Method Detail

metricSpecifications

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder metricSpecifications(IResolvable metricSpecifications)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getMetricSpecifications()

Parameters:

metricSpecifications - This structure includes the metrics and target utilization to use for predictive scaling. This parameter is required. This is an array, but we currently only support a single metric specification. That is, you can specify a target value and a single metric pair, or a target value and one scaling metric and one load metric.

Returns:

this

metricSpecifications

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder metricSpecifications(java.util.List<? extends java.lang.Object> metricSpecifications)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getMetricSpecifications()

Parameters:

metricSpecifications - This structure includes the metrics and target utilization to use for predictive scaling. This parameter is required. This is an array, but we currently only support a single metric specification. That is, you can specify a target value and a single metric pair, or a target value and one scaling metric and one load metric.

Returns:

this

maxCapacityBreachBehavior

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder maxCapacityBreachBehavior(java.lang.String maxCapacityBreachBehavior)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getMaxCapacityBreachBehavior()

Parameters:

maxCapacityBreachBehavior - Defines the behavior that should be applied if the forecast capacity approaches or exceeds the maximum capacity of the Auto Scaling group. Defaults to HonorMaxCapacity if not specified.

The following are possible values:

• HonorMaxCapacity - Amazon EC2 Auto Scaling cannot scale out capacity higher than the maximum capacity. The maximum capacity is enforced as a hard limit.
• IncreaseMaxCapacity - Amazon EC2 Auto Scaling can scale out capacity higher than the maximum capacity when the forecast capacity is close to or exceeds the maximum capacity. The upper limit is determined by the forecasted capacity and the value for MaxCapacityBuffer .

Returns:

this

maxCapacityBuffer

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder maxCapacityBuffer(java.lang.Number maxCapacityBuffer)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getMaxCapacityBuffer()

Parameters:

maxCapacityBuffer - The size of the capacity buffer to use when the forecast capacity is close to or exceeds the maximum capacity. The value is specified as a percentage relative to the forecast capacity. For example, if the buffer is 10, this means a 10 percent buffer, such that if the forecast capacity is 50, and the maximum capacity is 40, then the effective maximum capacity is 55.

If set to 0, Amazon EC2 Auto Scaling may scale capacity higher than the maximum capacity to equal but not exceed forecast capacity.

Required if the MaxCapacityBreachBehavior property is set to IncreaseMaxCapacity , and cannot be used otherwise.

Returns:

this

mode

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder mode(java.lang.String mode)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getMode()

Parameters:

mode - The predictive scaling mode. Defaults to ForecastOnly if not specified.

Returns:

this

schedulingBufferTime

public CfnScalingPolicy.PredictiveScalingConfigurationProperty.Builder schedulingBufferTime(java.lang.Number schedulingBufferTime)

Sets the value of CfnScalingPolicy.PredictiveScalingConfigurationProperty.getSchedulingBufferTime()

Parameters:

schedulingBufferTime - The amount of time, in seconds, by which the instance launch time can be advanced. For example, the forecast says to add capacity at 10:00 AM, and you choose to pre-launch instances by 5 minutes. In that case, the instances will be launched at 9:55 AM. The intention is to give resources time to be provisioned. It can take a few minutes to launch an EC2 instance. The actual amount of time required depends on several factors, such as the size of the instance and whether there are startup scripts to complete.

The value must be less than the forecast interval duration of 3600 seconds (60 minutes). Defaults to 300 seconds if not specified.

Returns:

this

build

public CfnScalingPolicy.PredictiveScalingConfigurationProperty build()

Builds the configured instance.

Returns:

a new instance of CfnScalingPolicy.PredictiveScalingConfigurationProperty

Throws:

java.lang.NullPointerException - if any required attribute was not provided
