I can't see flow data in the Flow Statistics dashboard. I am not getting any NFA data in my dashboard, the dashboard screen is blank:
This is actually a dashboard that is NOT used for DX NetOps Network Flow Analysis or NFA, but for a different product called "Netops Flow".
The NetOps Flow dashboards capture flow data using the Internet Protocol Flow Information Export (IPFIX) protocol. NetOps Flow stores data alongside performance data, allowing you to combine performance and flow in custom charts.
For more information on NetOps Flow, please have a look here:

To use the NFA tool, please go to Performance > Infrastructure Health > Network Interface Performance, and here you will find the dashboard used for NFA Flow Data.
