Re: nProbe / ntopng in large home network

I have the following network setup in a large community house with 24
users, each of whom have 2-7 devices who all use it exvlusively to connect
to the Internet:





As you can see I am slowly replacing cheap unreliable hardware with more
reliable Cisco equipment.



I’d like to better understand the traffic flows to improve performance and
it looks like nProbe and ntopng could help with this.



I have read few articles posted over a number of years about running nProbe
and ntopng on low cost hardware. Has anyone got any advice about:

1.       whether nProbe/ntopng is the right solution for our house (on a
budget) – am I barking up the right tree?

2.       The architecture – should I connect a nProbe / ntopng node to the
router and port mirror the port running to the switch? I would like to
avoid adding a point of failure which would be introduced using the similar
solution of putting the nProbe between the switch and the router or router
and internet proposed here
<http://www.ntop.org/nprobe/how-to-build-a-100e-augmented-netflowipfix-probe-ubiquity/>
.

3.       up-to-date advice about suitable low cost hardware which can run
both nProbe and ntopng and handle the volume of traffic.



Thanks very much,



Dan
