I have a Netflow router sending data (debugs prove this), but Netflow server not gathering data and showing on web site. I have sniffed the data coming into my network and do see traffic (NetFlow) coming in from the correct src addy and UDP port. When it does trend and show on the web site, there are HUGE gaps (Hours, Days). SNMP and ICMP trending ok.
Orion 8.5.1, SP3, SQL2000 Std, NetFlow 2.2.1
I recommend opening a support case at http://www.solarwinds.com/support and ensure to include the Orion diagnostics, which can be created by executing SolarwindsDiagnostics.exe at C:\Program Files\Solarwinds\Orion.
