This means that your license is no longer valid. Very likely because it is older than 1 year. You should renew the maintenance. See: http://www.ntop.org/support/faq/how-can-i-renew-maintenance-for-commercial-products/ <http://www.ntop.org/support/faq/how-can-i-renew-maintenance-for-commercial-products/>

Simone

Hi Simone,

Yes it is in demo mode because it was purchased more than a year ago, is that the problem? I haven't reached the 25000 flows of demo mode...

Nprobe v7.4 in demo mode too receives a lot more of packets.

I would like to get it working before renew it.

Thank you in advance.

Kind regards,
Javi

This means that your license is no longer valid. Very likely because it is older than 1 year. You should renew the maintenance. See: http://www.ntop.org/support/faq/how-can-i-renew-maintenance-for-commercial-products/

Javier,

If I look at the collected packets and exported flows, they are absolutely comparable between 7.4 and 8.1

7.4:
> 18/Sep/2017 09:37:01 [nprobe.c:2722] Flow export stats: [2099368000 bytes/2538000 pkts][767 flows/26 pkts sent]
> 18/Sep/2017 09:37:01 [nprobe.c:2729] Flow collection: [collected pkts: 213][processed flows: 0]


8.1:

> 18/Sep/2017 09:50:38 [nprobe.c:3007] Flow export stats: [1083658 bytes/1294 pkts][796 flows/27 pkts sent]
> 18/Sep/2017 09:50:38 [nprobe.c:3014] Flow collection: [collected pkts: 217][processed flows: 0]


So maybe there's some sampled traffic that is not properly re-scaled and this results in smaller values. Indeed, if you look at v 7.4 bytes and packets, they both end with 000 so an x1000 rescale is likely.

Have a look and tune the following options:

[--sample-rate|-S] <pkt rate>:<flow rate>
| Packet capture sampling rate and flow
| sampling rate. If <pkt rate> starts with
| '@' it means that nprobe will report
| the specified sampling rate but will
| not sample itself as incoming packets
| are already sampled on the specified
| capture device at the specified rate.
| This setup is meaningful only for NetFlow/IPFIX
| as in sFlow this info is part of the packet.
| Default: 1:1 [no sampling]
[--collector-sample-rate] <value> | Specify the bytes/pkts collection sample rate (NetFlow only).
--upscale-traffic | In case of sampled traffic multiply the packets/bytes
| according to the sampling packet rate.
| (See -S for more information)

Simone

Thank you!

I added --collector-sample-rate 1000 and --upscale-traffic and now traffic is reported is fine.

So maybe there's some sampled traffic that is not properly re-scaled and this results in smaller values. Indeed, if you look at v 7.4 bytes and packets, they both end with 000 so an x1000 rescale is likely.

Have a look and tune the following options:

[--sample-rate|-S] <pkt rate>:<flow rate>
| Packet capture sampling rate and flow
| sampling rate. If <pkt rate> starts with
| '@' it means that nprobe will report
| the specified sampling rate but will
| not sample itself as incoming packets
| are already sampled on the specified
| capture device at the specified rate.
| This setup is meaningful only for NetFlow/IPFIX
| as in sFlow this info is part of the packet.
| Default: 1:1 [no sampling]
[--collector-sample-rate] <value> | Specify the bytes/pkts collection sample rate (NetFlow only).
--upscale-traffic | In case of sampled traffic multiply the packets/bytes
| according to the sampling packet rate.
| (See -S for more information)

Simone

Hi Simone,

Yes it is in demo mode because it was purchased more than a year ago, is that the problem? I haven't reached the 25000 flows of demo mode...

Nprobe v7.4 in demo mode too receives a lot more of packets.

I would like to get it working before renew it.

Thank you in advance.

Kind regards,
Javi

This means that your license is no longer valid. Very likely because it is older than 1 year. You should renew the maintenance. See: http://www.ntop.org/support/faq/how-can-i-renew-maintenance-for-commercial-products/

Simone
