I've received notifications in Orion that our company has nbar2 capable devices which are not sending nbar2 data. I was tasked with testing this out to see if we like it better than netflow. I have the flow record, monitor and exporter configured how the solarwinds documentation shows but I don't see the data coming into Orion.
How do I choose the source interface for the exporter? Is this the LAN or WAN interface?
Which interfaces do I apply the flow monitor? WAN only?
