Translations with OpenTelemetry 0.7.0 format in CloudWatch

CloudWatch performs some transformations to put CloudWatch data into OpenTelemetry format.

Translating namespace, metric name, and dimensions

These attributes are key-value pairs encoded in the mapping.

  • One pair contains the namespace of the metric

  • One pair contains the name of the metric

  • For each dimension, CloudWatch stores the following pair: metricDatum.Dimensions[i].Name, metricDatum.Dimensions[i].Value

Translating Average, Sum, SampleCount, Min and Max

The Summary datapoint enables CloudWatch to export all of these statistics using one datapoint.

  • startTimeUnixNano contains the CloudWatch startTime

  • timeUnixNano contains the CloudWatch endTime

  • sum contains the Sum statistic.

  • count contains the SampleCount statistic.

  • quantile_values contains two valueAtQuantile.value objects:

    • valueAtQuantile.quantile = 0.0 with valueAtQuantile.value = Min value

    • valueAtQuantile.quantile = 0.99 with valueAtQuantile.value = p99 value

    • valueAtQuantile.quantile = 0.999 with valueAtQuantile.value = p99.9 value

    • valueAtQuantile.quantile = 1.0 with valueAtQuantile.value = Max value

Resources that consume the metric stream can calculate the Average statistic as Sum/SampleCount.

Translating units

CloudWatch units are mapped to the case-sensitive variant of the Unified code for Units of Measure, as shown in the following table. For more information, see The Unified Code For Units of Measure.

Units that are combined with a slash are mapped by applying the OpenTelemetry conversion of both the units. For example, Bytes/Second is mapped to By/s.
