I've been looking at available netflow applications to use in conjunction with our edge internet routers mainly. What does everyone use? I'm trialling a couple that you have to pay for - do you think they're worth the money or could I make do with a free version?
I'm going to mainly use it to keep an eye on bandwidth, what's going on, which of our services use most etc. but eventually will also look at doing some billing based on bandwidth for external customers so need to keep that in mind.
Any advice or thoughts greatly appreciated.
