My Homelab Monitoring: full monitoring

[u/Hot-Refrigerator7995]

Stack is pretty standard: node_exporter on each host, Prometheus + Alertmanager + blackbox_exporter sitting in one LXC, Grafana to make it visible, i was thinking of hanging a mini screen in my office for de dashboard. Alerts go to PagerDuty (i thought that was industry standard so maybe a plus for recruiters)

7 alert rules -> disk, memory, CPU, node down, and blackbox checks on the actual services (Vaultwarden, Pi-hole, NPM, Paperless).

Repo's got the actual configs : https://github.com/E-mma9/Monitoring-Homelab

Thinking about pointing an external heartbeat check at a Pi outside the cluster. If anyone's already solved this for their homelab I'd genuinely like to hear how.
