Functions

func Install

func Install(ctx context.Context, cfg Config) (shutdown func(context.Context) error, err error)

Install configures the global TracerProvider and text map propagator. If cfg.OTLPEndpoint is empty, it returns (nil, nil) and leaves OTel defaults (noop) in place.

Types

type Config

type Config struct {
	ServiceName    string
	ServiceVersion string
	OTLPEndpoint   string
	Insecure       bool
	SampleRatio    float64
}

Config controls OTLP export. Endpoint is the gRPC host:port (no scheme), e.g. "localhost:4317" or "tempo:4317".
