The name of the CloudWatch log group where evaluation results will be written. This value doesn't apply when `resultDestination` is `SOURCE_LOG_GROUP`, because results are written back to the trace source log group. The name can't be under the service-reserved `/aws/bedrock-agentcore/evaluations/` namespace, apart from the service-managed default group.
