A method for monitoring the health of a rotating machine mounted on a vehicle is disclosed. The method may include: receiving identifying information of the vehicle, the rotating machine, and a portable vibration sensor mounted on the rotating machine; receiving vibration data from the portable vibration sensor during a test of the rotating machine, the received vibration data being associated with the identifying information of the vehicle, the rotating machine, and the portable vibration sensor; comparing the received vibration data with known vibration data for the rotating machine; generating an alert if the received vibration data exceeds a predetermined threshold value of the known vibration data; generating a health report for the rotating machine based on the received vibration data; and transmitting the health report to a user via a web portal.
