Hello! I am trying to collect netflow from a cisco 3850 and view it in ntopng. I am able to see some data, but it appears intermittent. When I view nprobe with -b 2 option it seems like the flows pause every few seconds then resume. The real time traffic in ntopng shows traffic, then nothing, traffic, then nothing. Am I missing a collection rate config or something?
ntopng enterprise and nprobe pro on same machine ntopng conf -w=3000 -W=0 -g=-1 -m="<mylocalnetwork>" -d=/storage/ntopng -G=/var/run/ntopng.pid -i=tcp://127.0.0.1:5666 --online-license-check nprobe -n none --zmq "tcp://*:5666" --collector-port 2166 -T @NTOPNG@ --disable-cache 04/Sep/2018 11:15:39 [nprobe.c:3297] L7 Proto Diff Total 04/Sep/2018 11:15:39 [nprobe.c:3311] Unknown/0 303.55 MB 741.98 MB 04/Sep/2018 11:15:39 [nprobe.c:3319] Current flow export rate: [131.8 flows/sec] 04/Sep/2018 11:15:39 [nprobe.c:3322] Flow drops: [export queue too long=0][too many flows=0][ELK queue flow drops=0] 04/Sep/2018 11:15:39 [nprobe.c:3327] Export Queue: 0/512000 [0.0 %] 04/Sep/2018 11:15:39 [nprobe.c:3332] Flow Buckets: [active=0][allocated=0][toBeExported=0] 04/Sep/2018 11:15:39 [nprobe.c:3369] Collector Threads: [871 pkts@0] 04/Sep/2018 11:15:39 [nprobe.c:3108] Processed packets: 0 (max bucket search: 5) 04/Sep/2018 11:15:39 [nprobe.c:3091] Fragment queue length: 0 04/Sep/2018 11:15:39 [nprobe.c:3118] Flow collection stats: [collected pkts: 871][processed flows: 19898] 04/Sep/2018 11:15:39 [nprobe.c:3121] Flow export stats: [0 bytes/0 pkts][0 flows/0 pkts sent] 04/Sep/2018 11:15:39 [nprobe.c:3127] Flow export drop stats: [0 bytes/0 pkts][0 flows] 04/Sep/2018 11:15:39 [nprobe.c:3132] Total flow stats: [0 bytes/0 pkts][0 flows/0 pkts sent]
