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 use this too. When SNMP is set up there are loads of things you can monitor with LibreNMS. Much less of a learning curve than Grafana + Prometheus, although the latter probably has some nice tweaks available that SNMP does not provide.
