You can delete an element from the Inventory Explorer page. Deleting an element in CloudWisdom persists only until the next collection cycle unless the element is also no longer being collected or posting to CloudWisdom. The metadata for a deleted element is retained for 60 days. Stale metadata (old metrics no longer collecting, attributes and tags that no longer exist) gets permanently deleted. The band analytic history for metrics associated with the deleted element is retained for 90 days.
