I am in the stage of looking a NetFlow for our company and I don't know which one to pick. There are a lot of them out there, and one wonder which to pick or which one is best suited for your needs.
I have tested a couple of NetFlow PRTG, WANGuard and Scrutinizer. PRTG is great but it is so expensive, the other two are pretty fine. Now my question is, do you guys have any recommendation? And what is your experience with it?
We'd like to monitor everything (in production) and know why some servers are talking too much, etc. So bandwidth usage for servers/hosts, protocol (layer 2/3, etc. Going to use it on Cisco 3800 and ASA.
Edit: I know probably most of them are able to send email notifications and if it can send sms it would be even better.
