Netflow showing as unreachable in the CAPC system status. However everything NFA related works except system status. Port 8981 is open from CAPC to NFA unidirectional.
In this case there was a load balancer that the hostname for the VNA system passed through Causing the status check call to fail.
Release : 20.2
Component : PERFORMANCE MANAGEMENT INTEGRATIONS
We added the NFA IP/Hostname to /etc/hosts file so it would not go through the load balancer and now the status is green. Also configuring the data source with the direct IP and not hostname works.
