rip, I would recommend you pay for Grafana Cloud and setup a bunch of data sources. Could also use axiom as your "data lake" if needed.

Also, looks like kamal already has some docs on how to scrape data: dev.37signals.com/kamal-prome…

The choice of tools above it's probably the cheapest money can buy for great quality (speaking from personal experience). I expect you will just need the $20 plan on Grafana.

I don't use Kamal, but happy to share my setup if it helps, as the data charts will also be applicable to you.
