Suricata Netflow export into ntopng

Hello, 

I am trying to see if we can export NetFlow data from Suricata and add them either to Nprobe or directly into ntopng ? 

Suricata seems to have a the ability to export flows directly in redis format. 
But I am not sure if ntopng has the ability to collect the JSON formated flows and store them directly in Redis or if we rather have to use Nprobe as a middleware formater. 


Any help is welcome. 


Sincerely yours.
