listDiscoveredResources

Returns a list of resource resource identifiers for the specified resource types for the resources of that type. A resource identifier includes the resource type, ID, and (if available) the custom resource name.

The results consist of resources that Config has discovered, including those that Config is not currently recording. You can narrow the results to include only resources that have specific resource IDs or a resource name.

You can specify either resource IDs or a resource name, but not both, in the same request.

CloudFormation stack recording behavior in Config

When a CloudFormation stack fails to create (for example, it enters the ROLLBACK_FAILED state), Config does not record a configuration item (CI) for that stack. Configuration items are only recorded for stacks that reach the following states:

• CREATE_COMPLETE

• UPDATE_COMPLETE

• UPDATE_ROLLBACK_COMPLETE

• UPDATE_ROLLBACK_FAILED

• DELETE_FAILED

• DELETE_COMPLETE Because no CI is created for a failed stack creation, you won't see configuration history for that stack in Config, even after the stack is deleted. This helps make sure that Config only tracks resources that were successfully provisioned.
