NetFlow Collector NetFlow Ingestion Count Increase Check
-----------------------------------------------------------

This procedure displays the output from the DS9 Collector
NetFlow Count indicator via the CLI **Administration** menu. 

A count
increase when comparing 2 count values generated in succession validates
that all NetFlow ingestion and parsing services and processes are functioning properly, 
and that the database is functioning properly.

If the netflow count displays a value of **0** and the Health Check is
showing **SUCCESS**, the system might not be receiving flow from the
systems configured to send flow to the DS9. Validate that there are no
firewalls impeding the netflow traffic to the DS9 before contacting VOSS
support.

8. View the NetFlow data count number, which displays for the second time. 

   The count number displays a larger number compared to the first count display. This 
   count increase is validation that the incoming NetFlow packets are being ingested into the 
   database and that the system processes are working properly.
