@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:30:36.874Z") @Stability(Stable) public class Metric extends implements IMetric
A metric emitted by a service.

The metric is a combination of a metric identifier (namespace, name and dimensions) and an aggregation function (statistic, period and unit).

It also contains metadata which is used only in graphs, such as color and label. It makes sense to embed this in here, so that compound constructs can attach that metadata to metrics they expose.

This class does not represent a resource, so hence is not a construct. Instead, Metric is an abstraction that makes it easy to specify metrics for use in both alarms and graphs.

    • Metric

      protected Metric( initializationMode)
    • Metric

      @Stability(Stable) public Metric(@NotNull MetricProps props)
      props - This parameter is required.
  • Method Details

    • grantPutMetricData

      @Stability(Stable) @NotNull public static Grant grantPutMetricData(@NotNull IGrantable grantee)
      Grant permissions to the given identity to write metrics.

      grantee - The IAM identity to give permissions to. This parameter is required.
    • attachTo

      @Stability(Stable) @NotNull public Metric attachTo(@NotNull software.constructs.IConstruct scope)
      Attach the metric object to the given construct scope.

      Returns a Metric object that uses the account and region from the Stack the given construct is defined in. If the metric is subsequently used in a Dashboard or Alarm in a different Stack defined in a different account or region, the appropriate 'region' and 'account' fields will be added to it.

      If the scope we attach to is in an environment-agnostic stack, nothing is done and the same Metric object is returned.

      scope - This parameter is required.
    • createAlarm

      @Stability(Stable) @NotNull public Alarm createAlarm(@NotNull Construct scope, @NotNull String id, @NotNull CreateAlarmOptions props)
      Make a new Alarm for this metric.

      Combines both properties that may adjust the metric (aggregation) as well as alarm properties.

      scope - This parameter is required.
      id - This parameter is required.
      props - This parameter is required.

    • toGraphConfig

      @Stability(Deprecated) @Deprecated @NotNull public MetricGraphConfig toGraphConfig()
      use toMetricConfig()
      (deprecated) Turn this metric object into a graph configuration.

      Specified by:
      toGraphConfig in interface IMetric
    • toMetricConfig

      @Stability(Stable) @NotNull public MetricConfig toMetricConfig()
      Inspect the details of the metric object.
      Specified by:
      toMetricConfig in interface IMetric
    • toString

      @Stability(Stable) @NotNull public String toString()

    • with

      @Stability(Stable) @NotNull public Metric with(@NotNull MetricOptions props)
      Return a copy of Metric with properties changed.

      All properties except namespace and metricName can be changed.

      props - The set of properties to change. This parameter is required.
