Do you have any recommendations for a self hosted network analyzer that can visualize all the device connected to a network, different subnets, etc, and perhaps show the flow of data for each network device?
I’m probably asking for too much but sometimes there are cool projects out there that aren’t easy to find.
SNMP monitoring can give you a realtime visualize all the device connected to a network, different subnets, etc, and show the flow of data for each network device.

also zabbix
There’s also The Dude - although it’s a Windows-only application. But the visualisation is great.
