Sending Data

This page covers how to configure OpenTelemetry Collectors and SDKs to send data to the GlassFlow OTLP receiver.

OpenTelemetry Collector

HTTP Exporter


exporters:
  otlphttp:
    endpoint: http://<glassflow-otlp-receiver>:4318
    headers:
      x-glassflow-pipeline-id: "otel-logs-pipeline"
 
service:
  pipelines:
    logs:
      receivers: [otlp]
      processors: [batch]
      exporters: [otlphttp]

gRPC Exporter


exporters:
  otlp:
    endpoint: <glassflow-otlp-receiver>:4317
    headers:
      x-glassflow-pipeline-id: "otel-logs-pipeline"
    tls:
      insecure: true  # Set to false and configure certs in production
 
service:
  pipelines:
    logs:
      receivers: [otlp]
      processors: [batch]
      exporters: [otlp]

Replace logs with traces or metrics in the service.pipelines section to match the signal type of your pipeline.

Direct SDK Instrumentation

For applications instrumented with the OpenTelemetry SDK, configure the OTLP exporter to point at GlassFlow and include the pipeline ID header.

Python example (traces):


from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
 
exporter = OTLPSpanExporter(
    endpoint="http://<glassflow-otlp-receiver>:4317",
    headers={"x-glassflow-pipeline-id": "otel-traces-pipeline"},
    insecure=True,
)
