For more information, see Target tracking scaling policies in the Application Auto Scaling User Guide.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

target_value: f64

The target value for the metric. Although this property accepts numbers of type Double, it won't accept values that are either too small or too large. Values must be in the range of -2^360 to 2^360. The value must be a valid number based on the choice of metric. For example, if the metric is CPU utilization, then the target value is a percent value that represents how much of the CPU can be used before scaling out.

If the scaling policy specifies the ALBRequestCountPerTarget predefined metric, specify the target utilization as the optimal average request count per target during any one-minute interval.

predefined_metric_specification: Option<PredefinedMetricSpecification>

A predefined metric. You can specify either a predefined metric or a customized metric.

customized_metric_specification: Option<CustomizedMetricSpecification>

A customized metric. You can specify either a predefined metric or a customized metric.

scale_out_cooldown: Option<i32>

The amount of time, in seconds, to wait for a previous scale-out activity to take effect. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.

scale_in_cooldown: Option<i32>

The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.

disable_scale_in: Option<bool>

Indicates whether scale in by the target tracking scaling policy is disabled. If the value is true, scale in is disabled and the target tracking scaling policy won't remove capacity from the scalable target. Otherwise, scale in is enabled and the target tracking scaling policy can remove capacity from the scalable target. The default value is false.

Implementations

impl TargetTrackingScalingPolicyConfiguration

pub fn target_value(&self) -> f64

The target value for the metric. Although this property accepts numbers of type Double, it won't accept values that are either too small or too large. Values must be in the range of -2^360 to 2^360. The value must be a valid number based on the choice of metric. For example, if the metric is CPU utilization, then the target value is a percent value that represents how much of the CPU can be used before scaling out.

If the scaling policy specifies the ALBRequestCountPerTarget predefined metric, specify the target utilization as the optimal average request count per target during any one-minute interval.

pub fn predefined_metric_specification( &self ) -> Option<&PredefinedMetricSpecification>

A predefined metric. You can specify either a predefined metric or a customized metric.

pub fn customized_metric_specification( &self ) -> Option<&CustomizedMetricSpecification>

A customized metric. You can specify either a predefined metric or a customized metric.

pub fn scale_out_cooldown(&self) -> Option<i32>

The amount of time, in seconds, to wait for a previous scale-out activity to take effect. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.

pub fn scale_in_cooldown(&self) -> Option<i32>

The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.

pub fn disable_scale_in(&self) -> Option<bool>

Indicates whether scale in by the target tracking scaling policy is disabled. If the value is true, scale in is disabled and the target tracking scaling policy won't remove capacity from the scalable target. Otherwise, scale in is enabled and the target tracking scaling policy can remove capacity from the scalable target. The default value is false.

impl TargetTrackingScalingPolicyConfiguration

pub fn builder() -> TargetTrackingScalingPolicyConfigurationBuilder

Creates a new builder-style object to manufacture TargetTrackingScalingPolicyConfiguration.

Trait Implementations

impl Clone for TargetTrackingScalingPolicyConfiguration

fn clone(&self) -> TargetTrackingScalingPolicyConfiguration

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TargetTrackingScalingPolicyConfiguration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TargetTrackingScalingPolicyConfiguration

fn eq(&self, other: &TargetTrackingScalingPolicyConfiguration) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
