Rotating machine vibration monitoring process for detecting degradations within a rotating machine providing an output axle fitted with magnetic bearings, the magnetic bearings having at least a position sensor and at least a magnetic actuator, the process provides the following steps: 1) defining a set of excitations that does not destabilizes the rotating machine, 2) injecting the set of excitations in the rotating machine through the magnetic actuators and 3) measuring the response of the rotating machine checking whether the response verifies at least one predefined criterium, 4) if it is not the case, adjusting the properties of the set of excitations and resuming the process at the injection step, 5) if the response verifies the at least one criterium, determining at least one condition indicator based on the response measured, 6) determining if an alarm is to be triggered based on the condition indicator determined.
