/**
 * <p>
 * Represents a CloudWatch metric of your choosing that can be used for dynamic scaling as part of a target tracking

 * </p>
 * <p>
 * To create your customized scaling metric specification:
 * </p>
 * <ul>
 * <li>
 * <p>
 * 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 <a
 * href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html">Publish Custom
 * Metrics</a> in the <i>Amazon CloudWatch User Guide</i>.
 * </p>
 * </li>
 * <li>
 * <p>
 * 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.
