Hello guys.
I am interested in good software for traffic flow (net flow) data analyse.
I know about ntop, but I think it’s not for thousand users and gigabites of traffic. I tried ManageEngine netflow analyzer too but it’s working on java and it’s very heavy, crushes frequently etc.
What will you recommend?
+1. Any ideas?

Thanks for replies hello again 
We implemented Manageengine Netflow Analyzer 9 in our network. Mikrotik traffic flow is working good with it.
But I have a question. How can i send BGP AS information to netflow analyzer? Here is tutorial for Cisco http://www.manageengine.com/products/netflow/help/cisco-netflow/cisco-ios-netflow.html
In mikrotik traffic flow page ( http://wiki.mikrotik.com/wiki/Manual:IP/Traffic_Flow ) is written that "Currently RouterOS does not include BGP AS numbers. "
But maybe there is some way to do this?
