# otel ```go import "github.com/danmestas/libfossil/observer/otel" ``` Package otel provides OpenTelemetry implementations of the libfossil SyncObserver and CheckoutObserver interfaces. Import this package only when you want OTel instrumentation — it pulls in the OTel SDK dependency. ## Index - [type CheckoutObserver](<#CheckoutObserver>) - [func NewCheckoutObserver\(\) \*CheckoutObserver](<#NewCheckoutObserver>) -
