val comparisonOperator: ComparisonOperator?

Determines how the metric specified by MetricName is compared to the value specified by Threshold.

dimensions

val dimensions: List<MetricDimension>?

A CloudWatch metric dimension.

evaluationPeriods

val evaluationPeriods: Int?

The number of periods, in five-minute increments, during which the alarm condition must exist before the alarm triggers automatic scaling activity. The default value is 1.

metricName

val metricName: String?

The name of the CloudWatch metric that is watched to determine an alarm condition.

namespace

val namespace: String?

The namespace for the CloudWatch metric. The default is AWS/ElasticMapReduce.

period

val period: Int?

The period, in seconds, over which the statistic is applied. CloudWatch metrics for Amazon EMR are emitted every five minutes (300 seconds), so if you specify a CloudWatch metric, specify 300.
