glancewatch 1.2.4

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

Installation

macOS (Homebrew)

brew tap collynes/glancewatch
brew install glancewatch
glancewatch

Windows (Chocolatey)

choco install glancewatch
glancewatch

Node.js/npm (All platforms)

# Global installation

Quick Start

Background Service (Recommended for Production)

Linux/Ubuntu (systemd):

# One-command install as background service
curl -sSL https://raw.githubusercontent.com/collynes/glancewatch/main/scripts/install-pip.sh | bash

# Service automatically starts on boot and runs in background

Simple background start (nohup):

# Start in background
nohup glancewatch > /dev/null 2>&1 &

# Check if running
ps aux | grep glancewatch

See docs/BACKGROUND-SERVICE.md for complete guide including screen/tmux options.

Foreground (Development)

pip install glancewatch
glancewatch

# Or run with custom port
glancewatch --port 8080

# Access the dashboard
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 /docs - 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.
