Abstract

Methods and system for exception detecting and alerting are described. An exception indicating an occurrence of an error in an application and a path to the exception in an application space may be received. The received exception may be compared to a stored exception in a prior version of an exception data structure to determine whether the received exception is a new exception. The exception data structure may include a plurality of stored exceptions. The results of the comparison may be provided.

Claims

1. A method comprising:

receiving an exception indicating an occurrence of an error in an application and a path to the exception in an application space;

comparing the received exception to a first stored exception in a new version of an exception data structure;

comparing the received exception to a second stored exception in a prior version of the exception data structure;

based on the comparisons, storing the received exception in the new version of the exception data structure, updating a first count associated with the first stored exception, or updating a second count associated with the second stored exception; and

associating a classification with the received exception based on the comparison, the classification indicating the results of the comparison.

2. The method of claim 1, further comprising:

detecting the received exception; and

accessing the path to the received exception.

3. The method of claim 1, further comprising assigning a global identifier to the received exception.

4. The method of claim 1, further comprising storing a link to a stack trace of the application at a position where the received exception occurred.

5. The method of claim 1, further comprising setting a new exception flag or an old exception flag in association with the received exception based on the comparing of the received exception to the first stored exception in the new version of the exception data structure and based on the comparing of the received exception to the second stored exception in the prior version of the exception data structure.

6. The method of claim 1, further comprising associating a priority with the received exception, the priority to define a target time period for resolving the error in the application.

7. The method of claim 1, wherein the classification includes an indication to provide an alert.

8. The method of claim 7, further comprising determining that an alert modification instruction for a reset type for the alert was received.

9. The method of claim 1, further comprising receiving a total count of an occurrence of a parameter in the application for a current time period and providing an alert if a predefined threshold is met.

10. A system comprising:

a memory to store a first stored exception in a new version of an exception data structure and to store a second stored exception in a prior version of the exception data structure; and

one or more processors to access the memory and configured to;

receive an exception indicating an occurrence of an error in an application and a path to the exception in an application space;

compare the received exception to the first stored exception;

compare the received exception to the second stored exception;

based on the comparisons, store the received exception in the new version of the exception data structure, update a first count associated with the first stored exception, or update a second count associated with the second stored exception; and

associate a classification with the received exception based on the comparison, the classification indicating the results of the comparison.

11. The system of claim 10, wherein the processor is further configured to:

detect the received exception; and

access the path to the received exception.

12. The system of claim 10, wherein the processor is further configured to assign a global identifier to the received exception.

13. The system of claim 10, wherein the processor is further configured to store a link to a stack trace of the application at a position where the received exception occurred.

14. The system of claim 10, wherein the processor is further configured to set a new exception flag or an old exception flag in association with the received exception based on the comparing of the received exception to the first stored exception in the new version of the exception data structure and based on the comparing of the received exception to the second stored exception in the prior version of the exception data structure.

15. The system of claim 10, wherein the processor is further configured to associate a priority with the received exception, the priority to define a target time period for resolving the error in the application.

16. The system of claim 10, wherein the classification includes an indication to provide an alert.

17. The system of claim 16, wherein the processor is further configured to determine that an alert modification instruction for a reset type for the alert was received.

18. The system of claim 10, wherein the processor is further configured to receive a total count of an occurrence of a parameter in the application for a current time period and providing an alert if a predefined threshold is met.

19. A non-transitory computer readable medium having instructions embodied thereon, the instructions executable by a processor for performing a method of providing an error classification, the method comprising:

receiving an exception indicating an occurrence of an error in an application and a path to the exception in an application space;

comparing the received exception to a first stored exception in a new version of an exception data structure;

comparing the received exception to a second stored exception in a prior version of the exception data structure;

based on the comparisons, storing the received exception in the new version of the exception data structure, updating a first count associated with the first stored exception, or updating a second count associated with the second stored exception; and

associating a classification with the received exception based on the comparison, the classification indicating the results of the comparison.
