Re: Traffic sent and traffic received in historical view in ntopng

Hi Andrew,

You are right, network stats are calculated every minute, whereas 
interface stats are updated each second.

Please note that these stats are dumped to RRD files, not to the MySQL 
database.

For the "No results found" issue please open an issue on github with 
detailed information on software version and configuration used.


Note: the fact that in/out breakdown for interface traffic is not 
available is already tracked by issue 
https://github.com/ntop/ntopng/issues/1114

Regards,
Emanuele
