Build a monitoring website to monitor various other website endpoints

-> This project is to build a website that can display GREEN upon 200 results and RED upon any other results to an html page calling various web endpoints using curl or any other methodology(eg:https://www.freelancer.com , [login to view URL], etc..) -> The webpage and the code base can be then deployed to an apache server hosted on Redhat linux. -> Endpoints will vary and get added later once the logic is ready. -> Backend logic can be written on the redhat linux server. -> The user interface should be refreshing periodically, say 15mins with the latest result on checking the endpoints again. -> Endpoints can be hard coded. -> Frontend logic can be written on Javascript. -> Customization of site is not important but functionality is important
