Abstract: Aspects of the present invention provide a tool for analyzing and remediating an update-related failure. In an embodiment, a failure state of a computer system that has been arrived at as a result of an update is captured. A semantic diff that includes the difference between the failure state and at least one of an original state or a completion state is then computed. This semantic diff is transformed into a feature vector format. Then the transformed semantic diff is analyzed to determine a remediation for the update. Failure and/or resolution signatures can be constructed using the semantic diff and contextual data, and these signatures can be used in comparison and analysis of failures and resolutions.

Abstract: Techniques for error report processing are described herein. Error reports, received by a developer due to program crashes, may be organized into a plurality of “buckets.” The buckets may be based in part on a name and a version of the application associated with a crash.

Abstract: The present application relates to a method for determining multiple simultaneous fault conditions on complex systems. The method comprises receiving symptoms of a complex system from monitors. When some of the symptoms suggest the existence of multiple simultaneous fault conditions, then the method creates a symptom signature, creates one or more failure mode signatures, and creates an error code for each failure mode signature in regard to the symptom signature.

Each failure mode with the minimum Hamming distance and same Hamming Code are grouped together as being one of the multiple simultaneous fault conditions. All remaining failure modes with other Hamming distances are then assigned into one of the simultaneous fault conditions.
