Abstract
Abstract A computer for gathering log data includes a device for normalizing the log data by cutting out values corresponding to pre-defined data items from log data in log files of respective computers on the alert and re-arranging the values of data items defined, and storing the normalized log data therein and a device for gathering the stored normalized log data into a computer having a manager function. Further, when the normalized log data have log data output times corrected on the basis of a time of the computer having the manager function, the normalized log data are stored in order of the corrected log data output times.
