Abstract: A work machine monitoring system includes a measurement data acquisition unit that acquires measurement data of a ground on which a work machine travels by contact of a rotating member included in the work machine and rotation of the rotating member, a determination criteria setting unit that sets determination criteria for determining presence or absence of a boulder on the ground in the measurement data, a boulder determination unit that determines the presence or absence of the boulder on the ground in the measurement data based on the determination criteria, and a warning control unit that outputs a warning from an output device based on determination of the presence or absence of the boulder.
