My current home metrics + visualization stack is self-hosted Grafana OSS atop a Prometheus time series database. Prometheus is fed by mqtt2prometheus, which reads Mosquitto-brokered metrics from my bespoke scripts and various IoT devices. It also ingests SNMP via its own snmp_exporter. I was originally using Prometheus's node_exporter, but thought it horribly heavyweight.

Prometheus
By default, your databases will be in /var/lib/prometheus. The initial retention size and time, at least on Debian, are ridiculously small. Edit /etc/default/prometheus and add something like --storage.tsdb.retention.size=10GB --storage.tsdb.retention.time=10y to ARGS.
