public PredefinedMetricSpecification withResourceLabel(String resourceLabel) {

<p>
A label that uniquely identifies a specific Application Load Balancer target group from which to determine the
average request count served by your Auto Scaling group. You can't specify a resource label unless the target
group is attached to the Auto Scaling group.
</p>
<p>
You create the resource label by appending the final portion of the load balancer ARN and the final portion of
the target group ARN into a single value, separated by a forward slash (/). The format of the resource label is:
</p>
<p>
<code>app/my-alb/778d41231b141a0f/targetgroup/my-alb-target-group/943f017f100becff</code>.
</p>
<p>
Where:
</p>
<ul>
<li>
<p>
app/&lt;load-balancer-name&gt;/&lt;load-balancer-id&gt; is the final portion of the load balancer ARN
</p>
</li>
<li>
<p>
targetgroup/&lt;target-group-name&gt;/&lt;target-group-id&gt; is the final portion of the target group ARN.
</p>
</li>
</ul>
