A solution for evaluating and using Netflow and sFlow data has been on the horizon in the Nagios Labs here for a while, and we are now calling for public beta testers for the product. If you would be interested in beta testing such an application please note your interest in the comments below and I will contact you so that we can work together to resolve issues that present themselves in Nagios Network Analyzer.
Nagios Network Analyzer has direct integration with Nagios Core and Nagios XI, and is designed to be used in conjunction with either, while still containing enough of its own features to be functional as a standalone application. It is also designed be very intuitive to use, and to browse your flow data in as straightforward and painless a manner as possible, without sacrificing flexibility.
