ADVISE NEEDED - A Network Monitoring solution with WebInterface

A teacher asked me to build a network monitor using my raspberry pi. I do not have to code it. The Monitor should have:
-A beautiful web interface
-It should show a device counter (how many devices are in the network)
-and preferably show that in a beautiful graph.

What it does not need:
-Bandwith counter/monitor etc.

On what will it run:
-RaspberryPi 2
-Raspbian Stretch
it will be connected to the network with a ethernet cable

it should run headless
it should be a prebuilt solution, nothing confusing like Grafana.

Best regards

Niklas

Off hand, I don't know of a program to do what you require. But my Fritz box modem/router does just that. I'd start by looking for things to monitor DHCP Connections, and run a DHCP server. But I don't want to do your homework for you :-). You can't rely on the knowledge of others.

Its not any kind of homework. I manage the servers at our school and he asked me to find a software that can do it. I don't know in which environment you work, but we don't use a FritzBox for our 800+ client load xD

Sorry. When you wrote "A teacher asked me . . " I jumped to a wrong conclusion. There must be DHCP Monitoring software.

I see what you mean by "a teacher asked me..." and you even emphasize you don't want to code. But we are a little sensitive here about people asking us to do homework.

Anyway, check this: http://dhcpstatus.sourceforge.net/

It seems it does your task. Just don't know if it qualifies for "beautiful".

Creating graphics for web pages is a PITA. Because there are so many options you can't avoid coding or at least serious configuration. You might want to check out Google graphic tools. https://developers.google.com/chart/

I only need a software that does device discovery, and that in a web interface that shows number of devices in network in a graph

My bad, I thought you wanted to monitor the raspi host.

Zabbix, Nagios, Cacti.

Whether or not they do discovery, is your homework assignment.

I see that this question is several months old. I just want to let you know that Zabbix will suffice for your needs. The discovery process is very intuitive and can be used for small networks or very robust enterprise networks.
