<P>PROBLEM TO BE SOLVED: To find a silent fault which is not found in an error message in a system to be managed or the inconsistency of performance data. <P>SOLUTION: A storage data processing part 600 detects the period of change in time sequence data concerning the performance of the system 200 to be managed, calculates the expectation value of performance data in a future phase, based on the past time sequential data of the phase by each phase of the detected period, and stores the value. A fault determining part 500 compares the expectation value of the performance data in the calculated phase with the actual measurement value of the performance data in the system to be managed concerning the phase by each phase in the detected period, so as to determine an abnormality in the actual measurement of the performance data. <P>COPYRIGHT: (C)2010,JPO&INPIT |
