CoreMon is a lightweight system monitoring application designed for Zorin OS and other Ubuntu-based distributions. It provides real-time monitoring of CPU temperature and load, with a clean GTK-based interface.

System tray:

Features

Core Monitoring

• Real-time CPU Temperature Monitoring: Monitor temperature for individual CPU cores or system average
• CPU Load Monitoring: Track CPU usage percentage across all cores
• Historical Data Visualization: Interactive graphs showing temperature and load trends over time
• Configurable Update Intervals: Adjust monitoring frequency from 1-10 seconds

User Interface

• Clean GTK3 Interface: Modern, responsive design using GTK3 framework
• System Tray Integration: Minimize to system tray with continuous monitoring
• Dashboard View: At-a-glance view of current system metrics
• Settings Panel: Comprehensive configuration options
• Temperature Unit Support: Switch between Celsius and Fahrenheit

System Integration

• Desktop Entry: Launch from applications menu with proper icon integration
• Auto-start Option: Configure to start automatically at login
• Start Minimized: Option to launch directly to system tray
• Configuration Persistence: Settings saved in ~/.config/coremon/

Advanced Features

• Threshold Alerts: Visual indicators when temperature or load exceeds configurable thresholds
• Individual Core Monitoring: Toggle between average view and per-core monitoring
• Smooth Graph Rendering: Optional smoothing for better visualization
• Window State Management: Remembers window size and position

Installation

Option 1: Debian Package (Recommended)

Download and install the pre-built .deb package:

sudo apt install ./coremon_1.0.0-1.2_amd64.deb

Option 2: From Source

1. Install the required dependencies:

sudo apt update
sudo apt install python3-gi python3-gi-cairo python3-pip python3-setuptools
pip3 install -r requirements.txt

2. Install CoreMon:

sudo python3 setup.py install

3. Launch CoreMon from your applications menu or by running coremon in the terminal.

Usage

• The main window shows current CPU temperature and load, along with historical graphs.
• Use the Settings tab to configure update intervals, temperature units, and startup behavior.
• When minimized, CoreMon will show temperature and load in the system tray.
• To close the application, right-click the system tray icon and select "Quit".
