Configure OpenTelemetry (OTLP) export to send audit logs, metrics, and traces to any OTLP-compatible backend.

​
Prerequisites

  • Golf Gateway deployed and running
  • OpenTelemetry Collector or compatible backend (Grafana, Datadog, etc.)

​
Configure OTLP export

gRPC (Recommended):
exporters:
  otel:
    - name: primary-otel
      enabled: true
      endpoint: otel-collector.example.com:4317
      protocol: grpc
      service_name: golf-gateway
      export_logs: true
      export_metrics: true
HTTP/Protobuf:
exporters:
  otel:
    - name: primary-otel
      enabled: true
      endpoint: https://otlp.example.com/v1/logs
      protocol: http/protobuf
      service_name: golf-gateway
      headers:
        Authorization: "Bearer ${OTEL_TOKEN}"

​
Export signals

SignalYAML FieldDescription
Logsexport_logs: trueAudit log entries
Metricsexport_metrics: truePerformance metrics
Tracesexport_traces: trueRequest traces

​
Resource attributes

Golf Gateway includes these resource attributes:
AttributeValue
service.nameFrom service_name field
service.versionGateway version
golf.gateway.idGateway ID (if managed)
golf.gateway.nameGateway name
Add custom attributes: 
exporters:
  otel:
    - name: primary-otel
      # ... other fields
      resource_attributes:
        environment: production
        region: us-west-2

​
Semantic conventions

Log records follow OpenTelemetry semantic conventions:
AttributeDescription
event.nameEvent type
http.request.methodHTTP method
url.pathRequest path
mcp.methodMCP method
mcp.tool.nameTool name

​
Common OTLP backends

Consult your observability platform’s documentation for OTLP endpoint configuration:
PlatformDocumentation
Grafana CloudSend data via OTLP
DatadogOpenTelemetry in Datadog
New RelicOpenTelemetry setup
HoneycombOpenTelemetry overview

​
Verify export is working

  1. Check health endpoint includes OTEL status
  2. View logs in your OTLP backend
  3. Search for service.name: golf-gateway

​
Troubleshooting

  • Connection timeout: Verify endpoint is reachable
  • 401/403 errors: Check authentication headers
  • No data appearing: Verify export_logs: true in your YAML config
