sflow direction on AOS-S?

    I have sflow configured but can't seem to differentiate between up- or downstream traffic.
    Is it possible to configure sflow for a certain traffic direct (say, incoming to the port only) on AOS-S switches?

    To answer my own question:
    This seems to be dependent on the tool used as sflow collector.

    PRTG does not seem able to differentiate ingress or egress. 
    InMon sFlowTrend (https://inmon.com/products/sFlowTrend.php) however is able to differentiate switch, port and in- vs egress without any additional config. As a downside, it requires java and seriously needs a UI update.

    Is it a single port you want to distinguish between up and download?

    Then you can use the filter options in prtg one sflow sensor for interface inbound and one for interface outbound...

    Not sure if it is the same for aruba, but manageengine netflow analyzer was a great tool. I worked with it a couple of years ago, and it was much better then the build in sflow/netflow in prtg or solarwinds. But today it looks like it is not a standalone tool, only embedded in the OPmanager/OPutils Kit. And it is not cheap... But take a look for yourself.
