extends software.amazon.jsii.JsiiSerializable
The conditions that trigger an automatic scaling activity and the definition of a CloudWatch metric alarm.
When the defined alarm conditions are met along with other trigger parameters, scaling activity begins.
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.*; import software.amazon.awscdk.services.stepfunctions.tasks.*; ScalingTriggerProperty scalingTriggerProperty = ScalingTriggerProperty.builder() .cloudWatchAlarmDefinition(CloudWatchAlarmDefinitionProperty.builder() .comparisonOperator(EmrCreateCluster.getCloudWatchAlarmComparisonOperator().GREATER_THAN_OR_EQUAL) .metricName("metricName") .period(Duration.minutes(30)) // the properties below are optional .dimensions(List.of(MetricDimensionProperty.builder() .key("key") .value("value") .build())) .evaluationPeriods(123) .namespace("namespace") .statistic(EmrCreateCluster.getCloudWatchAlarmStatistic().SAMPLE_COUNT) .threshold(123) .unit(EmrCreateCluster.getCloudWatchAlarmUnit().NONE) .build()) .build();
