HA probe configured but does not connect to spooler

DX Unified Infrastructure Management (Nimsoft / UIM) NIMSOFT PROBES



I see the following output in the probe GUI when trying to setup the HA probe

<Please see attached file for image>

User-added image

The HA hub and  main hub are both tunnel servers connected via a common tunnel client.


Since the two hubs have a common hub on your tunnel client, and they communicate with that hub via a tunnel, the HA probe will not work. The two hubs that you wish to set up in an HA configuration must be attachable at least by name services.

Additional Information:

The HA probe is designed as a hot-standby system, where a hub will take over all workings (including robots) for a system that goes down.  It is not intended as a load balancing solution.
