Mapping OpenTelemetry Semantic Conventions to Service-entry Spans is now in public beta, and includes improvements to trace metrics generated from OpenTelemetry spans.

Overview

APM metrics from OpenTelemetry

To send APM stats such as hits, errors, and duration, set up the Datadog Connector.

For more information, see the OpenTelemetry project documentation for the Datadog Connector.

Setup

Add the following lines to your Collector configuration:

processors:
  probabilistic_sampler:
    sampling_percentage: 20
connectors:
    # add the "datadog" connector definition and further configurations
    datadog/connector:
exporters:
  datadog:
    api:
      key: ${env:DD_API_KEY}
service:
  pipelines:
   traces:
     receivers: [otlp]
     processors: [batch]
     exporters: [datadog/connector]
   traces/2:
     receivers: [datadog/connector]
     processors: [batch, probabilistic_sampler]
     exporters: [datadog]
  metrics:
    receivers: [datadog/connector]
    processors: [batch]
    exporters: [datadog]

Data collected
