glancewatch 1.0.4

Lightweight monitoring adapter bridging Glances metrics with Uptime Kuma

GlanceWatch 🎯

GlanceWatch is a lightweight monitoring adapter that bridges Glances system metrics with Uptime Kuma and other monitoring tools. It exposes simple HTTP endpoints with configurable thresholds that answer: "Is my system healthy?"

✨ Features

• 🚀 One-Command Install: pip install glancewatch - everything included
• 🔄 Auto-Glances Management: Automatically installs and starts Glances for you
• 🎯 HTTP Status Alerting: Returns HTTP 200 (OK) or 503 (unhealthy) based on thresholds
• 🎨 Router-Style Web UI: Clean admin interface at / (root)
• ⚙️ Configurable Thresholds: Set custom limits for RAM, CPU, and disk usage
• 💾 Persistent Configuration: Changes saved to config.yaml automatically
• 📊 Multiple Disk Monitoring: Monitor all or specific mount points
• 🏥 Health Checks: Built-in health endpoint for service monitoring
• 📝 OpenAPI Docs: Auto-generated API documentation at /api
• 📈 Real-Time Metrics: Auto-refreshing dashboard shows live system status

🚀 Quick Start

# Install GlanceWatch (automatically installs Glances dependency)
pip install glancewatch

# Run GlanceWatch (auto-starts Glances if needed)
glancewatch

# Access the web UI
open http://localhost:8000

That's it! 🎉 GlanceWatch automatically handles Glances installation and startup.

🎯 Usage

# Start GlanceWatch (auto-starts Glances)
glancewatch

# Start without auto-starting Glances
glancewatch --ignore-glances

# Custom port
glancewatch --port 9000

# Custom host
glancewatch --host 0.0.0.0

📡 API Endpoints

• GET / - Web UI (root endpoint)
• GET /status - Combined status (HTTP 503 on threshold violation)
• GET /ram - RAM usage check
• GET /cpu - CPU usage check
• GET /disk - Disk usage check
• GET /health - Service health check
• GET /config - Get configuration
• PUT /config - Update thresholds
• GET /api - Interactive API documentation

🔔 Uptime Kuma Integration

1. In Uptime Kuma, create a new HTTP(s) monitor
2. Set URL to: http://your-server:8000/status
3. Set "Accepted Status Codes" to: 200

When any metric exceeds its threshold, GlanceWatch returns HTTP 503, triggering an alert.

⚙️ Configuration

GlanceWatch creates ~/.config/glancewatch/config.yaml:

glances_base_url: "http://localhost:61208/api/4"
host: "0.0.0.0"
port: 8000
log_level: "INFO"
return_http_on_failure: 503

thresholds:
  ram_percent: 80
  cpu_percent: 80
  disk_percent: 85

disk:
  mounts:
    - "/"

Adjust thresholds via the Web UI at / or edit the config file.
