Abstract

Various technologies and techniques are disclosed for performing configuration debugging comparisons. Snapshots are acquired from at least two computer systems to be compared. The snapshots from the computer systems are then compared. Heuristics are used to determine which differences are actually logically equivalent and thus not to be identified as differences. Comparison results are generated and then displayed in a manner that allows a user to see one or more differences identified between the systems. A filtering feature is provided to allow the user to further filter the comparison results based on a type of issue to be diagnosed. A requirements feedback feature is provided to allow the user to add a user-identified difference as a configuration requirement to a system model.

Claims

1. A method for performing a configuration debugging comparison comprising the steps of:

acquiring snapshots from at least two computer systems to be compared;

comparing the snapshots from the computer systems;

generating comparison results based upon the comparison;

displaying the comparison results in a manner that allows a user to see one or more differences identified between the computer systems; and

providing a filtering feature to allow the user to further filter the comparison results based on a type of issue to be diagnosed.

2. The method of claim 1, wherein heuristics are used to determine if any of the one or more differences identified are logically equivalent.

3. The method of claim 2, wherein if a particular one of the differences identified is determined to be logically equivalent, then treating the particular one of the differences as though it is not a difference.

4. The method of claim 1, wherein the one or more differences comprises a plurality of differences, and wherein heuristics are used to eliminate at least one particular difference of the plurality of differences because that one particular difference is cumulative of a same issue that is already represented by another difference contained in the plurality of differences.

5. The method of claim 1, wherein the snapshots include settings that are likely to be relevant in diagnosing problems.

6. The method of claim 1, wherein the snapshots are organized in a manner that facilitates filtering and searching.

7. The method of claim 1, wherein the comparison results comprise a union of the snapshots of the systems with a comparison result for each comparison indicated.

8. The method of claim 1, wherein the comparison results comprise the one or more differences only.

9. The method of claim 1, wherein the comparison results are displayed in an updated fashion if a user uses the filtering feature to filter the comparison results based on the type of issue to be diagnosed.

10. The method of claim 1, further comprising:

providing a requirements feedback feature that allows a user to update a system model to reflect a user-identified requirement.

11. A computer-readable medium having computer-executable instructions for causing a computer to perform the steps recited in claim 1.

12. A system for performing configuration debugging comparisons comprising:

a snapshot acquisition feature that is operable to acquire snapshots of at least two computer systems;

a heuristic comparison feature that is operable to compare the snapshots of the computer systems and generating a comparison results output;

a results display feature that is operable to display the comparison results output; and

a filtering feature that is operable to allow a user to filter the comparison results output based on a type of problem being diagnosed.

13. The system of claim 12, further comprising:

a requirements feedback feature that is operable to allow the user to add a user-identified difference as a configuration requirement to a system model.

14. The system of claim 12, wherein the heuristic comparison feature is operable to identify at least one difference between the systems that are logically equivalent.

15. The system of claim 14, wherein the at least one difference that is identified as logically equivalent is not identified as a difference by the results display feature.

16. A method for performing a configuration debugging comparison comprising the steps of:

accessing snapshot data acquired for at least two computer systems;

comparing the snapshot data for a plurality of system settings to identify if one or more differences exist;

generating comparison results data that contains the results of the comparison;

using the comparison results data to display the results to a user; and

providing a requirements feedback feature for allowing the user to add a user-identified difference as a configuration requirement to a system model.

17. The method of claim 16, wherein the snapshot data comprises settings that are likely to be relevant in diagnosing configuration problems.

18. The method of claim 16, further comprising:

providing a filtering feature to allow the user to filter the comparison results data based upon a type of problem to be diagnosed.

19. The method of claim 16, further comprising:

if one or more differences are determined to exist, using heuristics to determine if any of the one or more differences are actually logically equivalents.

20. A computer-readable medium having computer-executable instructions for causing a computer to perform the steps recited in claim 16.
