We're currently using ManageEngine Netflow but I've never been a big fan of it. We're also a Solarwinds Orion customer but I don't have the Traffic Analyzer component.
I'm definitely looking to make a change and wanted to see what you all recommend that I look at.
You could download a fully functioning 30 day demo and install it and test it out in your environment for free. I used Solarwinds NTA for several years.
Check the free tools as well just in case you need a replication of flows from the server they are being sent to currently. Instead of reconfiguring all of your devices shift your current Application port so incoming is the same and the forwarder can fwd to the adjusted app port as well as the Orion IP:Port configured. In a few cases, we have used the tool instead of a device reconfiguration.
Name: Flow Tool Bundle

It's really nice having the data on the same payne for review as well as alerting. Beyond that, there are ways to bring your segmented world into Orion NTA, next to seamless if you are using IPAM (latest versions).

Loop1 Systems: SolarWinds Training and Professional Services
Solarwinds Netflow Traffic Analyzer (NTA) is versatile, powerful, and flexible. You can find online resources in Thwack that describe exactly how to configure your L3 switches or routers or firewalls or access points / WLC's to send the right kind of data to NTA and have it displayed quickly and intuitively. I haven't found any Cisco equipment I couldn't look up in the Solarwinds online resources for Netflow, copy the configuration right out of the online resources, modify for source interface and destination polling engine, and then paste directly into the network equipments' configuration.
It's easy and it makes a wonderful impression on Managers & peers when you can spend a couple of minutes pasting new config lines into all your remote routers (you can do it in bulk via NCM), and then immediately start showing payback when you can see which circuits or interfaces have congestion or errors, and which internal sources are using most of the bandwidth, and where they're going to on the Internet.
NTA is a mighty fine tool, and if you don't have it, test it with the free 30-day trial. You can even tell them Rick sent you. ;^)
Swift packets!
