Cloud Discovery & Visibility (CDV) lets you update, delete, and import new cloud resources based on discovery tasks you ran before (even if you can't run visibility tasks on your cloud infrastructure).
The process of rerunning discovery tasks on the same configuration is referred to as rediscovery. During rediscovery, CDV does the following:
-
CDV adds cloud resources that are new to Address Manager since the last discovery task was run.
-
CDV updates resources that were discovered in previous runs (and that exist in Address Manager), but that have changed.
-
CDV tags resources that currently discovered in previous runs and that exist in Address Manager, but that were removed since the previous discovery task. You can view those resources in the Deleted Tagged Resources tab.
Tip: If you prefer, you can tell CDV to automatically delete those resources when configuring the rediscovery task. To do so, select the Remove Deleted Resources during rediscovery checkbox.
When performing a rediscovery, CDV updates resources in Address Manager for each platform based on the following types of changes.
- VPC/Subnets
- Creating a new VPC/Subnet
- Updating a CIDR of a VPC/Subnet
