Overview

Note:

When passing CustomizedMetricSpecification as input to an Aws::Client method, you can use a vanilla Hash:

{
  metric_name: "MetricName", # required
  namespace: "MetricNamespace", # required
  dimensions: [
    {
      name: "MetricDimensionName", # required
      value: "MetricDimensionValue", # required
    },
  ],
  statistic: "Average", # required, accepts Average, Minimum, Maximum, SampleCount, Sum
  unit: "MetricUnit",
}

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 AWS 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 CloudWatch, see Amazon CloudWatch Concepts.
