🖥️ Vitals: A JavaFX-Based System Monitor Dashboard Built for Power Users

By Ankesh Kumar

🚀 Introduction

As developers and power users, we often rely on built-in or third-party system monitoring tools. However, many of them either feel too bloated or too bare-bones. That’s what inspired me to build Vitals — a sleek, cross-platform system monitoring desktop app developed in JavaFX that blends performance insights with a clean, modern UI and exportable reports.

Vitals isn’t just about numbers — it’s about understanding your machine’s behavior in real time and historically.

🧠 Why I Built Vitals

Vitals UI

Like many, I was frustrated with inconsistent and non-customizable monitoring utilities. Task Manager shows data but lacks long-term logging. Other tools are good but heavy or not visually appealing.

So, I decided to create an app that:

• Monitors CPU, Memory, Disk, and Network usage.
• Maintains historical logs using SQLite.
• Allows PDF/CSV export for reporting and diagnostics.
• Looks modern, dark-themed, and intuitive.

🖼️ A Quick Look

Vitals Dashboard Highlights:

• Real-time charts with smooth graph updates
• Export button integrated into the UI
• Panels for all major system components
• Historical metrics filtering by hour, day, and week

🔧 Tech Stack Breakdown

Vitals leverages the power of:

• Java 24: The latest JVM features
• JavaFX 21: For building elegant and responsive desktop UIs
• OSHI: A robust library for hardware/system-level metrics
• SQLite: Efficient logging for historical data
• Apache PDFBox: For structured PDF report generation
• Maven: Dependency and build management

⚙️ Key Features

📊 Real-Time Monitoring

Vitals actively displays:

• CPU usage, clock speed, and process count
• Memory metrics: used, available, and total
• Disk utilization in GB and %
• Network speeds: download/upload

🕒 Historical Logging

Every monitored metric is periodically saved:

• Lightweight SQLite storage
• Smart in-memory aggregation for visual readability
• Time-range filtering UI (last hour, day, week)

📝 Export Options

Export your system state:

• PDF reports for IT documentation and reports
• CSV files for detailed analytics and debugging

🖱️ Installation & Usage

Vitals comes with a native Windows MSI installer, making setup seamless. Once installed:

1. Launch the app
2. Navigate between Dashboard and Historical View
3. Export snapshots with one click

✅ JDK 24, JavaFX 21 SDK, and Maven 3.6+ are required for building from source.
