i have a few questions regarding this package.
1- i checked the option for "historical data storage" but i don't know how much storage is being used, where can i check that?
2- is there a way to delete historical data?
3- is it possible to get historical reports? for example, i want to see which host on my network used the most bandwidth in a month or between a specific set of dates.
that is all i can think of, right now. there were a few more questions i wanted to ask, i will add them if they come back to me.
edit- the counters for hosts/connections seem to reset after a certain amount of time. personally, i am not a fan of this. i wouldn't mind the current setup (of resetting the counter) if i was able to pull a report. this goes back to number 3, it would be helpful to see which host is using the most data. also, a list of sites accessed by host would be nice.
for the record, i realize this is a free tool and that i should look into other options if it doesn't work for me, i have no problem with that and i am happy with what i am seeing. i just want to make sure there isn't something that i am missing, that's all.

1/ To check ntopng disk usage, run
du -sh /var/db/ntopng
The thing accumulated 20GiB worth of data in 10 days. Crazy. ::)
2/ After your HDD got full after a month or so and you want to clean up the mess
- While ntopng is running (!!!) do:
# /usr/pbi/ntopng-*/local/bin/redis-cli 127.0.0.1:6379> FLUSHALL OK 127.0.0.1:6379> FLUSHDB OK 127.0.0.1:6379> exit
Stop ntopng service from the GUI.
# rm -rf /var/db/ntopng/
- Go to Diagnostics - ntopng Settings, untick Historical Data Storage (!!!), click Change.
3/ No, not in a usable way ATM. Noone wants to wait days for the historical data to load.
