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.
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…
What are your country hotspots for what kind of content? (e.g. if you primarily aquire movies, shows, anime, linux isos, misc.)
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.
There is also 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.
My UDM router does all of that.
Can’t you just use Kali for that?
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.
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/v3
Also, 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.

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?
