I upgraded to 8.5 yesterday from 8.0, and went from netflow 2.0 to 2.2. I've had nothing but issues since. My first issue is that my network maps no longer show up properly. Before the upgrade, I had a map of the US with lines and embedded maps. The only thing I can see now is a big gray box with my lines and a few labels. I pull up the map in mapmaker and everything looks great. I tried modifying the view by re-adding the map, creating a fresh map, and changing to an existing map. Nothing works, I can only see the big gray box of nothing. I opened a ticket with support, but no solutions yet.
The other issue I am having is with netflow. If I click on a node on my website that has a neflow data because netflow is enabled on it, the node details come up fine. If i click on anything else, like a server, that obviously doesn't have netflow data, i get a nasty error message listed below. I should have waited awhile before i upgraded.
