[Conventional technology]

Conventionally, in expert systems for diagnosing performance problems in computer systems, performance data necessary for diagnosis is requested from the user each time during inference execution.

[Problem to be solved by the invention]

However, in the conventional method described above, when a query for performance data is made during inference execution, the user searches for and inputs the requested performance data from the huge amount of data on the performance information report that has been output in advance. was.

This has the disadvantage that it takes a lot of time to input data for one query, and if the number of queries is very large, the turnaround time until the inference is finally completed is very long. there were. Another disadvantage is that there is a possibility of misdiagnosis due to data entry errors.

The present invention solves these conventional drawbacks by automatically and quickly searching for performance data necessary for performance diagnosis from a huge group of performance data stored in performance data files. , by inputting information, eliminating the need for user intervention and realizing a more accurate and shorter diagnosis of performance problems in a computer system.
