Abstract: In a method for monitoring a geared motor, and a system, the geared motor has a gearbox at least partially filled with oil. A measure of the oil level, e.g., a measure of the filling-level height of the oil, is captured, and a measure of vibration is captured at at least one point of the gearbox. A first variable is formed by combining the measure of the oil level and the measure of vibration, and it is monitored whether the value of the first variable exceeds a permissible extent of deviation from a setpoint value or exceeds a threshold value.
