utilizationTarget property
The target value of the metric that autoscaler maintains. This must be a positive value. A utilization metric scales number of virtual machines handling requests to increase or decrease proportionally to the metric.
For example, a good metric to use as a utilization_target ishttps://www.googleapis.com/compute/v1/instance/network/received_bytes_count. The autoscaler works to keep this value constant for each of the instances.
Implementation
final double? utilizationTarget;
