The monitoring system includes a controller to cause the elevator car to travel to a predefined position in the hoistway, a sensor to sense a position of the counterweight with the elevator car stopped at the predefined position and to generate data corresponding to sensing results and a processor operably coupled to the sensor and configured to analyze the data and to calculate, based on analysis results, an elongation of the tension member.
