[1.0.0] - 2024-09-09

Added

• CPU Monitoring Feature: Added the ability to monitor CPU usage using the /proc/stat file.
• Memory Monitoring Feature: The program can now monitor memory usage using the /proc/meminfo file.
• Telegram Bot Integration: Full integration with the TgBot library to send CPU and memory status messages to a specified Telegram chat.
  • /usage command: Sends a detailed report of the CPU and memory status to the user.
  • /help command: Displays a list of available bot commands in Telegram.
• Telegram Notifications: Sends alerts to Telegram when CPU or memory usage exceeds defined thresholds.
• JSON Configuration Support: Added the ability to read and use a settings.json file for configuring key values like bot token, chat ID, CPU, and memory limits.
• Logging System: Implemented a logging system to log important activities and events using the log() function.
• Multithreading: Utilized multiple threads to run CPU monitoring, memory monitoring, and Telegram bot simultaneously for improved performance.

Changed

• Updated the log() function to log precise timestamps along with event messages.
• Improved Telegram bot stability by implementing restart mechanisms in case of errors.
• Adjusted default CPU and memory check intervals to 500 milliseconds for more frequent monitoring.

Fixed

• Fixed the issue with accessing /proc/stat and /proc/meminfo files on certain systems.
• Corrected the improper CPU percentage display in Telegram output.
• Enhanced readability and formatting of logs by using std::put_time to format dates and times more effectively.

Known Issues

• If the settings.json file is missing, the program exits without displaying an appropriate error message.
• The program may not work properly on systems that lack /proc (such as certain virtualized environments).
