[ntopng] host bandwidth historical graph

[fabienfs]

Hello,

I use ntopng on my router at home to be able to analyze which host consumes what in bandwidth in a chart :

I installed the same package ntopng on the same version of pfSense on another router, and I do not have the history of bandwidth per host :-( I don't have this same button :

My config :

How is this possible ?

Thanks for your help

Best Regards,
Fabien
