RequestCountScalingProps

class aws_cdk.aws_autoscaling.RequestCountScalingProps(*, cooldown=None, disable_scale_in=None, estimated_instance_warmup=None, target_requests_per_minute=None, target_requests_per_second=None)

Bases: aws_cdk.aws_autoscaling.BaseTargetTrackingProps

Properties for enabling scaling based on request/second.

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: false

  • estimated_instance_warmup (Optional[Duration]) – Estimated time until a newly launched instance can send metrics to CloudWatch. Default: - Same as the cooldown.

  • target_requests_per_minute (Union[int, float, None]) – Target average requests/minute on each instance. Default: - Specify exactly one of ‘targetRequestsPerMinute’ and ‘targetRequestsPerSecond’

  • target_requests_per_second (Union[int, float, None]) – (deprecated) Target average requests/seconds on each instance. Default: - Specify exactly one of ‘targetRequestsPerMinute’ and ‘targetRequestsPerSecond’
