Hi,
Currently ntopng does not export such daily information via an API. Feel
free to open a feature request on github https://github.com/ntop/ntopng
for an API request.
As an alternative, if you have MySQL support enabled (see -F option),
you could perform manual MySQL aggregations from the database.
Another alternative is to read data from the RRD files which ntopng
creates every 5 minute for local hosts (see -m option for defining local
networks). In this case, you could read the statistics of the host
192.168.1.1 with the command "rrdtool fetch
/var/tmp/ntopng/0/rrd/192/168/1/1/bytes.rrd AVERAGE -s now-1d". The
first column of the output contains the downloaded host traffic, while
the second the uploaded traffic.
This approach has the following implications:
- data is actually an average of the host traffic in 5 minutes, not the
actual traffic
- data is not aggregated, you will need to sum up the rows values to get
the total
- you will need to multiply the row value by 300, since values are derivates
See https://oss.oetiker.ch/rrdtool/doc/rrdtool.en.html for more details.
Regards,
Emanuele

Hi,
I'd like to collect of clients downloaded data per IP every day so
I'll integrate it for home made quota management per IP.
How can I get the data of total bytes from an API or cli from ntopng?
thanks.
