This is a great feature. However, in your how-to it says:


     IPv4 and IPv6 Flows Tab

/On the right of the Chart tab there are four additional tabs. The first two visualize monitored flows in the selected time-span. If no IPv4 (IPv6) flows are present in the observation period, then the corresponding tab will be automatically hidden. /

I only see an IPv4 tab when I select 1 Day or more. The IPV4 Flows tab is not present for 12 Hours, 6 hours, 3 hours, 1 hours or less etc.... What am I doing wrong? There are flows... I've been logging to MySQL for weeks already, and the network is super busy. So why do I not see flows within the past 3 hours?

Thanks,
Warren

Hi, that is definitely possible.

You can have this kind of reports in the Professional version. You can generate historical reports (e.g., top applications / ip / AS / etc) as well as obtain detailed per-host reports. The latter requires MySQL flow export to be enabled.

See http://www.ntop.org/ntopng/exploring-historical-data-using-ntopng-part-2/

    Hello,

    just to be difficult, my second question is almost the opposite of
    my first.

    Is it possible to get an historical report for a specific IP
    address or a specific protocol over a given period of time?

    I'd like to see
    a) how much a particular machine has downloaded over a period of
    time, as well as
    b) how much traffic a particular protocol (eg youtube) has
    generated over a period of time.

    Thanks,
    Chris.
