SYSTEM DIAGNOSTICS WITH THREAD DUMP ANALYSIS

摘要

A thread dump analysis tool analyzes a series of thread dumps and identifies one or more potential problems in the application from which the thread dumps were generated. Hints regarding the potential problems are presented. The hints can be generated based on relative values generated by analysis of sequential dumps. The hints may be hints that could not be generated by analysis of a single thread dump. Other hints may be hints that are enhanced by analysis of multiple thread dumps, whose importance is made clearer by appearance in multiple thread dumps, or that are unchanged in detection, importance, or both, by the use of multiple thread dumps. The hints can then be presented in order of importance. Additionally or alternatively, hints below a certain threshold of importance can be hidden.

1. A method comprising:
accessing a first thread dump from an execution of an application; accessing a second thread dump from the execution of the application; performing, by a processor of a machine, a comparison of the second thread dump with the first thread dump; based on the comparison, identifying a problem in the execution of the application; and causing a presentation of information about the identified problem to a user.
