On system status page the "Network Flow Analysis" section shows as "Failed" with the NFA data sources having status "Unreachable". 

Also configuration changes in NetOps Portal to the Harvester/Application settings in the NFA data source configuration page on the Netops Portal result in a 500 error when saved

Environment

NFA All Versions

 

Cause

-TCP port 8981 [NFA data read via OData API] needs to be open between CA PC / NetOps Portal and NFA console.

-Make sure "CA NFA Odata Service" is running on the NFA Console

 

 

 

Resolution

-TCP port 8981 [NFA data read via OData API] needs to be open between CA PC / CA NPC Console  and NFA console.

 

-Make sure "CA NFA Odata Service" is running on the NFA Console. Try restarting this service.

 

 

Port 8981 has to be open on the NFA console machine for communication to happen between NetOps Portal and NFA for NFA admin pages and SystemStatus.
