A method and a system for monitoring a turbojet engine. The method acquires a signal representative of a vibratory level of an operating rotor of the turbojet engine, acquires a rotation speed of the rotor during operation, compares the amplitude of the signal with at least one predetermined threshold based on the rotor rotation speed and, in event an amplitude peak exceeds the threshold, analyzes the signal over a time slot defined around the amplitude peak to determine if the phenomenon at the origin of the amplitude peak is a mechanical shock undergone by the rotor of the turbojet engine or an electronic interference of the signal.
