Abstract
Embodiments of the present disclosure relate to a method, apparatus, and computer program product for determining a usage change rate of a storage system. The method comprises determining a first weighted moving average of a plurality of usage change rates of a storage system during a first time window, and determining a second weighted moving average of a plurality of usage change rates of the storage system during a second time window, wherein the first time window is a latter part of the second time window. The method further comprises obtaining a third weighted moving average based on the first weighted moving average and the second weighted moving average, and determining a usage change rate of the storage system based on the third weighted moving average. By performing several weighted moving average operations on a plurality of usage change rates of the storage system in the past time, embodiments of the present disclosure can decrease the lagging and increase the sensitivity of the usage change rate for a specified time window, thereby more accurately predicting the remaining service time of storage space of the storage system.
