No, it is also available in the community version.
It should be enabled by default, please verify that the "Traffic" preference under "Data Retention" settings is enabled.

Note: local networks data is dumped to disk each 5 minutes.

It's the ingress/egress bytes _per local network_ which I am interested in. Thank you - I have found this now.

However, it is showing no data. I think this is a licensed feature?

    The graph at the link shows *host* traffic, which indeed is split
    between sent and received. The *interface* graph instead does not
    make such a distinction.

    In ntopng we have graphs for:
    - interfaces: total bytes
    - local hosts: sent, received bytes
    - local networks: ingress, egress, inner bytes
    - .. and others

    If you really want *interface* traffic to be split, please open a
    feature request on our github page https://github.com/ntop/ntopng.

    shows exactly this information. However my own installation shows
    a similar graphic, but without the 'traffic (Sent)' and 'traffic
    (Recvd)' designations.

        Hi Andrew,
        Currently ntopng saves the interface RRD data as the total
        number of bytes, so it not possible to get a differentiated
        sent/received view.
        However, you can get such differentiated metrics from the
        Local Networks page.

        Can someone please tell me what I need to do to get
        differentiated traffic sent and received in the 'historical
        view' on an interface?

        Thanks in advance.

        Andrew
