Hi,

I'm working on a solution with Nprobe in proxy mode in order to receive
Netflow datas from routers and the export the analyzed information to
ElasticSearch.

It's doing well, but I didn't succeed to have Geolocation of the Public IP
src/dst.
I can see the country and city in the Json export with the use of Maxmind
data files.
I also configured the Json Template mapping for Nprobe.
So all is doing well but no GPS coordinates apears anywhere.

I trired with Ntopng in the same condition (with Maxmind file) and it's
working well. Kibana is able to receive the GPS coordinates in the right
format.

So I don't understand the difference in the export format with both of
these software.
Same for the AS name, it doesn't work in Nprobe but fine in Ntopng.
Ntopng is not able to export L4 protocol name and in general far less
information than Nprobe to Elasticsearch.

I read that we can send Json datas directly from Nprobe to ELK, but if so I
need to use Logstash. I don't think it's the solution as Logstah can be
used by itself to read Netflow trafic and treat the information to
translate IP to Geolocation, As numbers to Name, etc..



Thank you,
Christophe
