I want something that has a WebUI, can show in a graph like the CPU and RAM graph for this day and maybe some days before. Also I would like to view what was running at any given time (I mean from 2-3 days before to now).
Is there any (FOSS) software that does that?
Thanks.
I think prometheus + grafana might be what you are looking for. In combination with loki grafana can also be used for viewing log messages.
Absolutely this, nothing else is required. Well, maybe alertmanager if you want to receive alerts
and swap Prometheus for VictoriaMertics, or your homelab ram usage becomes Prometheus ram usage.
I’ll second this. Prometheus + Grafana is what I’m using now, but you can definitely add more extensions/monitors to get far more detail, like Loki which was suggested above.
Do both have to run on the host machine or can a remote machine execute the probes (over ssh or something).

Grafana is just the frontend, its a dashboard for your different data sources Prometheus is the “database”, it scrapes data from your endpoints over http
