Hello! I also believe to use the right tools for each situation. So, I would suggest to use something like nodejs or golang for the "socket-required" part of your application! Good luck my friend!

Hello @Noctis17, sorry for my late answer. As @emilmoe also said "I'm sorry but my answer was in general, I have never worked with SNMP nor NMAP", but only theoretical in past . I hope to choose the right tools and make a nice project ;)

I think in this senario I wouldn't use php, probably I would try to make a golang or java application to handle the device management and also use this apps to build the backend server & api(restful, websockets for realtime updates) with a frontend framework/ecosystem like angular, react, vuejs etc..

Golang ;)
