A VM/370 program called Auditor detects faults in the operation of computer software subsystems and attempts to restore service as quickly as possible. Through a series of periodic tests, Auditor diagnoses whether these subsystems are operating properly. When faults are detected, service restoration procedures are automatically called, and the persons responsible for the subsystems are notified. The various types of faults are recorded for subsequent analysis.
