  • Top 3 processes by CPU usage

• Storage Statistics

  • Root partition details
  • Total, used, and free space
  • Usage percentage

• Network Statistics

  • IP address
  • MAC address
  • Network traffic (Received/Transmitted)
  • Real-time traffic monitoring

• Battery Information (if available)

  • Battery level percentage
  • Charging status

• User Interface Features

  • Configurable refresh rate (1s, 2s, 5s)
  • Clean and organized layout
  • Real-time updates

Requirements

• Linux operating system
• JDK 21 or higher
• GCC compiler
• Make utility

Building and Running

1. Clone the repository:

   git clone <repository-url>
   cd SystemDashboard

2. Build the native library:

   cd src/systemdashboard
   make clean
   make
   cd ..

3. Compile Java code:

   javac systemdashboard/SystemMonitor.java

4. Run the application:

   java -Djava.library.path=systemdashboard systemdashboard.SystemMonitor

Implementation Details

• Frontend: Java AWT/Swing for the graphical interface
• Backend: Native C code via JNI for system metrics
• Metrics Collection: Direct system calls and proc filesystem access
• Update Mechanism: Background thread with configurable refresh rate

Features in Detail

System Metrics

• CPU usage calculated from /proc/stat
• Memory information from sysinfo
• Disk statistics via statvfs
• Network traffic from /proc/net/dev
• Process information from /proc filesystem
• Battery status from /sys/class/power_supply

User Interface

• Organized panel layout
• Responsive design
• Theme support with proper contrast
• Interactive controls
• Real-time updates

Notes

• The application requires root partition access for disk statistics
• Network statistics exclude loopback interface
• Battery information is only available on systems with battery
• Process CPU usage is calculated based on process time
