Title: External traffic analysis tool
Post by: jl_678 on November 19, 2017, 04:51:51 pm

Hi,

I like the analytics in Opnsense and am thinking about performing additional traffic analytics.  (Trying to review data usage by LAN client and understand the trends and those clients that might be using more than expected.)

Can anyone recommend an opensource tool that might help with this?  It would need to understand the exported data from Opnsense and ideally allow for more detailed analytics in an easy to use fashion.

Thank you in advance.

ntopng as a network collector, or you put it between your lan and OPNsense as a tap device.

Hi,

Thank you.  That looks like a tool that replaces the bandwidth reporting by Opnsense.  My goal is actually to find something that you can use the data exported by Opnsense to run different analyses on the data versus replacing the traffic analysis data with something else.  I suppose that I could do my own data analyses with something like Python, but I was hoping that someone had already developed something.

Thank you.

There's no actively maintained project for this.
You could use pmacct with a DB and write your own UI.

You could have a look at the free (as in beer) edition of Solarwinds: https://www.solarwinds.com/free-tools/real-time-netflow-analyzer

That Free Solarwinds tool looks very interesting.  I will check it out.  Thank you.
