ntopng-udm VS unifi-poller

My friend just did ntopng on his with this script.https://github.com/tusc/ntopng-udm

I read about https://github.com/tusc/ntopng-udm but needing to do that and having to have another webpage up to see the kind of information I want ( not even sure if this is "real-time" ) is not a great solution.

You can view the DPI stats in the controller which no one has ever trusted. You can also use some 3rd party tools like iftop of ntopng to track bandwidth use. Full disclosure, I ported ntopng to the UDM: https://github.com/tusc/ntopng-udm

If you want something much better, do yourself a favour and install ntopng on your UDM. It records much more information than DPI like time-series data, supports IPv6, and is much more accurate at classifying traffic. You can read all the features ntop supports here.

You should look into setting up Ntopng. Wayyyy better monitoring and can track individual usage by IP, devices, etc. You set it up directly on the UDM or UDMP so no additional hardware. I haven’t noticed any performance delays on it either. The link is below. Feel free to shoot me questions if you got any. https://github.com/tusc/ntopng-udm

possibly https://unpoller.com/ ?

I'm looking for something that will pull near real time switch port traffic. The 5 min avg that the gui gives you isn't granular enough. I did find https://unpoller.com/, but doesn't appear to be updated in a few years. Is there anything else, that maybe uses SNMP or something?

I have Unfi equipment and I use unpoller

Not at all. If you're looking to get accurate metrics from the Unifi, then I'd suggest using UniFi Poller with Grafana

If you've got Ubiquiti like I do you can use https://github.com/unpoller/unpoller to push your logs / stats to your stack I believe. Or alternatively the OPNsense one.

Unifi Poller -> Prometheus -> Grafana

The Dashboard consists of: Varken for aggregating data from the Plex ecosystem into InfluxDB using Grafana for a frontend. OPNsense capturing with the help of Telegraf plugin. Adguard Home monitoring utilizing a custom exporter named Adguard_Exporter for prometheus. UniFi agregating with UnPoller. For TrueNAS Scale, I installed the community catalog for installing Kube Apps, this allowed me to installed Prometheus and use the node-exporter provided on this dashboard. Proxmox metrics server provided here.

Why not just use https://github.com/unpoller/unpoller and modern observability like Prometheus and Loki for events and logs ?? It is working on my side and cannot back to things like Zabbix, Cacti or anything like this. Alerting also possible without any problems.
