MetricDimension is a subproperty of the CloudWatchAlarmDefinition property type.
MetricDimension specifies a CloudWatch dimension, which is specified with a Key Value pair. The key is known as a Name in CloudWatch. By default, Amazon EMR uses one dimension whose Key is JobFlowID and Value is a variable representing the cluster ID, which is ${emr.clusterId} . This enables the automatic scaling rule for EMR to bootstrap when the cluster ID becomes available during cluster creation.
Example
// The code below shows an example of how to instantiate this type.

key: 'key',
value: 'value',
};
