Now I am testing nprobe + dna drivers
and I see traffic lost (>30%) on 1Gb speed!
system:
-----------------------
CPU: Intel(R) Xeon(R) CPU E31230 @ 3.20GHz (# of cores: 8)
RAM: 8GB
Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network
Connection (rev 01)
-----------------------
-----------------------
pf_ring modules startup:
-----------------------
insmod $PF_RING_PATH/pf_ring.ko transparent_mode=2 enable_ip_defrag=1
min_num_slots=65536 enable_tx_capture=0
cat /proc/net/pf_ring/info
PF_RING Version : 5.5.2 ($Revision: exported$)
Ring slots : 65536
Slot version : 14
Capture TX : No [RX only]
IP Defragment : Yes
Socket Mode : Standard
Transparent mode : No (mode 2)
Total rings : 8
Total plugins : 0
-----------------------
Intel dna drivers startup:
-----------------------
insmod $DNA_DRIVER_PATH/ixgbe.ko MQ=1,1,1,1 RSS=16,16,16,16 mtu=16000
InterruptThrottleRate=4000
cat /proc/net/pf_ring/dev/dna1/info
Name: dna1

Address: 00:E0:ED:22:27:E9
Polling Mode: DNA
Type: Ethernet
Family: Intel ixgbe 82599
Max # TX Queues: 16
-----------------------
script that starts 8 instances of nprobe:
-----------------------
#!/bin/sh
NPROBE="/bin/nprobe"
for i in 0 1 2 3 4 5 6 7
do
$NPROBE -i dna1@${i} -w 512000 --cpu-affinity ${i} -P /home/data/${i} -b2 -G
-F 900 \
--flow-version 9 -T "%IPV4_SRC_ADDR %IPV4_DST_ADDR %IN_PKTS %IN_BYTES
%L4_SRC_PORT %L4_DST_PORT %PROTOCOL %FIRST_SWITCHED %LAST_SWITCHED"
done
-----------------------
in this configuration I have 30% of traffic loss on 1G channel
where is my mistake?
I'm sure it's something that I'm doing wrong but what exactly it is?
Thank you for any advice,
