public enum Statistic
extends Enum<Statistic>

Statistic to use over the aggregation period.

Example:

 import software.amazon.awscdk.services.cloudwatch.*;
 DeliveryStream deliveryStream;
 // Alarm that triggers when the per-second average of incoming bytes exceeds 90% of the current service limit
 MathExpression incomingBytesPercentOfLimit = MathExpression.Builder.create()
         .expression("incomingBytes / 300 / bytePerSecLimit")
         .usingMetrics(Map.of(
                 "incomingBytes", deliveryStream.metricIncomingBytes(MetricOptions.builder().statistic(Statistic.SUM).build()),
                 "bytePerSecLimit", deliveryStream.metric("BytesPerSecondLimit")))
         .build();
 Alarm.Builder.create(this, "Alarm")
         .metric(incomingBytesPercentOfLimit)
         .threshold(0.9)
         .evaluationPeriods(3)
         .build();

Enum Constant Details

SAMPLE_COUNT

@Stability(Stable)
public static final Statistic SAMPLE_COUNT

The count (number) of data points used for the statistical calculation.

AVERAGE

@Stability(Stable)
public static final Statistic AVERAGE

The value of Sum / SampleCount during the specified period.

SUM

@Stability(Stable)
public static final Statistic SUM

All values submitted for the matching metric added together.

This statistic can be useful for determining the total volume of a metric.

MINIMUM

@Stability(Stable)
public static final Statistic MINIMUM

The lowest value observed during the specified period.

You can use this value to determine low volumes of activity for your application.

MAXIMUM

@Stability(Stable)
public static final Statistic MAXIMUM

The highest value observed during the specified period.

You can use this value to determine high volumes of activity for your application.

Method Details

values

public static Statistic[] values()

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

Returns:

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

valueOf

public static Statistic 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
