A process monitor system that monitors all the active processes, with their corresponding process ids (PIDs), CPU usage, memory usage

Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. It combines the features of two legacy Sysinternals utilities, Filemon and Regmon, and adds an extensive list of enhancements including rich and non-destructive filtering, comprehensive event properties such as session IDs and user names, reliable process information, full thread stacks with integrated symbol support for each operation, simultaneous logging to a file, and much more

• System Data
  • Linux stores a lot of system data in files within the /proc directory.
• Operating System
  • Information about the operating system exists outside of the /proc directory, in the /etc/os-release file.
• Kernel
  • Information about the kernel exists /proc/version file.
• Memory Utilization
  • Information about memory utilization exists in the /proc/meminfo file.
  • how htop calculates memory utilization from the data in /proc/meminfo
• Total Processes
  • Information about the total number of processes on the system exists in the /proc/meminfo file.
• Running Processes
  • Information about the number of processes on the system that are currently running exists in the /proc/meminfo file.
• Up Time
  • Information about system up time exists in the /proc/uptime file.

• Build the project: make build
• Run the resulting executable: ./build/monitor The system monitor is reading the information from the system program and lists the operating system, kernel version, Total CPU utilization percentage in a bar representation, Total memory utilization percentage in a bar representation, total number of processes, number of running processes, and uptime. The system monitor displays the PID, user, CPU utilization, memory utilization, uptime, and command for each process.

• display basic data about the system and individual processes
• list at least the operating system, kernel version, total number of processes, number of running processes, and up tim
• display the CPU utilization
• display a partial list of processes running on the system
• display the PID, user, CPU utilization, memory utilization, up time, and command for each process.
• sory by CPU utilization and display PIDs according to sorted CPU utilization (high --> low)

• Calculate CPU utilization dynamically, based on recent utilization
• Sort processes(Pids) based on memory utilization as an optional choice(currently sort by CPU utilization)
• Make the display interactive
• Restructure the program to use abstract classes (interfaces) and pure virtual functions
• Port the program to another operating system(currently Linux)

• ncurses is a library that facilitates text-based graphical output in the terminal.
• This project relies on ncurses for display output.
