PROBLEM TO BE SOLVED: To detect the abnormal operation of an OS or an application in an early stage, and to specify the application which has abnormally operated while decreasing the CPU load of a system. SOLUTION: Each application 1A to 1C issues information to specify its own application and application information in which application-categorized monitoring timeout time is written as a request to validate a watch dog function, and successively stores it in an FIFO memory 4 through an operating system 2, and a local CPU 5 successively reads the application information, and operates watch dog monitoring about the application-categorized timeout time. The presence/absence of abnormality is monitored by every application-categorized operation confirmation, and the monitoring is operated by the local CPU through a monitoring agent and the operating system.
