Identifying and grouping program run time errors

摘要

A stack trace associated with an application program is received and at least one recognizable term is searched for in the stack trace. A digital signature is generated from at least a portion of the stack trace that includes the at least one recognizable term. If the digital signature matches a known digital signature among a plurality of known digital signatures, the stack trace is grouped with other stack traces associated with the known digital signature. Method call graphs in grouped stack traces may be analyzed to determine common pathways leading to an error.

1. A method comprising:
receiving a stack trace associated with an application program; searching for at least one recognizable term in the stack trace; generating a digital signature from at least a portion of the stack trace that includes the at least one recognizable term; determining whether the digital signature matches a known digital signature of a plurality of known digital signatures; in response to determining that the digital signature matches a known digital signature among the plurality of known digital signatures, grouping the stack trace with other stack traces associated with the known digital signature; analyzing method call graphs of a group of stack traces associated with a known digital signature; determining a common pattern among pathways leading to an error in the method call graphs of the group of stack traces associated with the known digital signature.
