No traffic analyze on kafka interface about ntopng HOT 3 OPEN

Yes it is normal that some topics are not used. CAn you please check if nprobe in injecting flows into kafka and ntopng is unable to read them, or if the problem is that in your case nprobe does not produce flows? Did you check if you have valid licenses and not running in demo mode?

from ntopng.

As of the topic error message did you create the following topics

static const char *message_topics[] = {
"flow", "event", "counter", "template", "option",
"hello", "listening-ports", "snmp-ifaces", "message", NULL};

?

Can you share a complete ntopng startup log?

Hi @lucaderi

Can you please check if nprobe in injecting flows into kafka and ntopng is unable to read them, or if the problem is that in your case nprobe does not produce flows?

Nprobe exports flows to kafka, Ntopng reads them. But only core fuctionality works. Flows apeears on live, and that's all.

Did you check if you have valid licenses and not running in demo mode?

Valid.

As of the topic error message did you create the following topics?

Nprobe automatically created all 8 topics after start, but errors in Ntopng reading kafka.

Can you share a complete ntopng startup log?

Unfortunately no, deployment reconfigured to use ZMQ, no kafka at now.
