We are getting primary hub name in the SOI alerts which are coming from Nimsoft.
Release : 4.2
Component : SOI MANAGER
1) When a CI does not exist for an alert, then the CI maps to the primary hub. To avoid mapping of CIs to the primary hub, you can create ComputerSystem CIs based on the hostname property of the alarm. The process of creating CIs based on the hostname of the alarm is known as dynamic CI

2) By default UIM connector is mapped with "GenericIPDevice, ComputerSystem, HypervisorManager, Switch, MediaDrive, Application, File and Database" classes, if you haven't configured vmware, then you need to update the configuration file as documented below
