Abstract
To determine the cause of a problem, evaluating and tracing how an individual request traverses through various components in the system makes possible new detection techniques. The present invention relates to detecting faults in a computer system. In accordance with an embodiment of the invention, a method and apparatus detects a fault in a system by receiving a request and generating a trace based on the request. The trace is a sequence of components used to service the request. The method and apparatus also compares the trace with a stored automaton to determine whether the trace is an anomaly. The stored automaton describes traces.
