[gentoo-server] Network Monitoring Packages eg:ntop

[Ow Mun Heng]

Hi All,

Just want to see if anyone has any good info to share.

What I want: (not necessary host availability/polling)

Network monitoring/network traffic analyser which is something like ntop
which shows IP traffic in (from where) and out (to where) as well as top
talkers, top ports etc. This is basically to determine whats happening
with my network and who's been hogging the bandwidth etc. (time for some
wrist slapping!!)

And preferably it logs into a Mysql/Postgressql database which can be
later dissected for analysis.

I've looked at opennms - http://bugs.gentoo.org/show_bug.cgi?id=51441
which seems to be able to do it. 

I've also looked at jffnms, (which used to be in portage? searched
through the archives and it seems it was previously) but it seems to
only be able to look at host/server availability.

Looked at argus, it seems to have the features for Traffic Flow Analysis
but it does not support (AFAICT) for logging into a DB.(The FAQ states
answer is coming)

Zabbix is another package but seems like it too provides for
client/server availability etc. Doesn't do much for my needs.

I initially looked at ntop, then found out that it no longer uses a SQL
database for it's backend data collection, it now uses rrdtool. I've got
some stupid question, I understand that RRDtool is a good thing since
it's like a never growing DB, but frankly, just how many days/years of
data can it hold? What's the limit etc? I don't seem to be able to
locate a FAQ about that one particular point.

Appreciate some comments.

Thanks
