NetFlow v9 with Wireshark

I need to monitor some network traffic to find out why the network has slow performance from time to time.

I cant find any information about Wireshark supporting NetFlow v9.  Does it support NetFlow? and could you provide some documentation on configuring Wireshark for recieving NetFlow.

If Wireshark does not support NetFlow, what other FREE software could be used for this?  I have been looking at Whats Up Gold but to me it looks like you need to purchase a license for this?  Also, I am not sure if Solarwinds supports NetFlow in the demo version.

Any info is welcome.

Thanks

Wireshark does not support Netflow the way you want to use it.

PRTG is good, I believe that http://www.manageengine.com/ has a NetFlow client that is free for 30 days.

If you know and support Linux, then NTOP is free.
