Hello all,

I read the FAQ and frequently search the mail archives but must have
missed the info if it was there.  So sorry in advance if that is the
case.

I need some advice from you experts.  I'm implementing a system that
will dump a daily snapshot of ntop's accumulated data during that day
(something like Shawn Wall's Daily Report system
http://prdownloads.sourceforge.net/ntop/NTOP_Usage_Tracking.pdf?download)

So I setup a cron job that resets ntop at 00:00 everyday.

then, I setup a cron job that dumps ntop data since last reset
(midnight) into a text file at 23:59 (end of day).

Finally, I setup a cron job which will run a java app which will import
everything into a PostgreSQL DB (or any other DB on any platform)
thereafter.  (With the sticky hosts option 'on' as to not lose any data)

Finally, I will automate email reporting to staff on simple yet useful
information I can extract from the DB (total download per hosts, total
download for whole network, trigger events when over defined limits...)

2 questions:

1) Does this whole idea make sense? (provided ntop server WILL run 24/7)

2) Can I just add the 'bytesRcvdFromRem' value of the data dump feature
of all hosts on the network to get the total external download of the
network (we have a monthly download limit)?

Or am I misunderstanding some basic concepts here?

Exact precision is not a requirements.

Using Ntop latest version on Fedora Core 5. 

Thanks is advance for your time
