Pulse - Proxmox Monitoring System

Pulse is a real-time monitoring system for Proxmox Virtual Environment (PVE) and Proxmox Backup Server (PBS) with a modern web interface.

Features

• 📊 Real-time Monitoring - Live updates of VMs, containers, nodes, and storage
• 💾 Unified Backup View - See PVE backups, PBS backups, and snapshots in one place
• 🚨 Smart Alerts - Configurable thresholds with webhook notifications
• 📈 Performance Metrics - Historical data with interactive charts
• ⚙️ Flexible Configuration - Configure via UI, config files, environment variables, or CLI
• 🌐 Multi-Instance Support - Monitor multiple PVE clusters and PBS instances

Quick Start

Using Docker (Recommended)

docker run -d \
  -p 3000:3000 \
  -p 7655:7655 \
  -v /path/to/config:/etc/pulse \
  -e PULSE_SERVER_BACKEND_PORT=3000 \
  -e PULSE_SERVER_FRONTEND_PORT=7655 \
  --name pulse \
  pulse:latest

Manual Installation

1. Clone the repository:

git clone https://github.com/yourusername/pulse.git
cd pulse

2. Build the backend:

go build -o bin/pulse ./cmd/pulse

3. Install frontend dependencies:

cd frontend-modern
npm install
npm run build
cd ..

4. Create configuration:

./bin/pulse config init
# Edit pulse.yml with your Proxmox credentials

5. Run Pulse:

./bin/pulse

Access the web interface at http://localhost:7655

Configuration

Pulse supports multiple configuration methods with the following precedence (highest to lowest):

1. Command-line arguments
2. Environment variables
3. Configuration file (pulse.yml)
4. Default values

Configuration Methods

1. Web UI Configuration

Navigate to the Settings tab in the web interface to configure ports, monitoring intervals, and other settings.

2. Configuration File

Generate an example configuration:

./bin/pulse config init

Example pulse.yml:

server:
  backend:
    port: 3000
    host: "0.0.0.0"
  frontend:
    port: 7655
    host: "0.0.0.0"

monitoring:
  pollingInterval: 5000      # milliseconds
  backupPollingCycles: 10    # poll backups every N cycles

3. Environment Variables

export PULSE_SERVER_BACKEND_PORT=8080
export PULSE_SERVER_FRONTEND_PORT=8081
export PULSE_LOG_LEVEL=debug

4. Command-Line Arguments

./bin/pulse --backend-port=8080 --frontend-port=8081 --log-level=debug

Proxmox Configuration

Create /etc/pulse/nodes.json:

{
  "pve_instances": [
    {
      "name": "my-cluster",
      "host": "https://proxmox.example.com:8006",
      "username": "monitor@pve",
      "token_name": "monitor-token",
      "token_value": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "verify_ssl": false
    }
  ],
  "pbs_instances": [
    {
      "name": "my-backup-server",
      "host": "https://pbs.example.com:8007",
      "username": "monitor@pbs",
      "token_name": "monitor-token",
      "token_value": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "verify_ssl": false
    }
  ]
}
