@stephenw10 said in Properly Prometheus (with alertmanager & exporters) + Grafana installation on CE DEV version:

Not on pfSense directly. 😉

Why? Exactly pfSense have exporter for Prometheus. So the question about version are still actual.

There are quite a few tutorials on how to do exactly this by exporting the data to another host. And that's the correct way to do it IMO.

Of course, I read it. But asking about tho new version are only on official Prometheus web, but quite old version are in FreeBSD repo.
