MetricDatum class

Encapsulates the information sent to either create a metric or add new values to be aggregated into an existing metric.

Constructors

MetricDatum({required String metricName, List<double>? counts, List<Dimension>? dimensions, StatisticSet? statisticValues, int? storageResolution, DateTime? timestamp, StandardUnit? unit, double? value, List<double>? values})

Properties

counts → List<double>?

Array of numbers that is used along with the Values array. Each number in the Count array is the number of times the corresponding value in the Values array occurred during the period.

final

dimensions → List<Dimension>?

The dimensions associated with the metric.

final

hashCode → int

The hash code for this object.

no setter, inherited

metricName → String

The name of the metric.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

statisticValues → StatisticSet?

The statistical values for the metric.

final

storageResolution → int?

Valid values are 1 and 60. Setting this to 1 specifies this metric as a high-resolution metric, so that CloudWatch stores the metric with sub-minute resolution down to one second. Setting this to 60 specifies this metric as a regular-resolution metric, which CloudWatch stores at 1-minute resolution. Currently, high resolution is available only for custom metrics. For more information about high-resolution metrics, see High-Resolution Metrics in the Amazon CloudWatch User Guide.

final

timestamp → DateTime?

The time the metric data was received, expressed as the number of milliseconds since Jan 1, 1970 00:00:00 UTC.

final

unit → StandardUnit?

When you are using a Put operation, this defines what unit you want to use when storing the metric.

final

value → double?

The value for the metric.

final

values → List<double>?

Array of numbers representing the values for the metric during the period. Each unique value is listed just once in this array, and the corresponding number in the Counts array specifies the number of times that value occurred during the period. You can include up to 150 unique values in each PutMetricData action that specifies a Values array.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
