public void setMetricValue(Double metricValue) {
        this.metricValue = metricValue;
    }
<p>
The metric value to compare to <code>BreachThreshold</code>. This enables you to execute a policy of type
<code>StepScaling</code> and determine which step adjustment to use. For example, if the breach threshold is 50
and you want to use a step adjustment with a lower bound of 0 and an upper bound of 10, you can set the metric
value to 59.
</p>
<p>
If you specify a metric value that doesn't correspond to a step adjustment for the policy, the call returns an
error.
</p>
<p>
Required if the policy type is <code>StepScaling</code> and not supported otherwise.
