Right now, in the iface with less traffic im having more than 68% of
dropped packets and it is not showing the real bw usage.
In the iface with more traffic im having like 96.98% of dropped packets.
I've upgraded to the last version of nightly builds and in both
interfaces Family is PF_RING.
My configuration is:
cor@ntopng:~$ cat /etc/ntopng/ntopng.conf
-n=3
-w=3010
-W=0
-m="84.*.*.0/23,185.*.*.0/22,5.*.*.0/24,94.*.*.0/24,178.*.*.0/24,178.*.*.0/24,185.*.*.0/22,185.*.*.0/22"
-A=1
-E=all
-D=all
-S=all
-X=524288
-x=262144
-d=/storage/ntopng
-C
-G=/var/tmp/ntopng.pid
-i=eth1
-i=eth2
And is made from nbox.
Thanks,

When host usage is 100% what is the process(s) that are causing the
usage? Is it ntopng or something else?

Hi Jospeh,
host resource usage is 100% almost 100% of the time. I tried with and
without PF_RING with same result.
Capture NICs are Intel Corporation 82541GI Gigabit Ethernet Controller

Whats the host resource usage when you are seeing the packet
loss? When you select the interface from ntop dashboard does it
show it using PF_Ring?
I have a box that captures on 2 10gig interfaces at around 30K pps
(just a subset of traffic) but it’s a pretty beefy box.
What is your capture nic?

Thanks in advance!

Hi all!
Im bumping this. We want to buy the Pro version, but firts we
want to test the community one.
At this moment, we have a 4x Intel(R) Xeon(TM) CPU 2.80GHz
with 2Gb RAM and 35Gb SCSI RAID1 in Ubuntu 12.04
We've installed nbox to control ntopng.
With this configuration, we have more than 50% of packet drop
and a few issues.
While I have this: *8,436 Hosts*
<http://185.29.68.24:3010/lua/hosts_stats.lua>*254
Aggregations*
<http://185.29.68.24:3010/lua/aggregated_hosts_stats.lua>*14,101
Flows* <http://185.29.68.24:3010/lua/flows_stats.lua>
If I go to Hosts -> Networks only 2 of my local networks
appear while I have configured 8 local networks. The 2 ones
who appear in the Networks, are always the same (the 2 first
configured in the -m option) and if I go to Hosts -> Hosts,
only 40 hosts appears in the list.
In Flows, only 1825 flows appears.
I'm doing something wrong? All that info was only monitoring 1
interface. If I setup to monitor the 2Gb interfaces,
packetdrop grows and interface get really really slow.
What kind of hardware do I need to monitor both interfaces?
Or, maybe, what kind of hardware configuration? P.E. Do i need
3 servers, 2 for nprobes and 1 for ntopng?
We are planning to move to a 10G in the next year, so please,
take that also into consideration.
We know with the Pro version we can do some kind of traffic
shaping, take that into consideration too.
Without all that info, we cant buy the ntop licenses.
Thanks in advance and Best Regards,

Hi All,
What hardware or kind of configuration do you recommend for
monitoring 2
Gb interfaces (port mirror mode)?
Thanks in advance!!!
