unifi-poller VS snmp_exporter

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.

Unpoller to collect metrics from my network devices

It is kind of described here:https://github.com/prometheus/snmp_exporter/issues/405

The SNMP exporter can do lookups. Take a look at this documentation.

wget https://github.com/prometheus/snmp_exporter/releases/download/v0.21.0/snmp_exporter-0.21.0.linux-amd64.tar.gz

You need to find the OSBs for the router, and add those to the explorer. Take a look at this doc: https://github.com/prometheus/snmp_exporter/blob/main/generator/README.md

You can fetch this metrics using the SNMP exporter https://github.com/prometheus/snmp_exporter

As a maintainer of the Prometheus SNMP exporter, and the defacto standard implementation of SNMP in Go, I can tell you exactly how convoluted SNMP is at a protocol and specification level.

Refer to https://github.com/prometheus/snmp_exporter and https://blog.paessler.com/how-to-enable-snmp-on-your-operating-system

For example, you can use unpoller to bring your unifi stuff into the same system as your SNMP data.

SNMP by itself is a rather crude protocol, with values being identified as OID (Object IDs). Those are numerical identifiers. A MIB-File contains the information on how to translate these OIDs into workable data. There is some information on how to feed these files to the exporter located here: https://github.com/prometheus/snmp_exporter/tree/main/generator
