MONITORING SYSTEM, MONITORING DEVICE, AND TEST DEVICE

摘要

A monitoring device executes: aggregating a number of messages for each type of message transmitted or received at nodes using test results; classifying the respective messages into either an original message that serves as an origin among messages transmitted and received by a system to be monitored, or a generated message that is generated in the system when the original message is transmitted to any of the plurality of nodes; analyzing a relationship between the original message and the generated message on the basis of a number of messages classified as the original message and a number of messages classified as the generated message, thereby creating a matrix indicating the relationship between the original message and the generated message; and determining that the system has undergone a failure if a value of an element inside the matrix is outside of a normal range.

主权项

1. A monitoring system, comprising:
a test device that tests a plurality of messages transmitted and received by nodes in a system to be monitored, the system to be monitored having a plurality of said nodes that can communicate with each other; and a monitoring device that monitors the system to be monitored using test results from the test device, wherein the monitoring device executes:
an aggregation process of aggregating a number of messages for each type of message transmitted or received at the nodes using the test results received from the test device;a classification process of classifying the respective messages, for which the numbers thereof were aggregated by the aggregation process, into either an original message that serves as an origin among messages transmitted and received by the system to be monitored, or a generated message that is generated in the system to be monitored when the original message is transmitted to any of the plurality of nodes;an analysis process of analyzing a relationship between the original message and the generated message on the basis of a number of messages classified by the classification process as the original message and a number of messages classified by the classification process as the generated message, thereby creating a matrix indicating the relationship between the original message and the generated message; anda detection process of determining that the system to be monitored has undergone a failure if a value of an element inside the matrix is outside of a normal range.
