# Example for Jaeger
export OTELCONFIG_EXPORTER=jaeger
export OTEL_TRACES_EXPORTER=jaeger
export OTEL_PROPAGATORS=b3multi
export OTEL_EXPORTER_OTLP_ENDPOINT=http://jaeger-collector:14268

# Example for gRPC and OTLP
export OTELCONFIG_EXPORTER=grpc
export OTEL_TRACES_EXPORTER=otlp
export OTEL_PROPAGATORS=b3multi
export OTEL_EXPORTER_OTLP_ENDPOINT=http://jaeger-collector:4317

# Example for HTTP and OTLP
export OTELCONFIG_EXPORTER=http
export OTEL_TRACES_EXPORTER=otlp
export OTEL_PROPAGATORS=b3multi
export OTEL_EXPORTER_OTLP_ENDPOINT=http://jaeger-collector:4318

Types

type TraceOptions

type TraceOptions struct {
	DefaultService     string
	NoopTracerProvider bool // Disable tracer
	NoopPropagator     bool // Disable propagator
	Debug              bool
}
