Re: Update frequency in Top Hosts (Local) and other places

Hi,

If you go into the network interface settings (through the cog icon 
into the network interface page) you can configure the "Realtime Stats 
Refresh Rate" to match your ASA exporter interval. Please note that 
this will affect the dashboard refresh rate but not the top hosts page.

The Top Hosts page is still rudimental. Please feel free to open 
enhancement issues on our github page https://github.com/ntop/ntopng .

Regards,
Emanuele
