I have a homelab of raspberry pis, so I've long looked for a "low memory" monitoring solution. As far as I've found out, such a thing doesn't exist. ๐
People making/designing monitoring solutions are usually the same people who monitor big professional clusters, where "low memory" is a distant memory of something they had to deal with 20 years ago ๐
I've ended up using Grafana Cloud free tier (
https://grafana.com/pricing/) to move a big part of the monitoring stack out of the cluster, that helped a lot. ๐
