type CheckerFunc ¶

type CheckerFunc func(ctx context.Context) error

CheckerFunc wraps the CheckHealth method.

CheckHealth returns nil if the resource is healthy, or a non-nil error if the resource is not healthy. CheckHealth must be safe to call from multiple goroutines.

type Handler ¶

type Handler struct {
	// contains filtered or unexported fields
}

Handler is an HTTP handler that reports on the success of an aggregate of Checkers. The zero value is always healthy.

func (h *Handler) AddChecker(name string, c CheckerFunc)

func (h *Handler) AddObserver(name string, c CheckerFunc)

func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request)
