  • APPLICATION ERROR FINGERPRINTING
    Publication number: 20190116178
    Abstract: According to some embodiments, an application error detection platform computer processor may monitor execution of an application for a customer and determine that an application error has occurred. Responsive to the determination that an application error has occurred, an error fingerprint creation platform computer processor may access a stack trace representing execution of the application when the application error occurred. An error fingerprint associated with the occurrence of the application error may then be determined by applying a hash function (e.g., SHA-1) to information contained in the stack trace. Electronic records including an indication of the error fingerprint may then be received by and stored in an application error log data store. The application error log data store may then be searched for duplicate error fingerprints to facilitate application error resolution.
