# 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.
