Netflow analyzer

I collect netflo records with flowd opensource netflow collector. Flow version is 9. I would like to do some analysis on the collected data. Does anybody know a very good tool for this issue? If it's possible I prefer opensource..

Thanks your help in advance

bye

Re: Netflow analyzer

Try out our software Caligare Flow Inspector, it has implemented huge statistics. You can also access directly to the MySQL database and select what you want... (http://www.caligare.com/netflow/cfi.php)

Re: Netflow analyzer

you can use Netflow analyser from Adventnet.

We use it but have configured a flow version of 5. I dont know whether it suports version 9 though

Re: Netflow analyzer

Hello,

I'm sorry, but I thing that Netflow is NOT supported on this box.I think that netflow is not supported on the following series: 2900, 3500 and 3750. On the 4000 series you need a special netflow card.

Have a nice day,

Re: Netflow analyzer

I knwo that you can configure netflow on this box, but no netflow exports are generated. Before 2 years I tested 3550 box and this box sent some netflow exports, but not all (I tip that only information about first "routed" packets, I think that rest of the flow was switched and these packets wasn't included in the netflow). Last year we upgraded IOS and netflow was configured, but there weren't any netflow packets.
