Transform OTLP gRPC

The following configuration example shows how you would configure a Collector instance to transform a gRPC OTLP request to its HTTP counterpart.

Prerequisites

One of the following Collector distributions:
- The Dynatrace Collector
- OpenTelemetry Core or Contrib
- A custom Builder version
The Dynatrace API endpoint URL to which the data should be exported
An API token with the relevant access scope (only required for SaaS and ActiveGate)

Demo configuration

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317

exporters:
  otlphttp:
    endpoint: ${env:DT_ENDPOINT}
    headers:
      Authorization: "Api-Token ${env:DT_API_TOKEN}"

service:
  pipelines:
    traces:
      receivers: [otlp]
      processors: []
      exporters: [otlphttp]
    metrics:
      receivers: [otlp]
      processors: []
      exporters: [otlphttp]
    logs:
      receivers: [otlp]
      processors: []
      exporters: [otlphttp]

Configuration validation

Validate your settings to avoid any configuration issues.

Components

For our configuration, we configure the following components.

Receivers

Under receivers, we specify the gRPC otlp receiver as active receiver component for our Collector instance.

Exporters

Under exporters, we specify the default otlphttp exporter and configure it with our Dynatrace API URL and the required authentication token.

For this purpose, we set the following two environment variables and reference them in the configuration values for endpoint and Authorization.

DT_ENDPOINT contains the base URL of the Dynatrace API endpoint (for example, https://{your-environment-id}.live.dynatrace.com/api/v2/otlp)
DT_API_TOKEN contains the API token

Service pipelines

Under service, we eventually assemble our receiver and exporter objects into pipelines, which explictly accept gRPC requests and forward them on HTTP to Dynatrace.

Limits and limitations

Data is ingested using the OpenTelemetry protocol (OTLP) via the Dynatrace OTLP APIs and is subject to the API's limits and restrictions. For more information see:
