Functions

func Init

func Init(cfg config.OpenLitConfig, appVersion string) (func(context.Context) error, error)

Init initializes the OTLP TracerProvider pointing to OpenLit. Returns a shutdown function that must be called on app exit.

func IsEnabled

func IsEnabled() bool

IsEnabled returns true if OpenLit observability is active

func Tracer

func Tracer() trace.Tracer

Tracer returns the configured tracer (noop if disabled)
