INFORMATION PROCESSOR, FAILURE DETECTION METHOD IN INFORMATION PROCESSOR, AND FAILURE DETECTION PROGRAM IN INFORMATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide an information processor capable of quickly and reliably detecting a failure, a failure detection method in the information processor, and a failure detection program in the information processor.SOLUTION: Load factor measurement means 341 measures the load factor of a CPU. Information storage means 342 stores numerical value information indicating a numerical value for calculating the software processing amount of the CPU in accordance with software processing executed in the CPU. Load factor calculation means 343 calculates the software processing amount on the basis of a received packet and the numerical value information stored in the information storage means 342. Then, the load factor calculation means 343 calculates the standard load factor of the CPU on the basis of the calculated software processing amount and the software processing capability of the CPU. Failure determination means 344 determines the presence/absence of a failure on the basis of the measurement result of the load factor measurement means 341 and the calculation result of the load factor calculation means 343.
