This person gives a good run down of how to integrate NetData + Prometheus + Grafana to create a nice dashboard:

I am not much into those, but got into Netdata, it's really just a nice information portal which provides way more data than one can use, but they pretty much expose it so you can use it for your purposes. I have it on a few of my systems and like looking at it when they seem slow.

For what I have for my end though - I use Proxmox for my VM's and then use Portainer for a good rundown of what ports I have available to allocate. But then I also use docker compose files whenever I can so it's easier to update/deploy as needed.
