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.
There’s also The Dude - although it’s a Windows-only application. But the visualisation is great.
Can it discover non Mikrotik devices?
The version I had played around with about 10 years ago could.
I’ve used about 10 years ago too, but I’ve heard that now it needs a Mikrotik device but I’ve nver had the time to test it

ntopng has all of that. I’m currently hosting it on my home router.
+1 for this.
You need to see all the data flowing through a sensor to be able to map it, so a router / firewall is often the central point.
I run it as an addon for pfSense and it’ll show me all sorts of info.
If you setup the GeoIP you can see which countries your network’s connecting too… interesting for torrents…
The closest project to this that I can think of would be Netbox
Netbox is a documentation tool. You can plug in Napalm to do some stuff but it mostly exists to catalog the intended state of the network.
It’s a wonderfully powerful tool, and Stretch has done a great job with it…but it’s not an analysis tool, it’s documentation.
Stretch is a pretty cool guy too. He strikes me as the kind of person that really wants to help colleagues “see the light” of the role Python and FOSS can play in network automation and maintenance. I respect that, a lot…finding enjoyment in the way you do things, and wanting to share that with other people.
There is also https://github.com/jokob-sk/NetAlertX
This is cool, thanks
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.
What are wanting to see and for what purpose?
Unknown unknowns
I’ll probably get boo’d but NetData covers just about everything I could want to monitor, and then some. If you don’t want to hook up to the mother ship, you can use the /v3 switch in the url on your homarr dash, or equal like:
https://netdata.mycoolserver.duckdns.org/v3Also, as has been mentioned, ntopng is pretty awesome as well.
Why do you expect boos? Something we should know about it?
Some homelabbers / selfhosters have very rigid concepts and opinions about what selfhosting and homelabing should be and what software should be used. I don’t have issues with NetData. It’s a great piece of software. Damn near covers anything I’d want to monitor, and then some. OP stated ‘network analyzer’ and while Netdata does have some analyzing components, it’s mainly a monitor/alert mechanism. So, I didn’t know how that would fit what they were looking for.

Depending on how you intend to use Kali, that’s either a bad idea or a terrible idea. Don’t use Kali bo for long running processes.
Just get a router with that feature or flash a firmware with that feature.
