CppND-System-Monitor

Starter code for System Monitor Project in the Object Oriented Programming Course of the Udacity C++ Nanodegree Program.

Follow along with the classroom lesson to complete the project!

Udacity Linux Workspace

Udacity provides a browser-based Linux Workspace for students.

You are welcome to develop this project on your local machine, and you are not required to use the Udacity Workspace. However, the Workspace provides a convenient and consistent Linux development environment we encourage you to try.

ncurses

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

Within the Udacity Workspace, .student_bashrc automatically installs ncurses every time you launch the Workspace.

If you are not using the Workspace, install ncurses within your own Linux environment: sudo apt install libncurses5-dev libncursesw5-dev

Make

This project uses Make. The Makefile has four targets:

• build compiles the source code and generates an executable
• format applies ClangFormat to style the source code
• debug compiles the source code and generates an executable, including debugging symbols
• clean deletes the build/ directory, including all of the build artifacts

Instructions

1. Clone the project repository: git clone https://github.com/udacity/CppND-System-Monitor-Project-Updated.git

2. Build the project: make build

3. Run the resulting executable: ./build/monitor

4. Follow along with the lesson.

5. Implement the System, Process, and Processor classes, as well as functions within the LinuxParser namespace.

6. Submit!

Project Specification

• Basic Requirements
  • The program must build an executable system monitor.
  • The program must build without generating compiler warnings.
  • The system monitor must run continuously without error, until the user terminates the program.
  • The project should be organized into appropriate classes.
• System Requirements
  • The system monitor program should list at least the operating system, kernel version, memory utilization, total number of processes, number of running processes, and uptime.
  • The System class should be composed of at least one other class.??
• Processor Requirements
  • The system monitor should display the CPU utilization.
• Process Requirements
  • The system monitor should display a partial list of processes running on the system.
  • The system monitor should display the PID, user, CPU utilization, memory utilization, uptime, and command for each process.
• Suggestions
  • Calculate CPU utilization dynamically, based on recent utilization
  • Sort processes based on CPU or memory utilization
  • Make the display interactive
  • Restructure the program to use abstract classes (interfaces) and pure virtual functions
  • Port the program to another operating system
