Patent ID: 7617086

Claim:
A monitoring simulation device which simulates monitoring of a computer network system composed of a plurality of constituent elements including an object to be monitored, the monitoring simulation device comprising: a design data storage unit for storing design data including information based on connection and structural relationships among the constituent elements constituting the computer network system; a monitoring condition storage unit for storing a plurality of monitoring conditions for abnormality detection of an object to be monitored and error information indicating that the abnormality, which has been detected in the object, meets a monitoring condition; a design data input unit for creating from the design data, topology data representing relationships among topological elements corresponding to the constituent elements of the computer network system; a pseudo-failure setting unit simulating failure in the topological elements by placing the topological elements in pseudo-failure state one by one; a monitoring condition check unit for examining all paths from the topological element corresponding to the object constituent element to the topological element in a pseudo-failed state based on the topology data, determining whether each of the monitoring conditions stored in the monitoring condition storage unit are met with the pseudo-failure simulated by the pseudo-failure setting unit and, if any of the monitoring conditions are met, extracting all error information relevant to the met monitoring condition; and a monitoring simulation result storage unit for storing information on correspondence between a simulated failed constituent element and all the extracted error information, the information created as a monitoring simulation result in the monitoring condition check unit.
