@Generated("software.amazon.awssdk:codegen")
public class CloudWatchAlarmDefinition
extends Object
implements StructuredPojo, ToCopyableBuilder<CloudWatchAlarmDefinition.Builder,CloudWatchAlarmDefinition>

The definition of a CloudWatch metric alarm, which determines when an automatic scaling activity is triggered. When the defined alarm conditions are satisfied, scaling activity begins.

Method Detail

comparisonOperator

public String comparisonOperator()

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

Returns:

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

ComparisonOperator

evaluationPeriods

public Integer evaluationPeriods()

The number of periods, expressed in seconds using Period, during which the alarm condition must exist before the alarm triggers automatic scaling activity. The default value is 1.

Returns:

The number of periods, expressed in seconds using Period, during which the alarm condition must exist before the alarm triggers automatic scaling activity. The default value is 1.

metricName

public String metricName()

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

Returns:

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

namespace

public String namespace()

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

Returns:

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

period

public Integer period()

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

Returns:

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

statistic

public String statistic()

The statistic to apply to the metric associated with the alarm. The default is AVERAGE.

Returns:

The statistic to apply to the metric associated with the alarm. The default is AVERAGE.

See Also:

Statistic

threshold

public Double threshold()

The value against which the specified statistic is compared.

Returns:

The value against which the specified statistic is compared.

unit

public String unit()

The unit of measure associated with the CloudWatch metric being watched. The value specified for Unit must correspond to the units specified in the CloudWatch metric.

Returns:

The unit of measure associated with the CloudWatch metric being watched. The value specified for Unit must correspond to the units specified in the CloudWatch metric.
