ABSTRACT:
There is provided with a method including: acquiring string data made up of a plurality of monitoring items from an apparatus to be monitored at predetermined or arbitrary time intervals; storing each acquired string data in a storage temporarily; calculating an average and variation for each of the monitoring items and correlation information indicating a correlation between the monitoring items by using each string data stored in the storage; normalizing the acquired string data by using the average and the variation of each monitoring item; calculating a distance from the correlation information for normalized string data by carrying out a computation using the normalized string data and the correlation information; and deciding whether or not there is an abnormal sign in the apparatus to be monitored depending on whether or not calculated distance falls within a confidence interval set in advance for a certain probability distribution.
