Overview

Note:

When passing TargetTrackingConfiguration as input to an Aws::Client method, you can use a vanilla Hash:

{
  predefined_scaling_metric_specification: {
    predefined_scaling_metric_type: "ASGAverageCPUUtilization", # required, accepts ASGAverageCPUUtilization, ASGAverageNetworkIn, ASGAverageNetworkOut, DynamoDBReadCapacityUtilization, DynamoDBWriteCapacityUtilization, ECSServiceAverageCPUUtilization, ECSServiceAverageMemoryUtilization, ALBRequestCountPerTarget, RDSReaderAverageCPUUtilization, RDSReaderAverageDatabaseConnections, EC2SpotFleetRequestAverageCPUUtilization, EC2SpotFleetRequestAverageNetworkIn, EC2SpotFleetRequestAverageNetworkOut
    resource_label: "ResourceLabel",
  },
  customized_scaling_metric_specification: {
    metric_name: "MetricName", # required
    namespace: "MetricNamespace", # required
    dimensions: [
      {
        name: "MetricDimensionName", # required
        value: "MetricDimensionValue", # required
      },
    ],
    statistic: "Average", # required, accepts Average, Minimum, Maximum, SampleCount, Sum
    unit: "MetricUnit",
  },
  target_value: 1.0, # required
  disable_scale_in: false,
  scale_out_cooldown: 1,
  scale_in_cooldown: 1,
  estimated_instance_warmup: 1,
}

Represents a target tracking scaling policy.

Instance Attribute Details

#customized_scaling_metric_specificationTypes::CustomizedScalingMetricSpecification

A customized metric.

Returns:

#disable_scale_inBoolean

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 scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false.

Returns:

  • (Boolean)

    Indicates whether scale in by the target tracking policy is disabled.

#estimated_instance_warmupInteger

The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This value is used only if the resource is an Auto Scaling group.

Returns:

  • (Integer)

    The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics.

#predefined_scaling_metric_specificationTypes::PredefinedScalingMetricSpecification

A predefined metric.

Returns:

#scale_in_cooldownInteger

The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. This value is not used if the scalable resource is an Auto Scaling group.

The cooldown period is used to block subsequent scale in requests until it has expired. The intention is to scale in conservatively to protect your application\'s availability. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, AWS Auto Scaling scales out your scalable target immediately.

Returns:

  • (Integer)

    The amount of time, in seconds, after a scale in activity completes before another scale in activity can start.

#scale_out_cooldownInteger

The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. This value is not used if the scalable resource is an Auto Scaling group.

While the cooldown period is in effect, the capacity that has been added by the previous scale out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. The intention is to continuously (but not excessively) scale out.

Returns:

  • (Integer)

    The amount of time, in seconds, after a scale out activity completes before another scale out activity can start.

#target_valueFloat

The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

Returns:

  • (Float)

    The target value for the metric.
