Hi Roberto,

You will need a license to run nprobe. Please purchase one from our shop https://shop.ntop.org or contact us privately http://www.ntop.org/support/need-help-2/contact-us if you need a demo license.

Regards,

Emanuele

    Dear, I have a server with Debian 10 + Ntopng 3.9 + Nprobe 8.7 in
    "collector mode".

    My config is:

    /etc/ntopng/ntopng.conf:

    -G=/var/run/ntopng.pid
    -e=
    -i="tcp://127.0.0.1:5556 <http://127.0.0.1:5556>"
    -w=3000
    -m=172.31.10.0/24,179.0.141.0/24
    <http://172.31.10.0/24,179.0.141.0/24>
    -n=1
    -S=
    -d=/var/lib/ntopng
    -q=
    --community

    /etc/nprobe/nprobe.conf:

    -i=none
    --collector-port=2055
    --zmq=tcp://*:5556
    -n=none
    -T=@NTOPNG@
    -g=/var/run/nprobe.pid

    I start both service with "systemctl nprobe start" and "systemctl
    ntopng start".

    Everything is OK, I can see a lot of flows in Ntopng interface.

    But after some minutes, the flows decrease and they come to 0
    (zero), and this value remains just like this forever.

    Please can you help me ???

    Thanks a lot !!!
