Represents the properties of a target tracking scaling policy.

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.

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

scale_in_cooldown: Option<i32>

The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. The cooldown period is used to block subsequent scale in requests until it has expired. You should 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, application auto scaling scales out your scalable target immediately.

scale_out_cooldown: Option<i32>

The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. 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. You should continuously (but not excessively) scale out.

target_value: f64

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).

Implementations

impl AutoScalingTargetTrackingScalingPolicyConfigurationDescription

pub fn disable_scale_in(&self) -> Option<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 scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false.

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. The cooldown period is used to block subsequent scale in requests until it has expired. You should 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, application auto scaling scales out your scalable target immediately.

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

The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. 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. You should continuously (but not excessively) scale out.

pub fn target_value(&self) -> f64

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).

impl AutoScalingTargetTrackingScalingPolicyConfigurationDescription

pub fn builder() -> AutoScalingTargetTrackingScalingPolicyConfigurationDescriptionBuilder

Creates a new builder-style object to manufacture AutoScalingTargetTrackingScalingPolicyConfigurationDescription.

Trait Implementations

impl Clone for AutoScalingTargetTrackingScalingPolicyConfigurationDescription

fn clone( &self, ) -> AutoScalingTargetTrackingScalingPolicyConfigurationDescription

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AutoScalingTargetTrackingScalingPolicyConfigurationDescription

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

Formats the value using the given formatter.

impl PartialEq for AutoScalingTargetTrackingScalingPolicyConfigurationDescription

fn eq( &self, other: &AutoScalingTargetTrackingScalingPolicyConfigurationDescription, ) -> 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.
