# Proxmox Monitor

A real-time dashboard for monitoring Proxmox VE nodes, VMs, and LXC containers.

## Features

- **Node overview** — CPU, memory, uptime, and load for each Proxmox node, grouped into collapsible cards
- **VM & LXC tracking** — status, resource usage across all nodes
- **Summary cards** — total nodes, running/stopped VMs, aggregate memory
- **Per-VM/LXC IP addresses** — IPv4 from guest agent (QEMU) or network config (LXC), displayed below VM/LXC name
- **Power control** — Start/stop/restart buttons per row
- **Console links** — Opens Proxmox web UI console in a new tab
- **Search / filter** — Client-side filtering by name, node, or status with auto-expand
- **Group by node** — Collapsible node cards with running/stopped subtotals
- **Manual refresh** — Button in header to refresh all data
- **Custom poll interval** — Adjustable polling interval (default 30s) via header input
- **Uptime display** — Formatted as "Xd Yh Zm"
- **Auto-refresh** — Manual `setInterval` polling every 30s (configurable)

## Tech Stack

- **Framework** — Next.js 15 (App Router)
- **UI** — React 19, Tailwind CSS 4
- **Data fetching** — Axios with manual `setInterval` polling
- **Proxmox** — API2 Token-based auth

## Getting Started

### 1. Configure environment variables

Copy the example file and fill in your Proxmox credentials:

```bash
cp .env.example .env.local
```

`.env.local` contents:

```
PROXMOX_API_URL=https://your-proxmox-host:8006/api2/json
PROXMOX_TOKEN_ID=root@pam!token-name
PROXMOX_TOKEN_SECRET=<your-token-secret>
API_POLL_INTERVAL=30000
NODE_TLS_REJECT_UNAUTHORIZED=0
```

> **Creating an API token** in Proxmox: Datacenter > Permissions > API Tokens

### 2. Install dependencies

```bash
npm install
```

### 3. Run the development server

```bash
npm run dev
```

Open [http://localhost:3000](http://localhost:3000) in your browser.

### 4. Build for production

```bash
npm run build
npm start
```

## Environment Variables

| Variable | Required | Description |
|---|---|---|
| `PROXMOX_API_URL` | Yes | Base URL of the Proxmox API (e.g. `https://host:8006/api2/json`) |
| `PROXMOX_TOKEN_ID` | Yes | API token ID (e.g. `root@pam!monitorapp`) |
| `PROXMOX_TOKEN_SECRET` | Yes | API token secret |
| `PROXMOX_WEB_URL` | No | Web UI URL (defaults from `PROXMOX_API_URL`). Used for console links. |
| `API_POLL_INTERVAL` | No | Refresh interval in ms (default: `30000`) |
| `NODE_TLS_REJECT_UNAUTHORIZED` | No | Set to `0` for self-signed certs |

## API Routes

| Route | Method | Description |
|---|---|---|
| `/api/nodes` | GET | All Proxmox nodes |
| `/api/vms` | GET | All QEMU VMs (with IPv4 from guest agent) |
| `/api/lxc` | GET | All LXC containers (with IPv4 from interfaces/config) |
| `/api/status` | GET | Aggregated summary stats |
| `/api/power` | POST | Power control (start/stop/restart) |
| `/api/proxy/*` | GET | Reverse proxy to Proxmox web UI |

## Per-VM/LXC IP Addresses

- **QEMU VMs**: fetched from `/nodes/<node>/qemu/<id>/agent/network-get-interfaces` (requires QEMU guest agent installed)
- **LXC**: fetched from `/nodes/<node>/lxc/<id>/interfaces` (preferred) or parsed from `/config` `net0`-`net7` fields (fallback)
- IPv4 only — IPv6 addresses are excluded
