Window Service Watcher

A lightweight, modern desktop application for real-time monitoring and management of Windows services.

---

✨ Overview

Provide a seamless dashboard for developers and system admins to monitor status, track resources (CPU/RAM), and control critical services. Default configuration supports monitoring POS services, but can be adapted for any Windows service.

Key Features

Feature	Description
⚡ Real-time Monitoring	Live status updates (Running, Stopped, Paused) with sub-second latency.
📊 Resource Tracking	Visual graphs for CPU usage (%) and Memory consumption (MB).
🎮 Service Control	Start, Stop, and Restart services directly from the UI.
📦 Smart Installation	Install and update service executables/files with one click.
⚙️ Configurable	Simple YAML configuration for managing multiple services.
🔔 System Tray	(Coming Soon) Background operation and status notifications.

🏗️ Architecture

Built on the Clean Architecture principle, ensuring separation of concerns and maintainability.

• Frontend: Svelte 5 + TailwindCSS for a high-performance, reactive UI.
• Backend: Go + Wails for native Windows API interaction.
• Bridge: Async communication via Wails runtime events (services-update).

🚀 Usage Guide

Configuration (config.yaml)

The app auto-generates this file on first run.

services:
  - id: "550e8400-e29b-41d4-a716-446655440000" # Unique ID
    name: "Payment Gateway Service"           # Display Name
    serviceName: "PaymentSvc"                 # Actual Windows Service Name
    path: "C:\\Services\\Payment\\app.exe"    # Executable Path
    installable: true                         # Allow file updates

Dashboard Controls

• Status Cards: (🟢 Running, 🔴 Stopped, 🟡 Pending).
• Play/Stop: Toggle service state.
• Metrics: Hover over cards to see detailed CPU/RAM history.

🐞 Troubleshooting

❌ Service Not Found / Error Fetching State

• Cause: serviceName in config.yaml doesn't match the actual Windows Service name.
• Fix: Check services.msc for the exact Service Name (not Display Name) and update config.

🚫 Permission Denied

• Cause: Controlling Windows services requires Administrator privileges.
• Fix: Run the application or terminal as Administrator.

📉 Metrics Not Showing

• Cause: The service might be running but the process ID (PID) cannot be retrieved, or monitoring is blocked.
• Fix: Ensure the service is actually running and you have permissions to query its process information.
