Monitoring

Stack

The monitoring stack runs on london-a — a FreeBSD machine dedicated to observability. The choice of FreeBSD here is deliberate: it's lightweight, stable, and well-suited for a machine whose job is to just sit there and watch things.

Prometheus — scrapes metrics from all servers and services
Grafana — dashboards and visualisation
node_exporter — system metrics on each Linux/FreeBSD server
smartctl_exporter — disk health metrics from london-b (Docker)
prom-plex-exporter — Plex session and library metrics from london-b (Docker)

What Gets Scraped

All servers in the homelab run node_exporter and are reachable by Prometheus via Tailscale. Prometheus scrapes each target over the Tailscale network, so nothing needs a public port.

Dashboards

Grafana is accessible via Cloudflare tunnel + Authelia for SSO. There's also a refurbished tablet mounted on the fridge in the living room showing a few key dashboards — a quick way to see if everything is healthy without opening a browser.

Alerting

Not yet configured. This is a gap worth filling.
