# london-a
|
|
|
|
Dedicated monitoring server. Runs Prometheus and Grafana, nothing else.
|
|
|
|
## Overview
|
|
|
|
| | |
|
|
|---|---|
|
|
| **Location** | London (NW9) |
|
|
| **OS** | FreeBSD 14.3 |
|
|
| **Tailscale IP** | 100.122.219.41 |
|
|
| **Role** | Monitoring (Prometheus + Grafana) |
|
|
|
|
## Hardware
|
|
|
|
| Component | Spec |
|
|
|---|---|
|
|
| CPU | Intel i7-4790K (8 threads) |
|
|
| Memory | 32 GB |
|
|
| Boot disk | 1 TB |
|
|
|
|
Old gaming PC, now perfectly happy as a monitoring host. Very lightly loaded — disk at ~6%.
|
|
|
|
## Services
|
|
|
|
| Service | Port | URL |
|
|
|---------|------|-----|
|
|
| Prometheus | 9090 | prometheus.pez.sh |
|
|
| Grafana | 3000 | grafana.pez.sh |
|
|
|
|
Both are behind Authelia (auth handled by Caddy on helsinki-a).
|
|
|
|
## Why FreeBSD
|
|
|
|
This one runs FreeBSD instead of Ubuntu. For a single-purpose monitoring host it works well. No particular reason to change it — it's stable and does its job.
|
|
|
|
## Networking
|
|
|
|
Connected via Cat 5 to the Ubiquiti switch alongside london-b.
|
|
|
|
## Notes
|
|
|
|
Prometheus scrapes all hosts over Tailscale. See [monitoring.md](../monitoring.md) for scrape targets and dashboard details.
