class
aws_cdk.aws_autoscaling.MetricTargetTrackingProps(*, cooldown=None, disable_scale_in=None, estimated_instance_warmup=None, metric, target_value)¶ Bases:
aws_cdk.aws_autoscaling.BaseTargetTrackingProps-
__init__(*, cooldown=None, disable_scale_in=None, estimated_instance_warmup=None, metric, target_value)¶ Properties for enabling tracking of an arbitrary metric.
- Parameters
cooldown (
Optional[Duration]) – Period after a scaling completes before another scaling activity can start. Default: - The default cooldown configured on the AutoScalingGroup.disable_scale_in (
Optional[bool]) – Indicates whether scale in by the target tracking policy is disabled. If the value is true, scale in is disabled and the target tracking policy won’t remove capacity from the autoscaling group. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the group. Default: falseestimated_instance_warmup (
Optional[Duration]) – Estimated time until a newly launched instance can send metrics to CloudWatch. Default: - Same as the cooldown.metric (
IMetric) – Metric to track. The metric must represent a utilization, so that if it’s higher than the target value, your ASG should scale out, and if it’s lower it should scale in.target_value (
Union[int,float]) – Value to keep the metric around.
