Hi Nanog.... We are looking at replacing our Netflow collector. I am wonder what other service providers are using to collect netflow data off their Core and Edge Routers. Pros/Cons... What to watch out for any info would help. We are mainly looking to analyze the netflow data. Bonus if it does ddos detection and mitigation. We are looking at ManageEngine Netflow Analyzer PRTG Plixer - Scrutinizer PeakFlow Kentik Solarwinds NTA Thanks in advance...
