Hi slobodan.lakic@telegroup.ba ,
There is no problem with collecting flow of different versions from exporters. In the Stealthwatch Desktop Client, the NetFlow Collection Status table includes a column for "Flow Types" and will show you the version received from the exporter; NetFlow v9, NetFlow v5, IPFIX, etc.
If you're having problems with the v9 configuration, make sure you are collecting all of the requisite datapoints:
• Source IP
• Destination IP
• Source Port
• Destination Port
• IP Protocol
• Packet Count
• Byte Count
• Time first seen
• Time last seen
For reference, check the NetFlow Configuration Guide for your version of operating system.
