LibreNMS + Weathermap for graphs, real-time, and alerting. Vaping for a simple Up/Degraded/Down dashboard (great replacement for Multiping/PingPlotter on a TV). Elastiflow for netflow.

I really really want to like OpenNMS, and would love to use it daily; I feel like it could handle many integrations well, but have never had the time to dedicate to fully diving into it. I have used it in the past for small setups (monitoring ~100 remotely managed routers/firewall) and it did well, after getting past some learning curves. I keep coming back to it every 6 months or so and trying the latest version.

We are looking for a new network monitoring system. Since there are so many operators on this list, I would like to know which NMS do you use and why? Is there one that you really like, and others that you hate?

For free options (opensouce), LibreNMS and NetXMS come highly recommended by many wireless ISPs on low budgets. However, I am not sure the commercial options available nor their price points.
