Struct CustomizedMetricSpecification 

#[non_exhaustive]
pub struct CustomizedMetricSpecification {
    pub metric_name: Option<String>,
    pub namespace: Option<String>,
    pub dimensions: Option<Vec<MetricDimension>>,
    pub statistic: Option<MetricStatistic>,
    pub unit: Option<String>,
    pub metrics: Option<Vec<TargetTrackingMetricDataQuery>>,
}

Represents a CloudWatch metric of your choosing for a target tracking scaling policy to use with Application Auto Scaling.

For information about the available metrics for a service, see Amazon Web Services services that publish CloudWatch metrics in the Amazon CloudWatch User Guide.

To create your customized metric specification:

• Add values for each required parameter from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish custom metrics in the Amazon CloudWatch User Guide.

• Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases, and increase when capacity decreases.

For more information about the CloudWatch terminology below, see Amazon CloudWatch concepts in the Amazon CloudWatch 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.

metric_name: Option<String>

The name of the metric. To get the exact metric name, namespace, and dimensions, inspect the Metric object that's returned by a call to ListMetrics.

namespace: Option<String>

The namespace of the metric.

dimensions: Option<Vec<MetricDimension>>

The dimensions of the metric.

Conditional: If you published your metric with dimensions, you must specify the same dimensions in your scaling policy.

statistic: Option<MetricStatistic>

The statistic of the metric.

unit: Option<String>

The unit of the metric. For a complete list of the units that CloudWatch supports, see the MetricDatum data type in the Amazon CloudWatch API Reference.

metrics: Option<Vec<TargetTrackingMetricDataQuery>>

The metrics to include in the target tracking scaling policy, as a metric data query. This can include both raw metric and metric math expressions.

Implementations

impl CustomizedMetricSpecification

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

The name of the metric. To get the exact metric name, namespace, and dimensions, inspect the Metric object that's returned by a call to ListMetrics.

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

The namespace of the metric.

pub fn dimensions(&self) -> &[MetricDimension]

The dimensions of the metric.

Conditional: If you published your metric with dimensions, you must specify the same dimensions in your scaling policy.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .dimensions.is_none().

pub fn statistic(&self) -> Option<&MetricStatistic>

The statistic of the metric.

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

The unit of the metric. For a complete list of the units that CloudWatch supports, see the MetricDatum data type in the Amazon CloudWatch API Reference.

pub fn metrics(&self) -> &[TargetTrackingMetricDataQuery]

The metrics to include in the target tracking scaling policy, as a metric data query. This can include both raw metric and metric math expressions.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .metrics.is_none().

impl CustomizedMetricSpecification

pub fn builder() -> CustomizedMetricSpecificationBuilder

Creates a new builder-style object to manufacture CustomizedMetricSpecification.

Trait Implementations

impl Clone for CustomizedMetricSpecification

fn clone(&self) -> CustomizedMetricSpecification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomizedMetricSpecification

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

Formats the value using the given formatter.

impl PartialEq for CustomizedMetricSpecification

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