Abstract:
1. A computer-implemented method comprising: generating a plurality of measurement values, each measurement value of said plurality of measurement values representing a value for a system measure of a plurality of system measures, wherein each system measure of said plurality of system measures represents a system measure of a computer system; detecting one or more system problems of said computer system based on said plurality of measurement values and a probabilistic model; wherein said probabilistic model defines:  wherein said probabilistic model is expressed at least in part as nodes and directed connections, wherein each directed connection of the directed connections leads from a first node to a second fault node;  wherein the first node is one of: wherein the first system measure state or the first problem represented by the first node causes a second problem represented by the second fault node; wherein detecting said one or more system problems includes for each fault node of a set of fault nodes of said probabilistic model: determining whether a problem has occurred in said computer system based at least on the aggregate probability of failure value computed for at least one fault node of said probabilistic model.
