Isn't there something that informs the pilot that the plane is missing a tire/wheel or that it weighs less than it should?

An Airbus A330 (or is it a Boeng? Different articles say different things) was missing a wheel (or is it a tire?) but landed safely somehow, and the pilot didn’t even know till he landed. What happened? Is it the software on the dashboard that was out of order?
