Contents of /var/tmp/ntopng/

Dear ntopng experts,

Directory /var/tmp/ntopng/ contains 443K inodes (files and directories)
on my system, significant number of which (~20K) changes daily. This
number of small files slows down daily backup noticeably. Hence two
questions:
* What do I lose if I exclude this folder from backup?
* Since I have mysql connected anyway, can this data be stored there
instead?

With Best Regards,
Marat Khalili

You will lose historical time series

currently no, but we are working on a comprehensive flows+timeseries db that will be released in Q1 2018.

Marat
please note that in ntop 3.1 the number of files has been greatly
reduced and that we are working to reduce them up. If you are still
using v3 you can use 3.1 to preview this

Thanks Luca

In fact I'm on a v.3.1.171102 right now. Can it be that many of the
files are just a leftover from previous versions?

Yes it’s possible. You can delete the directory and start over: you will loose some history but everything will be clean
