Hi Luca, The switch is a Huawei S6720 and it sends sflow data to nProbe. It's a fairly powerful switch, I don't think it has problems sampling data. I don't see any drops in the graffic. How can I check if I have drops in nProbe? Best regards, Dan Craciun On 15-Jan-19 22:17, Luca Deri wrote: > H

Hi Dan, in essence ntopng is collecting flows via nProbe, right? If so, please check 1. if the router is exporting flows out of 7 Gbit of traffic. usually for such high speeds routers are unable to export the whole traffic 2. do you see any drops on nprobe? Regards Luca > On 15 Jan 2019, at 20

Hello, I'm using ntopng Enterprise/nProbe Pro. I have a switch setup to send only the flows from one 10G interface to the nprobe machine. In the traffic dashboard there are some graphs, but I don't know what they signify. If you look in Cacti, the traffic is about 7.7Gbps. In ntopng is 2.03Gbps?

Hi, When I get the data issues ironed out (see previous thread), I am also having a hard time how to actually create the kinds of reports we need. The Netflow traffic received by nprobe is aggregate traffic consisting of traffic from all our remote locations, showing each individual device insi

Gerard, When you say wildly inaccurate, are you referring to the realtime charts in the dashboard only? I would expect them to be somehow inaccurate due to the nature of NetFlow, but once you visit the historical pages then totals and speeds must be accurate. Try and visit the historical chart
