Abstract
An expert system for determining the likelihood of failure of a unit in a computer system. The operating system of the computer system maintains a log of the errors occurring for each unit in the computer system. If a predetermine number of errors have been entered in the log for a specific unit, the expert system retrieves the error entries relating to that unit and processes them to determine whether a failure is likely to occur. In this, the processing performed by the expert system is arranged so that tests relating to components of increasing particularity, and decreasing generality, are performed after the tests relating to more general components.
