<p>
The target value for the metric.

<note>
<p>
Some metrics are based on a count instead of a percentage, such as the request count for an Application Load
Balancer or the number of messages in an SQS queue. If the scaling policy specifies one of these metrics, specify
the target utilization as the optimal average request or message count per instance during any one-minute
interval.
