-
class
aws_cdk.aws_autoscaling.BasicTargetTrackingScalingPolicyProps(*, cooldown=None, disable_scale_in=None, estimated_instance_warmup=None, target_value, custom_metric=None, predefined_metric=None, resource_label=None)¶ Bases:
aws_cdk.aws_autoscaling.BaseTargetTrackingPropsProperties for a Target Tracking policy that include the metric but exclude the target.
- 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.target_value (
Union[int,float]) – The target value for the metric.custom_metric (
Optional[IMetric]) – A custom metric for application autoscaling. The metric must track utilization. Scaling out will happen if the metric is higher than the target value, scaling in will happen in the metric is lower than the target value. Exactly one of customMetric or predefinedMetric must be specified. Default: - No custom metric.predefined_metric (
Optional[PredefinedMetric]) – A predefined metric for application autoscaling. The metric must track utilization. Scaling out will happen if the metric is higher than the target value, scaling in will happen in the metric is lower than the target value. Exactly one of customMetric or predefinedMetric must be specified. Default: - No predefined metric.resource_label (
Optional[str]) – The resource label associated with the predefined metric. Should be supplied if the predefined metric is ALBRequestCountPerTarget, and the format should be: app///targetgroup// Default: - No resource label.
Attributes
-
cooldown¶ Period after a scaling completes before another scaling activity can start.
- Default
The default cooldown configured on the AutoScalingGroup.
- Return type
Optional[Duration]
-
custom_metric¶ A custom metric for application autoscaling.
The metric must track utilization. Scaling out will happen if the metric is higher than the target value, scaling in will happen in the metric is lower than the target value.
Exactly one of customMetric or predefinedMetric must be specified.
- Default
No custom metric.
- Return type
Optional[IMetric]
-
disable_scale_in¶ 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
false
- Return type
Optional[bool]
-
estimated_instance_warmup¶ Estimated time until a newly launched instance can send metrics to CloudWatch.
- Default
Same as the cooldown.
- Return type
Optional[Duration]
-
predefined_metric¶ A predefined metric for application autoscaling.
The metric must track utilization. Scaling out will happen if the metric is higher than the target value, scaling in will happen in the metric is lower than the target value.
Exactly one of customMetric or predefinedMetric must be specified.
- Default
No predefined metric.
- Return type
Optional[PredefinedMetric]
-
resource_label¶ The resource label associated with the predefined metric.
Should be supplied if the predefined metric is ALBRequestCountPerTarget, and the format should be:
app///targetgroup//
- Default
No resource label.
- Return type
Optional[str]
-
target_value¶ The target value for the metric.
- Return type
Union[int,float]
