Create or edit php software to create ping software

General information for the website: pinging software Description of requirements/features: We are after a system which can send ping requests and various other requests so that we can monitor servers and display basic information such as latency and up time/downtime etc. We have come across https://www.phpservermonitor.org/ which is fully open source. We have had a play and it meets 90% of what we want from it. There are however, some changes that would have to be made for it to make our needs. It would have to: A: Be able to group servers together for companies. EG: instead of having 50 hosts spamming the overview page it will say something along the lines of: ([Company name] - 48/50 host reachable.) B: Be able to import data of servers in from a .CSV (or similar) file OR EVEN BETTER, pull the data from a Google drive excel sheet. We are not tied to using this piece of software of course. So we have two paths forward... 1. Edit the software to meet the requirements we have 2. Write a new piece of code from scratch which meet requirements. We are open to all opens. Please can you provide a your opinion on which you would prefer to do and costings associated for it. Kind regards Daniel Extra notes:
