unifi-poller VS blackbox_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.

So you need 2 modules, one for each ip version. As for autamating setting these up, we deploy our Prometheus server with salt so we can use Jinja templating in all our Prometheus config files. That really cuts down on repeating boiler plate code.

This is also interesting for other reasons; in host downtime situations you can sometime see they will drop one type of traffic and not the other.

A Pi is more than enough to run a full monitoring stack. Why reinvent the wheel?

You can also use the blackbox_exporter to probe various endpoints. But in reality, you don't need to do this most of the time since the up metric gets you what you want.

Synthetic Monitoring is the Grafana Cloud implementation. It uses the blackbox_exporter

Prometheus blackbox_exporter. Free and open source.

Check something called blackboxexporter https://github.com/prometheus/blackbox_exporter

I have seen some people doing with these traditional relational databases, and I was wondering if it could be a good fit for prometheus+grafana as I have been messing around with prometheus BlackBox exporter (https://github.com/prometheus/blackbox_exporter) for web status monitoring.

You should look into the projects https://github.com/prometheus/node_exporter and https://github.com/prometheus/blackbox_exporter

You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).
