wonderful. Those who were around at the time remember just how bad other systems were, then Observium’s founder crashed out and LibreNMS, Observium’s fork, really shined.

Any SMB would get amazing value out of LibreNMS to this day. Sadly, it’s not really keeping pace with things like event driven architecture nor streaming telemetry. But building a modern LibreNMS in the aggregate with Streaming telemetry, grafana, prometheus, NATS, suzie-q, etc. is way harder than it seems. LibreNMS & it’s intuitive UI & SNMP walking still makes me smile.
