Selective diagnostics for computing systems

Abstract:

Method and systems for generating an adjacency matrix A and a directional relation graph representing a relationship between one or more diagnostics. The adjacency matrix with all zero's is initialized. One or more entries in the adjacency matrix A are revised by, for each source diagnostic s, decreasing a corresponding count A(s,d) in the adjacency matrix A to decrease a corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d passing; increasing the corresponding count A(s,d) in the adjacency matrix A to increase the corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d failing; and maintaining a current value of the corresponding count A(s,d) in the adjacency matrix A in response to the diagnostic s passing or having no corresponding data. The directional relation graph is generated based on the adjacency matrix A.
