Tracker

Tracker is a simple system monitoring software written in C++ using the SFML library. It provides real-time information about CPU usage, RAM usage, and disk usage.

Prerequisites

• SFML: The Simple and Fast Multimedia Library
• Windows.h: Windows API header file
• pdh.h: Performance Data Helper header file
• psapi.h: Process Status API header file

How to Use

1. Include the necessary SFML and Windows headers in your project.
2. Add the SystemMonitor class definition to your code.
3. Instantiate an object of the SystemMonitor class.
4. Call the init() method to initialize the system monitor.
5. Call the run() method to start monitoring the system.

#include "core.h"

int main()
{
    SystemMonitor tracker;
    tracker.init();
    tracker.run();

    return 0;
}

Class Members

Constructors and Destructor

• SystemMonitor(): Constructor. Initializes the window and sets up the text properties.
• ~SystemMonitor(): Destructor. Closes the query and releases the allocated resources.

Methods

• void init(): Initializes the system monitor by opening the query and adding the necessary counters.
• void makeWindowOnTop(sf::RenderWindow& window): Makes the window stay on top of other windows.
• int getCurrentValue(): Retrieves the current CPU usage value.
• std::string formatMemorySize(DWORDLONG size): Formats the given memory size in bytes to a human-readable string (e.g., "2.15 GB").
• void run(): Starts the system monitor's main loop, updating the window with the current system information.

Private Members

• PDH_HQUERY cpuQuery: Handle for the CPU query.
• PDH_HCOUNTER cpuTotal: Handle for the CPU total counter.
• PDH_HCOUNTER diskTotal: Handle for the disk total counter.
• sf::RenderWindow window: SFML window object.
• sf::Font font: SFML font object.
• sf::Text cpuText: SFML text object for CPU usage.
• sf::Text tramText: SFML text object for total RAM.
• sf::Text ramText: SFML text object for used RAM.
• sf::Text diskText: SFML text object for disk usage.

Feel free to modify the code to suit your specific requirements.
