Automated system problem diagnosing
First Claim
1. A method for automatically diagnosing a system problem, comprising:
- creating a problem description, wherein a problem description index is created from a group consisting of;
a line-wise index comprising a document entry in the problem description index for each line in a problem description information of a plurality of previously diagnosed problems,a description-wise index comprising a document entry in the problem description index for the problem description information of each of a plurality of previously diagnosed problems, anda set-wise index comprising a document entry in the problem description index for each set of the problem description information of a plurality of previously diagnosed problems grouped together based on a problem cause;
receiving the problem description index and problem description information of a new problem, the problem description index comprising problem description information of previously diagnosed problems, wherein said problem description information of previously diagnosed problems and of said new problem comprises text content describing system events that have occurred;
comparing problem description information of the new problem with problem description information in the problem description index, wherein comparing the problem description information of the new problem with problem description information in the problem description index for a line-wise index comprises a line-wise search of the line-wise index, wherein said line-wise search comprises searching each line of text content in the problem description index for each line of text content from the problem description information of the new problem;
computing a search score for each document in the problem description index, wherein the search score is a measure of similarity between each document in the problem description index and the problem description information of the new problem;
assigning a matching score to each of the previously diagnosed problems based on the search score, wherein the matching score is a measure of similarity between the new problem and each of the previously diagnosed problems; and
determining a diagnosis of the new problem, wherein the diagnosis of the new problem is a diagnosis of at least one of the previously diagnosed problems.

Abstract
Embodiments of the invention relate to automated system problem diagnosing. An index is created with problem description information of previously diagnosed problems, a diagnosis for each problem, and a solution to each diagnosis. System states, traces and logs are extracted from a source system with a new problem. The problem diagnosis system generates problem description information of the new problem from the system states, traces and logs. Problem description information of the new problem is compared with problem description information in the problem description index. A search score is computed for each document in the problem description index. The search score is a measure of similarity between each document in the index and the description of the new problem. A matching score is assigned to each previously diagnosed problems based on the search score. The matching score is a measure of similarity between the new problem and each previously diagnosed problem. The system determines a diagnosis and solution of the new problem based on a diagnosis and solution of one of the previously diagnosed problems.

15. A non-transitory computer-useable storage medium for automatically diagnosing a system problem, said medium having a computer-readable program, wherein a program upon being processed on a computer causes the computer to implement the steps of:
-
creating a problem description index, wherein the problem description index is created from a group consisting of; a line-wise index comprising a document entry in the problem description index for each line in a problem description information of a plurality of previously diagnosed problems, a description-wise index comprising a document entry in the problem description index for the problem description information of each of a plurality of previously diagnosed problems, and a set-wise index comprising a document entry in the problem description index for each set of the problem description information of a plurality of previously diagnosed problems grouped together based on a problem cause; receiving the problem description index and problem description information of a new problem, the problem description index comprising problem description information of previously diagnosed problems, wherein said problem description information of previously diagnosed problems and of said new problem comprises text content describing system events that have occurred; comparing problem description information of the new problem with problem description information in the problem description index, wherein comparing the problem description information of the new problem with problem description information in the problem description index for a line-wise index comprises a line-wise search of the line-wise index, wherein said line-wise search comprises searching each line of text content in the problem description index for each line of text content from the problem description information of the new problem; computing a search score for each document in the problem description index, wherein the search score is a measure of similarity between each document in the problem description index and the problem description information of the new problem; assigning a matching score to each of the previously diagnosed problems based on the search score, wherein the matching score is a measure of similarity between the new problem and each of the previously diagnosed problems; and determining a diagnosis of the new problem, wherein the diagnosis of the new problem is a diagnosis of at least one of the previously diagnosed problems. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
