A method and an apparatus for monitoring and supervising the lubricant content of elevator ropes in an elevator, which includes at least a hoisting machine provided with a drive motor, the hoisting machine including at least a traction sheave, around which one or more elevator ropes are fitted side-by-side, which ropes move under the effect of friction along with the rotational movement of the traction sheave and at the same time move the elevator car. The lubricant content is monitored and supervised by the aid of a magnetic measuring device disposed in the immediate proximity of the traction sheave and the elevator ropes by collecting in the measuring device the metal dust detaching in connection with wear of the traction sheave and of the elevator ropes during operation of the elevator and by letting the metal dust switch on an alarm about a lubricant content of the elevator ropes that is too low.
