If you select Visibility as your Monitoring option (in the Monitoring Options section of the Azure Setup page), when you run Discovery, Cloud Discovery & Visibility (CDV) creates visibility jobs to monitor the status of discovered resources. On an Azure infraststructure, these jobs are organized into Visibility Managers: An abstracted layer to simplify your management of Azure visibility jobs.
A Visibility Manager contains one or more Visibility jobs. When managing execution of visibility jobs in the Visibility Management page, you perform actions on the Visibility Manager instead of a specific job. CDV then performs that action on all jobs within that Visibility Manager.
The jobs that a Visibility Manager contains depend on the subscription and/or resource groups that you specify in the Azure Credentials page:
Discovery of a specific subscription with a specific resource group: CDV will create a single Visibility Manager that contains a single Visibility job.
Discovery of a specific subscription with all resource groups: CDV will create a single Visibility Manager that contains multiple Visibility jobs — a single Visibility job for each resource group.
Discovery of all subscriptions with all resource groups: CDV will create a single Visibility Manager that contains multiple Visibility jobs — a single Visibility job for each resource group within each subscription.
