Pulse for Proxmox

Real-time monitoring for Proxmox VE and PBS with alerts and webhooks.

💖 Support This Project

Features

• Auto-Discovery: Finds Proxmox nodes on your network, one-liner setup via generated scripts
• Cluster Support: Configure one node, monitor entire cluster
• Security: Credentials encrypted at rest, masked in logs, never sent to frontend
• Live monitoring of VMs, containers, nodes, storage
• Alerts with email and webhooks (Discord, Slack, Telegram, Teams, ntfy.sh, Gotify)
• Unified view of PBS backups, PVE backups, and snapshots
• PBS push mode for firewalled servers
• Config export/import with encryption and authentication
• Dark/light themes, responsive design
• Built with Go for minimal resource usage

Quick Start

Install

# Option A: Proxmox Helper Script (creates LXC container)
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/pulse.sh)"

# Option B: Docker
docker run -d -p 7655:7655 -v pulse_data:/data rcourtman/pulse:latest

# Option C: Manual (existing systems)
curl -fsSL https://raw.githubusercontent.com/rcourtman/Pulse/main/install.sh | sudo bash

Configure Nodes

1. Open http://<your-server>:7655
2. Go to Settings → Nodes
3. Discovered nodes appear automatically
4. Click "Setup Script" next to any node
5. Run the generated one-liner on that node
6. Node is configured and monitoring starts

The script handles user creation, permissions, token generation, and registration automatically.

Docker

Basic

docker run -d \
  --name pulse \
  -p 7655:7655 \
  -v pulse_data:/data \
  --restart unless-stopped \
  rcourtman/pulse:latest

With Network Discovery

# Specify your LAN subnet for auto-discovery
docker run -d \
  --name pulse \
  -p 7655:7655 \
  -v pulse_data:/data \
  -e DISCOVERY_SUBNET=192.168.1.0/24 \
  --restart unless-stopped \
  rcourtman/pulse:latest

PBS Agent (Push Mode)

For isolated PBS servers, see PBS Agent documentation

Security

• Credentials encrypted at rest (AES-256-GCM)
• Tokens masked in logs
• Frontend never receives actual credentials
• Export requires authentication

See Security Documentation for details.

Configuration

Quick start - most settings are in the web UI:

• Settings → Nodes: Add/remove Proxmox instances
• Settings → System: Polling intervals, CORS settings
• Alerts: Thresholds and notifications

For deployment overrides (ports, etc), use environment variables:

# Systemd: sudo systemctl edit pulse-backend
Environment="FRONTEND_PORT=8080"

# Docker: -e FRONTEND_PORT=8080

📖 Full Configuration Guide →

Backup/Restore

# Export (v4.0.3+)
pulse config export -o backup.enc

# Import
pulse config import -i backup.enc

Or use Settings → Security tab in UI.

Updates

Docker

docker pull rcourtman/pulse:latest
docker stop pulse
docker rm pulse
# Run docker run command again

Manual Install

Settings → System → Check for Updates

After updates complete, refresh your browser (Ctrl+F5 or Cmd+Shift+R) to load the new version.

API

# Status
curl http://localhost:7655/api/status

# Metrics
curl http://localhost:7655/api/metrics

# With authentication (if configured)
curl -H "X-API-Token: your-token" http://localhost:7655/api/status

Reverse Proxy

Using Pulse behind a reverse proxy? WebSocket support is required for real-time updates.

See Reverse Proxy Configuration Guide for nginx, Caddy, Apache, Traefik, HAProxy, and Cloudflare Tunnel configurations.

Troubleshooting

Connection Issues

• Check Proxmox API is accessible (port 8006/8007)
• Verify credentials have PVEAuditor role minimum
• For PBS: ensure API token has Datastore.Audit permission

High CPU/Memory

• Reduce polling interval in Settings
• Check number of monitored nodes
• Disable unused features (backups, snapshots)

Logs

# Docker
docker logs pulse

# Manual
journalctl -u pulse -f

Security

• Credentials stored encrypted (AES-256-GCM)
• Optional API token authentication
• Export/import requires passphrase
