netflow analyzer Apps.

[raindrop18]

I need some feedback about netflow analyzer to process big chunk of data per minute. I prefer open source software can run on *nix based server. but i am also open for commercial software.  looking to replace NetQos. thanks in advance for the feedback.

Several netflow collectors should be able to do this.  Many NetFlow solutions save 100% of the raw data received as indicated by the templates.  Please consider Scrutinizer 'Commercial' NetFlow Analyzer for billing.

I believe NetQoS is an applicance based flow processing tool which  gives it very high scalability. If you are looking for the same kind of  processing power, I am not sure if any open source will scale up to  that. But, one of the most famous open source tool is NTOP  (http://www.ntop.org/overview.html) and they have a commenrcial option  called nmon (http://www.nmon.net/shop/cart.php) which includes Linux and  Unix versions. This may help.

For commercial, there is ManageEngine's NetFlow Analyzer, Fluke Network's NetFlow Tracker, Plixer Scrutinizer and NetFlow Auditor.
