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.
This really depends on your network hardware. At a minimum it’ll need to support snmp and you can build something in zabbix, or preferably it’ll support netflow.
