Struct aws_sdk_applicationautoscaling::types::PredefinedMetricSpecification

#[non_exhaustive]
pub struct PredefinedMetricSpecification {
    pub predefined_metric_type: MetricType,
    pub resource_label: Option<String>,
}

Represents a predefined metric for a target tracking scaling policy to use with Application Auto Scaling.

Only the Amazon Web Services that you're using send metrics to Amazon CloudWatch. To determine whether a desired metric already exists by looking up its namespace and dimension using the CloudWatch metrics dashboard in the console, follow the procedure in Monitor your resources using CloudWatch 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.

predefined_metric_type: MetricType

The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleets and ECS services.

resource_label: Option<String>

Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet or ECS service.

You create the resource label by appending the final portion of the load balancer ARN and the final portion of the target group ARN into a single value, separated by a forward slash (/). The format of the resource label is:

app/my-alb/778d41231b141a0f/targetgroup/my-alb-target-group/943f017f100becff.

Where:

• app/ / is the final portion of the load balancer ARN

• targetgroup/ / is the final portion of the target group ARN.

To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

Implementations

impl PredefinedMetricSpecification

pub fn predefined_metric_type(&self) -> &MetricType

The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleets and ECS services.

pub fn resource_label(&self) -> Option<&str>

Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet or ECS service.

You create the resource label by appending the final portion of the load balancer ARN and the final portion of the target group ARN into a single value, separated by a forward slash (/). The format of the resource label is:

app/my-alb/778d41231b141a0f/targetgroup/my-alb-target-group/943f017f100becff.

Where:

• app/ / is the final portion of the load balancer ARN

• targetgroup/ / is the final portion of the target group ARN.

To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

impl PredefinedMetricSpecification

pub fn builder() -> PredefinedMetricSpecificationBuilder

Creates a new builder-style object to manufacture PredefinedMetricSpecification.

Trait Implementations

impl Clone for PredefinedMetricSpecification

fn clone(&self) -> PredefinedMetricSpecification

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredefinedMetricSpecification

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

Formats the value using the given formatter.

impl PartialEq for PredefinedMetricSpecification

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