Thanks for that. I've also discovered I can separate out the netflow data coming from each office's router using dynamic network interfaces. I followed the instructions provided at https://github.com/ntop/ntopng/issues/1444 to enable Probe IP disaggregation criterion, and to add %EXPORTER_IPV4_ADDRESS to the template. I assume this does the same thing as host pooling, assuming one wants to pool every subnet on each router? I have this running now, so I can't try creating host pools unless I undo those changes.
One thing I've noticed with dynamic interfaces is that if I select one, then click on the chart icon, the traffic peaks seem way too high. Eg 85Mbps when we only have a 14Mbps link. If I click on Hosts/Networks, and select one of the local subnets, it seems ok. Is there something wrong with that combined chart? Is it possible to name the dynamic network interfaces so I don't have to keep a list of all the routers' ip addresses? > -----Original Message----- > From: ntop-boun...@listgateway.unipi.it [mailto:ntop- > boun...@listgateway.unipi.it] On Behalf Of Simone Mainardi > Sent: Tuesday, 13 February 2018 1:29 AM > To: n...@unipi.it > Subject: Re: [Ntop] Combining subnet statistics > > Yes, you can do that. > > You should create an host pool for any branch you are interested monitoring. > An host pool can be defined as a set of subnets so this will do the trick. > Once > you've created the pools, visit the ntopng preferences and enable the > timeseries creation for them. > > Simone > > > On 12 Feb 2018, at 00:08, Peter Shute <psh...@nuw.org.au> wrote: > > > > We have several subnets in each of our branch offices that can use our > WAN.
