Struct TargetTrackingConfiguration

pub struct TargetTrackingConfiguration {
    pub predefined_metric_specification: Option<PredefinedMetricSpecification>,

Represents a target tracking scaling policy configuration to use with Amazon EC2 Auto Scaling.

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.

predefined_metric_specification: Option<PredefinedMetricSpecification>

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

customized_metric_specification: Option<CustomizedMetricSpecification>

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

target_value: Option<f64>

The target value for the metric.

Some metrics are based on a count instead of a percentage, such as the request count for an Application Load Balancer or the number of messages in an SQS queue. If the scaling policy specifies one of these metrics, specify the target utilization as the optimal average request or message count per instance during any one-minute interval.

disable_scale_in: Option<bool>

Indicates whether scaling in by the target tracking scaling policy is disabled. If scaling in is disabled, the target tracking scaling policy doesn't remove instances from the Auto Scaling group. Otherwise, the target tracking scaling policy can remove instances from the Auto Scaling group. The default is false.

Implementations

impl TargetTrackingConfiguration

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

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

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

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

pub fn target_value(&self) -> Option<f64>

The target value for the metric.

Some metrics are based on a count instead of a percentage, such as the request count for an Application Load Balancer or the number of messages in an SQS queue. If the scaling policy specifies one of these metrics, specify the target utilization as the optimal average request or message count per instance during any one-minute interval.

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

Indicates whether scaling in by the target tracking scaling policy is disabled. If scaling in is disabled, the target tracking scaling policy doesn't remove instances from the Auto Scaling group. Otherwise, the target tracking scaling policy can remove instances from the Auto Scaling group. The default is false.

impl TargetTrackingConfiguration

pub fn builder() -> TargetTrackingConfigurationBuilder

Creates a new builder-style object to manufacture TargetTrackingConfiguration.

Trait Implementations

impl Clone for TargetTrackingConfiguration

fn clone(&self) -> TargetTrackingConfiguration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetTrackingConfiguration

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

Formats the value using the given formatter.

impl PartialEq for TargetTrackingConfiguration

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

Tests for self and other values to be equal, and is used by ==.

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

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