I performed a new installation of UIM and I deployed several components: 1 oc server, 1 primary hub, 1 bd server and a secondary hub that I am going to use for monitoring by icmp, after configuring the secondary hub it does not report on the domain from UIM, however, I do a test by logging into IM and I see that the probes were deployed correctly, including the hub probe, but I still don't see it in the UIM domain as a secondary hub.
Check the hub.cfg to make sure its configured as expected, and if it is actually correct, then try adding the Secondary hub to the hub 'Name Services' as a Static hub.
Adding the Secondary hub to the hub 'Name Services' as a Static hub resolved the issue.
