Class MetricDimension

java.lang.Object

com.amazonaws.services.elasticmapreduce.model.MetricDimension

All Implemented Interfaces:

Serializable, Cloneable

public class MetricDimension
extends Object
implements Serializable, Cloneable

A CloudWatch dimension, which is specified using a Key (known as a Name in CloudWatch), Value pair. By default, Amazon EMR uses one dimension whose Key is JobFlowID and Value is a variable representing the cluster ID, which is ${emr:cluster_id}. This enables the rule to bootstrap when the cluster ID becomes available, and also enables a single automatic scaling policy to be reused for multiple clusters and instance groups.
