Method Detail

adjustmentType

public final AdjustmentType adjustmentType()

The way in which Amazon EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the Amazon EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of Amazon EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

If the service returns an enum value that is not available in the current SDK version, adjustmentType will return AdjustmentType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from adjustmentTypeAsString().

Returns:

The way in which Amazon EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the Amazon EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of Amazon EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

adjustmentTypeAsString

public final String adjustmentTypeAsString()

The way in which Amazon EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the Amazon EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as an integer.

scalingAdjustment

public final Integer scalingAdjustment()

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's Amazon EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.

Returns:

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's Amazon EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.

coolDown

public final Integer coolDown()

The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.

Returns:

The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.
