# TargetConfiguration
<a name="API_TargetConfiguration"></a>

Settings for a target-based scaling policy. A target-based policy tracks a particular fleet metric specifies a target value for the metric. As player usage changes, the policy triggers Amazon GameLift Servers to adjust capacity so that the metric returns to the target value. The target configuration specifies settings as needed for the target based policy, including the target value.

For example, in a policy using the metric PercentAvailableGameSessions, the target value should be the preferred size of the fleet's buffer (the percent of capacity that should be idle and ready for new game sessions).
