Contains customized metric specification information for a target tracking scaling policy for Amazon EC2 Auto Scaling.

To create your customized metric specification:

  • Add values for each required property 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.

For more information about CloudWatch, see Amazon CloudWatch Concepts .

CustomizedMetricSpecification is a property of the AWS::AutoScaling::ScalingPolicy TargetTrackingConfiguration property type.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_autoscaling as autoscaling } from 'aws-cdk-lib';
const customizedMetricSpecificationProperty: autoscaling.CfnScalingPolicy.CustomizedMetricSpecificationProperty = {
  metricName: 'metricName',
  namespace: 'namespace',
  statistic: 'statistic',

  // the properties below are optional
  dimensions: [{
    name: 'name',
    value: 'value',
  }],
  unit: 'unit',
};

Properties

NameTypeDescription
metricNamestringThe name of the metric.
namespacestringThe namespace of the metric.
statisticstringThe statistic of the metric.
dimensions?IResolvable | IResolvable | MetricDimensionProperty[]The dimensions of the metric.
unit?stringThe unit of the metric.

metricName

Type: string

The name of the metric.

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


namespace

Type: string

The namespace of the metric.


statistic

Type: string

The statistic of the metric.


dimensions?

Type: IResolvable | IResolvable | MetricDimensionProperty[] (optional)

The dimensions of the metric.

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


unit?

Type: string (optional)

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 .
