PROBLEM TO BE SOLVED: To provide a method of easily calculating a parameter indicating a state of a monitored object, a method of monitoring the monitored object by using the parameter, a parameter calculating device, a state monitoring device, a state monitoring system and a computer program. SOLUTION: The waveform data indicating the state of the monitored object includes continuous large peaks having a large peak value over a specific range, in a case when the abnormality occurs on the monitored object such as a rolling bearing. The waveform data indicating the state of the monitored object is measured by a sensor 31, and then acquired by a data acquiring device 32, and the state monitoring device 1 calculates the parameter indicating the state of the monitored object on the basis of a total value m of the number of continuous peaks having the peak value within the specific range and the number of continuous large peaks, a ratio p of the maximum peak value and the peak value within the specific range, and a value of q based on the number of the continuous large peaks 2q.
