func InitTracer ¶

func InitTracer(ctx context.Context, serviceName string) (func(context.Context) error, error)

InitTracer initialises the global OTel tracer provider.

If OTEL_EXPORTER_OTLP_ENDPOINT is unset it installs a no-op provider and returns immediately — callers do not need to special-case the absence. The returned shutdown function must be called before the process exits.

By default the gRPC exporter connects without TLS (suitable for a local collector). Set OTEL_EXPORTER_OTLP_INSECURE=false to enable TLS.
