Abstract

Embodiments of the invention provide techniques for troubleshooting of computer systems using a fault tree analysis. In one embodiment, data parameters describing a status of a system may be monitored to determine the existence of a fault. In the event of a fault, fault tree analysis metadata may be evaluated to attempt to determine a root cause of the fault. If a root cause can be automatically determined, it may be presented to a user in a troubleshooting console, or may be used to trigger an automated corrective action. Alternatively, if a root cause cannot be automatically determined, the user may be presented with additional fault tree analysis metadata and any relevant data parameters in the troubleshooting console, so that the user may determine the root cause of the fault event.

Claims

1. A computer-implemented method for troubleshooting a computer system, comprising:

detecting a fault event in the computer system, wherein the computer system is executing at least one software application;

retrieving a data structure storing a fault tree analysis describing the fault event, wherein the fault tree analysis specifies a hierarchical structure specifying one or more symptoms associated with the detected fault event and one or more root causes associated with the detected fault event;

retrieving one or more data values describing an operational status of the computer system;

determining, based on the fault tree analysis and the one or more data values, a predicted root cause for the fault event; and

presenting the predicted root cause on a user interface.

2. The computer-implemented method of claim 1, wherein the one or more data values describe the status of the computer system at the time of the fault event.

3. The computer-implemented method of claim 1, wherein the fault tree analysis is formatted using at least one of the XML, DITA, and HTML data formats.

4. The computer-implemented method of claim 1, further comprising:

presenting, within the user interface, at least one selectable action to correct the root cause;

receiving a user selection of one of the at least one selectable action; and

performing the selected action.

5. The computer-implemented method of claim 4, further comprising, storing the performed action for future use in troubleshooting the computer system.

6. The computer-implemented method of claim 1, further comprising:

determining an action to correct the root cause; and

performing the determined action.

7. The computer-implemented method of claim 1, further comprising:

receiving, within the user interface, one or more user modifications to the fault tree analysis; and

storing the one or more user modifications in the fault tree analysis for future use in troubleshooting the computer system.

8. The computer-implemented method of claim 7, wherein the fault tree analysis is shared by a community of users, such that the one or more user modifications may be accessible to members of the community of users when the fault event is detected.

9. A computer useable storage medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform an operation, comprising:

detecting a fault event in the computer system, wherein the computer system is executing at least one software application;

retrieving a data structure storing a fault tree analysis describing the fault event, wherein the fault tree analysis specifies a hierarchical structure specifying one or more symptoms associated with the detected fault event and one or more root causes associated with the detected fault event;

retrieving one or more data values describing an operational status of the computer system;

determining, based on the fault tree analysis and the one or more data values, a predicted root cause for the fault event; and

presenting the predicted root cause on a user interface.

10. The computer useable storage medium of claim 9, wherein the one or more data values describe the status of the computer system at the time of the fault event.

11. The computer useable storage medium of claim 9, wherein the fault tree analysis is formatted using at least one of the XML, DITA, and HTML data formats.

12. The computer useable storage medium of claim 9, wherein the operation further comprises:

presenting, within the user interface, at least one selectable action to correct the root cause;

receiving a user selection of one of the at least one selectable action; and

performing the selected action.

13. The computer useable storage medium of claim 12, wherein the operation further comprises, storing the performed action for future use in troubleshooting the computer system.

14. The computer useable storage medium of claim 9, wherein the operation further comprises:

determining an action to correct the root cause; and

performing the determined action.

15. The computer useable storage medium of claim 9, wherein the operation further comprises:

receiving, within the user interface, one or more user modifications to the fault tree analysis; and

storing the one or more user modifications in the fault tree analysis for future use in troubleshooting the computer system.

16. The computer useable storage medium of claim 15, wherein the fault tree analysis is shared by a community of users, such that the one or more user modifications may be accessible to members of the community of users when the fault event is detected.

17. A system, comprising:

a processor; and

a memory containing a monitoring program configured to monitor the availability of a networked software application, wherein the monitoring program, when executed on the processor, is configured to;

detect a fault event in the computer system, wherein the computer system is executing at least one software application;

retrieve a data structure storing a fault tree analysis describing the fault event, wherein the fault tree analysis specifies a hierarchical structure specifying one or more symptoms associated with the detected fault event and one or more root causes associated with the detected fault event;

retrieve one or more data values describing an operational status of the computer system;

determine, based on the fault tree analysis and the one or more data values, a predicted root cause for the fault event; and

present the predicted root cause on a user interface.

18. The system of claim 17, wherein the one or more data values describe the status of the computer system at the time of the fault event.

19. The system of claim 17, wherein the fault tree analysis is formatted using at least one of the XML, DITA, and HTML data formats.

20. The system of claim 17, wherein the monitoring program is further configured to:

present, within the user interface, at least one selectable action to correct the root cause;

receive a user selection of one of the at least one selectable action; and

perform the selected action.

21. The system of claim 20, wherein the monitoring program is further configured to store the performed action for future use in troubleshooting the computer system.

22. The system of claim 17, wherein the monitoring program is further configured to:

determine an action to correct the root cause; and

perform the determined action.

23. The system of claim 17, wherein the monitoring program is further configured to:

receive, within the user interface, one or more user modifications to the fault tree analysis; and

store the one or more user modifications in the fault tree analysis for future use in troubleshooting the computer system.

24. The system of claim 23, wherein the fault tree analysis is shared by a community of users, such that the one or more user modifications may be accessible to members of the community of users when the fault event is detected.
