Abstract
System events preceding occurrence of a problem are likely to be similar to events preceding occurrence of the same problem at other times or on other systems. Thus, the cause of a problem may be identified by comparing a trace of events preceding occurrence of the problem with previously diagnosed traces. Traces of events preceding occurrences of a problem arising from a known cause are reduced to a series of descriptive elements. These elements are aligned to correlate differently timed but otherwise similar traces of events, converted into symbolic representations, and archived. A trace of events leading to an undiagnosed a problem similarly is converted to a symbolic representation. The representation of the undiagnosed trace is then compared to the archived representations to identify a similar archived representation. The cause of the similar archived representation is presented as a diagnosis of the problem.
