I'm slightly puzzled by the fact only one Web Adaptor is showing as registered in Portal, even though I have two registered and functioning. Is this normal behaviour?
Home > System > Web Adaptors API Reference
Supported Interfaces: REST
We have Windows 2016/IIS10 set up a Portal for ArcGIS 10.6.1 HA Base pair, IIS Web Adaptor 10.6.1 built using Chef, sat behind a reverse proxy and configured with the Web Conext for the LB set up. Both WA's are configured and registered and the HA has been tested by turning off individual App Pools to ensure the LB is diverting traffic to the active WA/Portal node.
Everything is working as designed but I don't like the fact the second WA is not showing within \portaladmin. This seems odd behaviour vs what you see within ArcGIS Server??
Any advise would be greatly appreciated.
