Abstract
A method for identifying names of uninformative functions in call-stack traces is described. The method comprises the steps of obtaining a set of call-stacks and information indicative of which call-stack traces in the set match a particular call-stack trace; for each matching call-stack trace pair, incrementing a false negative counter for each function name above a first matching function name in a respective call-stack trace pair; for each non-matching call-stack trace pair, incrementing a false positive counter for each function name above a first non-matching function name in a respective call-stack pair; incrementing a frequency counter for each function name appearing in each of the call-stack traces; calculating an aggregate value for each of the function names as a function of respective ones of the false positive counter, the false negative counter and the frequency counter; and identifying uninformative ones of the function names based on the respective aggregate values. The method may be used to diagnose software problems based on known software problems and is useful in helpdesk and autonomic computing applications.
