public enum ComparisonOperator
extends Enum<ComparisonOperator>

(experimental) Comparison operator for evaluating alarms.

Example:

 import software.amazon.awscdk.core.*;
 Alias alias;
 // or add alarms to an existing group
 Alias blueGreenAlias;
 Alarm alarm = Alarm.Builder.create(this, "Errors")
         .comparisonOperator(ComparisonOperator.GREATER_THAN_THRESHOLD)
         .threshold(1)
         .evaluationPeriods(1)
         .metric(alias.metricErrors())
         .build();
 LambdaDeploymentGroup deploymentGroup = LambdaDeploymentGroup.Builder.create(this, "BlueGreenDeployment")
         .alias(alias)
         .deploymentConfig(LambdaDeploymentConfig.LINEAR_10PERCENT_EVERY_1MINUTE)
         .alarms(List.of(alarm))
         .build();
 deploymentGroup.addAlarm(Alarm.Builder.create(this, "BlueGreenErrors")
         .comparisonOperator(ComparisonOperator.GREATER_THAN_THRESHOLD)
         .threshold(1)
         .evaluationPeriods(1)
         .metric(blueGreenAlias.metricErrors())
         .build());

GREATER_THAN_OR_EQUAL_TO_THRESHOLD

@Stability(value=Experimental)
public static final ComparisonOperator GREATER_THAN_OR_EQUAL_TO_THRESHOLD

(experimental) Specified statistic is greater than or equal to the threshold.

GREATER_THAN_THRESHOLD

@Stability(value=Experimental)
public static final ComparisonOperator GREATER_THAN_THRESHOLD

(experimental) Specified statistic is strictly greater than the threshold.

LESS_THAN_THRESHOLD

@Stability(value=Experimental)
public static final ComparisonOperator LESS_THAN_THRESHOLD

(experimental) Specified statistic is lower than or greater than the anomaly model band.

Used only for alarms based on anomaly detection models

GREATER_THAN_UPPER_THRESHOLD

@Stability(value=Experimental)
public static final ComparisonOperator GREATER_THAN_UPPER_THRESHOLD

(experimental) Specified statistic is greater than the anomaly model band.

Used only for alarms based on anomaly detection models

Method Detail

values

public static ComparisonOperator[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ComparisonOperator c : ComparisonOperator.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ComparisonOperator valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
