Currently, we do not have any API to pull data directly from the database for NFA/RA.
If you are familiar querying mysql you can can query the database yourself with select
queries, but unfortunately we do not publish a full schema for the database.
If you want to view the raw NetFlow data, it is not a straight forward query, you are
better off using the "Flow Forensics" reports which can report on the last 24 hours of
Raw unfiltered NetFlow data.
If you would like to see an enhancement you can go to the following link up vote on
the idea already submitted.
