Solarwinds Enters the NetFlow Fray...for Free?
Netflow has always been a topic of interest to me. It allows Cisco devices to track exactly how your network bandwidth is used. For example, using NetFlow allows me to see the applications (ports) using my Internet connection, how much bandwidth they are consuming, the source and destination IP addresses that are consuming the most traffic, and so on. Handy information!
Anyhow, Solarwinds has just released a new (free) tool that allows you to chart and graph all this information. This is definitely a plug for their enterprise Orion software which lets you manage bunches of devices...but hey, a free tool is still a free tool :).

I haven't downloaded it yet but it looks like it only records up to 60 minutes of data. :(
Still looking for that holy grail of free and open source netflow analysis.

Have u guys ever checked Intermapper?

Scrutinizer has a demo that records up to 24 hours. There's also another one (I've forgotten the name) that I think it fully functional, but for only 2 or 3 interfaces. I don't know how they compare to this one though, I'll have to check it out, thanks.
All the free netflow products seem to have a catch :( I'm hoping one day we can get a decent free and open source one out there.. there is certainly a lot of interest.

I haven't played with this much at all since I now have a commercial product for the purpose but it might be worth checking out:

Intermapper = only free for 14 days.
The VMWare appliance looks interesting but it's basically just a packaged version of CUFlow. There are a number of older OS Netflow softwares but they seem to be universally difficult to setup and maintain. Makes me think of the original MRTG days but 10 times harder.
No, we need an OS Netflow app on the level of Scrutinizer or pretty darn close to it. No, I'm not a programmer. I just like to make demands of them! :)
