Abstract:
1. A method for diagnosing a detected failure in a computer system, the method comprising: comparing, in a computer process, a failure signature of the detected failure to an archived failure signature contained in a database to determine if the archived failure signature matches the failure signature of the detected failure; if the archived failure signature matches the failure signature of the detected failure, applying, in a computer process, an archived solution to the computer system that resolves the detected failure, the archived solution corresponding to a solution used to resolve a previously detected computer system failure corresponding to the archived failure signature in the database that matches the detected failure; wherein the archived failure signature is based on a set of broken computer system invariants, the set of broken computer system invariants corresponding to the previously detected computer system failure; further comprising constructing the database in a computer process prior to comparing the failure signature of the detected failure to the archived failure signature; wherein the constructing the database includes extracting invariants from the computer system; wherein the extracting the invariants includes:
