Disk exhaustion prediction program, information processing apparatus, and disk exhaustion prediction method

摘要

PROBLEM TO BE SOLVED: To suppress a deterioration in the accuracy of predicting a free space of a disk at a time point in the future.SOLUTION: An information processing apparatus 101 calculates, with D1 as a reference date, a prediction date on which a free space of a disk A is reduced to a free space threshold or less for each of combinations of D1 and D2 to D4. The information processing apparatus 101 calculates, with D2 as a reference date, a prediction date on which the free space of the disk A is reduced to the free space threshold or less for each of combinations of D2 and D3 to D5. The information processing apparatus 101 determines, on the basis of the number of times of the appearance of the calculated prediction dates for the combinations, a depletion prediction date on which the free space of the disk A is reduced to the free space threshold or less. In examples of graphs 111-1 and 2, the information processing apparatus 101 determines a prediction date P as the depletion prediction date, as intersections of primary expressions for combinations of each of the plurality of reference dates and past dates previous to each of the reference dates, and a straight line indicating the free space threshold, P appears most.SELECTED DRAWING: Figure 1
