The Aria Operations plugin for vSphere is configured in vSphere but the link to Aria Operations shows the IP for that instance, not the FQDN
Aria Operations 8.18.0
vSphere 8.0.3
The Aria Operations plugin for vSphere does not support DNS.
There is no resolution for this at the moment.
The IP used in vSphere will equal the IP of the collector where the vSphere adapter is configured in Aria Operations. This includes if you use a Cloud Proxy to collect.
