Instruments outgoing HTTP requests, exports spans to PingOps backend via OTLP, and supports manual tracing with custom attributes, domain filtering, and header redaction.
This exporter has been deprecated. To export your OTLP traces from OpenTelemetry SDK directly to Datadog Agent, please refer to OTLP Ingest in Datadog Agent: https://docs.datadoghq.com/tracing/setup_overview/open_standards/#otlp-ingest-in-datadog-agent. opentelemetry-exporters-datadog is Datadog’s trace exporter for the OpenTelemetry Ruby tracing library, which is used to trace requests across web servers, databases and microservices. The exporter formats and sends these traces to a Datadog Agent so that they can be ingested, stored, and analyzed with Datadog.
