Hi Peter and Andrew,

Please see below.

I would like ntopng to be able to replicate those daily totals (to give confidence our data is correct), and then analyse the totals to see which devices contributed. Eg. If we have an above average daily total, I want to know why.
Ntopng can actually produce a traffic report where it shows the top 
local/remote talkers for a specified time frame (e.g. a day), but this 
is a pro only feature.

In enterprise version we also have a per host/network/interface report 
showing the total traffic in a day/week/month with comparison to the 
previous day/week/month.
Note: the traffic is not split into sent/received.

No, this is something different. MySQL database exports /flows/ as data, 
whereas RRD is /timeseries/ database, so they play different roles.
If you export to MySQL using the -F option, you can do your own 
computations and aggregations on data.

Right now you have the graphs on the network which show you the traffic. 
If you hover the graph with the mouse, a table on the right will appear 
and it reports the "Total Traffic" for the specified time frame (1d in 
your case).
But the graphs totals are not split into ingress/egress, so please open 
a feature request so that we can evaluate the proposal.

Emanuele
