This repository contains two system tray applications written in Go:

• CPU Monitor: Displays CPU usage per core and updates a bar chart icon in the system tray.

  CPU monitor systray icon with CPU usage:

  

  CPU monitor systray icon with menu:

• Memory Monitor: Displays memory usage statistics and updates a pie chart icon in the system tray.

  Mem monitor systray icon with Mem usage:

  

  Mem monitor systray icon with details menu:

  

Before compiling and running the applications, install the required dependencies:

# Install Go modules
go mod tidy

To build and run the applications on macOS:

# Build CPU Monitor
go build -o cpu-monitor ./cmd/cpu-monitor
./cpu-monitor

# Build Memory Monitor
go build -o mem-monitor ./cmd/mem-monitor
./mem-monitor

To build and run the applications on Windows:

# Build CPU Monitor
go build -ldflags "-s -w -H windowsgui" -o cpu-monitor.exe ./cmd/cpu-monitor
cpu-monitor.exe

# Build Memory Monitor
go build -ldflags "-s -w -H windowsgui" -o mem-monitor.exe ./cmd/mem-monitor
mem-monitor.exe

The following Go modules are used:

• github.com/Kodeworks/golang-image-ico: ICO image encoding for system tray icons.
• github.com/getlantern/systray: System tray interface for cross-platform support.
• github.com/shirou/gopsutil: Fetch system statistics such as CPU and memory usage.

• Displays live CPU core usage in the system tray.
• Displays memory usage statistics in the system tray.
• Updates system tray icons dynamically to reflect real-time usage.
• Provides an exit option to close the application.
