While setting up a discovery, you can set the Monitoring mode to Scheduled updates. Doing so creates a schedule manager with discovery jobs that can be re-run to update the list of resources imported to Address Manager. Re-running the discovery updates, deletes, and imports new cloud resources.
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.
-
(Applies only if the Remove deleted resources during rediscovery is enabled in the Discovery options) CDV keeps track of resources in BlueCat Address Manager that were removed from the cloud environment but not removed from Address Manager. To do so, CDV "tags" them so that they can be removed manually by the user later. Resources in Address Manager that are tagged by CDV are Configurations (including overlapping network configurations), Views, and Zones that were discovered in previous discoveries and that exist in Address Manager, but that no longer exist in the cloud when the last discovery was run. You can view tagged Configurations, Views, and Zones in the Tagged resources tab and remove them manually from there.
Resources other than the ones mentioned above are removed, except for child resources with a parent resource that is tagged for deletion. Those child resources will be removed when you manually delete the parent resource from the Tagged Resources tab.
Note: If Remove deleted resources during discovery is cleared, CDV will not delete or tag any resources that were removed from the cloud.
