createResourceMetricsConfiguration

Creates a resource metrics configuration for an Amazon Web Services resource. After you create a configuration, Amazon CloudWatch collects detailed metrics for that resource.

Each Amazon Web Services resource can have only one resource metrics configuration. If a configuration already exists for the specified resource ARN, this operation returns a ConflictException. To modify an existing configuration, use UpdateResourceMetricsConfiguration.

If the Amazon Web Services resource that you specify in ResourceArn does not exist, this operation returns a ResourceNotFoundException. Verify that the resource ARN is correct and that the resource exists before you retry the request.

To create a resource metrics configuration, you must have the cloudwatch:CreateResourceMetricsConfiguration permission. For information about scoping this permission to specific resources, see Condition keys for resource metrics configuration access in the Amazon CloudWatch User Guide.
