Datadog

If you want to use Datadog as the trace data store, you'll configure the OpenTelemetry Collector to receive traces from your system and then send them to both Tracetest and Datadog. And, you don't have to change your existing pipelines to do so.

tip

Examples of configuring Tracetest with Datadog can be found in the examples folder of the Tracetest GitHub repo.

Configuring OpenTelemetry Collector to Send Traces to Both Datadog and Tracetest​

In your OpenTelemetry Collector config file:

  • Set the exporter to otlp/tracetest
  • Set the endpoint to your Tracetest instance on port 4317
tip

If you are running Tracetest with Docker, and Tracetest's service name is tracetest, then the endpoint might look like this http://tracetest:4317

Additionally, add another config:

  • Set the exporter to datadog.
  • Set the api pointing to your Datadog account.
  • Set the site to Datadog API datadoghq.com.
  • Set the key to your Datadog API key.
# collector.config.yaml

# If you already have receivers declared, you can just ignore
# this one and still use yours instead.
receivers:
  otlp:
    protocols:
      http:
      grpc:

processors:
  # This configuration is needed to guarantee that the data is sent correctly to Datadog
  batch:
    send_batch_max_size: 100
    send_batch_size: 10
    timeout: 10s

exporters:
  # OTLP for Tracetest
  # Send traces to Tracetest.
  # Read more in docs here: https://docs.tracetest.io/configuration/connecting-to-data-stores/opentelemetry-collector
  otlp/tracetest:
    endpoint: tracetest:4317
    tls:
      insecure: true

  # Datadog exporter
  # One example on how to set up a collector configuration for Datadog can be seen here:
  # https://docs.datadoghq.com/opentelemetry/otel_collector_datadog_exporter/?tab=onahost
  datadog:
    api:
      site: datadoghq.com
      key: ${DATADOG_API_KEY} # Add here you API key for Datadog

service:
  pipelines:
    traces/tracetest:
      receivers: [otlp]
      processors: [batch]
      exporters: [otlp/tracetest] # exporter sending traces to your Tracetest instance
    traces/datadog:
      receivers: [otlp]
      processors: [batch]
      exporters: [datadog] # exporter sending traces to directly to Datadog

Configure Tracetest to Use Datadog as a Trace Data Store​

Configure your Tracetest instance to expose an otlp endpoint to make it aware it will receive traces from the OpenTelemetry Collector. This will expose Tracetest's trace receiver on port 4317.

Connect Tracetest to Datadog with the Web UI​

In the Web UI, (1) open Settings, and, on the (2) Trace Ingestion tab, select (3) Datadog.

Trace Ingestion Settings

Connect Tracetest to Datadog with the CLI​

Or, if you prefer using the CLI, you can use this file config.

type: DataStore
spec:
  name: Datadog pipeline
  type: datadog
  default: true

Proceed to run this command in the terminal and specify the file above.

tracetest apply datastore -f my/data-store/file/location.yaml
