[Ntop] Wrong Traffic Numbers after upgrade from 2.5 to 3.1

Discussion:

Hi all,

yesterday i upgraded our ntop and nprobe from 2.5 to 3.1. Now it shows
absolute wrong traffic numbers. As example we have machines constantly
doing 4 to 10 gbit/s and all it shows now for all hosts is 2 kbit/s up to 1
Mbit/s thats all.

We use normal nprobe where our arista switches send data too as it was
before with 2.5

nprobe --zmq tcp://*:5557 -i none --collector-port 6343 --verbose 2
--dump-stats

We had issues with 2 before with wrong traffic and arista switches which
was solved after reporting that to the list.

ah that did the trick. Thank you

Enrico,
If I remember correctly, your Arista switches are sending sFlow. So please
try to add nProbe option* --upscale-traffic* that will adjust the traffic
on the basis of sFlow sampling rates.

Same behavior now with the new upgrade from 3.1 to 3.3 ;) And im stil using
upscale-traffic :(

nprobe --upscale-traffic --zmq tcp://*:5557 -i none --collector-port 6343
--verbose 2 --dump-stats -V9

it shows me riddicolous traffic numbers now from my arista switch with
speeds of 70Gbit/s on single ports that dont even do 1G and so on. if i
remove upscale it looks better. Why does that behavior change every x
versions? ;) Im not sure if anything is on top to correct at all in ntop
any more.

ok correction, even without upscale it shows wrong numbers. seems like i
need to revert to an older version for now :(

Hey,

the interface status page does not show any dropped packets or blocked
flows. Also --disable-sflow-upscale doesnt help then it shows 1.79 TBit/s
for hosts as example. Its like back to the arista problem we had with 2.x
which got patched after i provided a dump.

Enrico,
Can you please verify, under the interface stats page, if there are sFlow
drops reported?
If you want to try and disable upscale on the latest 3.3, you can try with
--disable-sflow-upscale | Ignore sFlow sampling rate (1:1 is
used) and thus
Simone
ok correction, even without upscale it shows wrong numbers. seems like i
need to revert to an older version for now :(

Enrico,

We have made some fixes. Can you please hold a couple of hours (a new build
is in progress) and test again? If you still experience issues, please
consider sending us an sFlow capture or access to the machine.

Thanks,

no yet, will do later today. Thanks for the reminder. Wasnt aware new
packages are already up

Enrico, I was wondering if you had the chance to try new packages. You can
just run an upgrade of your package manager to get the latest version...
Thanks

I managed to get this updated now. It looks ok now with numbers but i had
to remove the upscale flag. With upscale flag it only shows a few kilobytes
instead of gigabits, so kind of reversed ;) But numbers seem to match
actual traffic now

Post by Enrico Kern
no yet, will do later today. Thanks for the reminder. Wasnt aware new
packages are already up

Enrico, I was wondering if you had the chance to try new packages. You
can just run an upgrade of your package manager to get the latest version...
Thanks
Simone
Sure. Tell me when new packages are out and i give it a go.
Enrico,
We have made some fixes. Can you please hold a couple of hours (a new
build is in progress) and test again? If you still experience issues,
please consider sending us an sFlow capture or access to the machine.
Thanks,
Simone
Hey,
the interface status page does not show any dropped packets or blocked
flows. Also --disable-sflow-upscale doesnt help then it shows 1.79
TBit/s for hosts as example. Its like back to the arista problem we had
with 2.x which got patched after i provided a dump.

Enrico,
Can you please verify, under the interface stats page, if there are
sFlow drops reported?
If you want to try and disable upscale on the latest 3.3, you can try with
--disable-sflow-upscale | Ignore sFlow sampling rate (1:1 is
used) and thus
Simone
ok correction, even without upscale it shows wrong numbers. seems like i
need to revert to an older version for now :(

Post by Enrico Kern
Same behavior now with the new upgrade from 3.1 to 3.3 ;) And im stil
using upscale-traffic :(
nprobe --upscale-traffic --zmq tcp://*:5557 -i none --collector-port
6343 --verbose 2 --dump-stats -V9
it shows me riddicolous traffic numbers now from my arista switch with
speeds of 70Gbit/s on single ports that dont even do 1G and so on. if i
remove upscale it looks better. Why does that behavior change every x
versions? ;) Im not sure if anything is on top to correct at all in ntop
any more.

Post by Enrico Kern
ah that did the trick. Thank you

Enrico,
If I remember correctly, your Arista switches are sending sFlow. So
please try to add nProbe option* --upscale-traffic* that will adjust
the traffic on the basis of sFlow sampling rates.
Simone

Post by Enrico Kern
Hi all,
yesterday i upgraded our ntop and nprobe from 2.5 to 3.1. Now it
shows absolute wrong traffic numbers. As example we have machines
constantly doing 4 to 10 gbit/s and all it shows now for all hosts is 2
kbit/s up to 1 Mbit/s thats all.
We use normal nprobe where our arista switches send data too as it
was before with 2.5
nprobe --zmq tcp://*:5557 -i none --collector-port 6343 --verbose 2
--dump-stats
We had issues with 2 before with wrong traffic and arista switches
which was solved after reporting that to the list.
