Ferrule

Ferrule is a monitoring dashboard for UniFi networks, hypervisors and storage. It shows what the vendors' own screens mostly don't: fan speeds, per-port error counters, SFP optics, PoE draw, temperatures, NVR disk health, WAN failover and cable modem health. It also keeps its own record of outages, so the record survives the controller.

This repository is how you deploy it: a Docker Compose stack, run from Portainer or from the command line. Ferrule runs from a published image, so nothing is built on your host.

Full documentation: https://docs.ferrulehq.dev

What you need

A Docker host with Portainer or Docker Compose, and outbound internet access to download the images.
At least one thing to watch:
- a UniFi console (gateway, and a UNVR for Protect);
- or Proxmox VE, Proxmox Backup Server, vCenter/ESXi;
- or a Synology, QNAP or TrueNAS.
A license key, if you're a beta tester; you'll get it from us. Without one, Ferrule starts a 30-day trial of the paid features. When the trial ends, it keeps monitoring, with the paid features paused.

Install

Create read-only accounts on what you'll watch, such as a UniFi API key and a local read-only admin. Each system's exact steps are under Connect your gear.
Get the stack:
- Portainer: Stacks → Add stack → name ferrule → Repository, with URL https://git.uglyhousesneedlove.com/steve/ferrule-deploy, reference refs/heads/main, compose path docker-compose.yml, and authentication off.
- Docker Compose:
```
git clone https://git.uglyhousesneedlove.com/steve/ferrule-deploy.git ferrule
cd ferrule
cp stack.env.example .env
```
Fill in the settings from stack.env.example: your hosts and credentials. Keep FERRULE_VERSION as it is: it's the current release. Set UNIFI_ENABLED=false if you have no UniFi console.
- Portainer: paste them under Environment variables (Advanced mode).
- Docker Compose: edit .env.
Start it: Deploy the stack in Portainer, or docker compose up -d. Then open http://<docker host>:8090.
Settings → License: paste your key and press Apply. It shows "Waiting for the first check-in" for up to about two hours, then "Confirmed online".

Once it's running, Settings → Stack environment writes the lines for everything else: hypervisors, storage, notifications and sign-in.

Updating

When a new release comes out, set FERRULE_VERSION to it, then click Pull and redeploy in Portainer, or run docker compose up -d. Nothing changes until you do.
