LIFE-AND-DEATH MONITORING DEVICE, LIFE-AND-DEATH MONITORING SYSTEM, LIFE-AND-DEATH MONITORING METHOD, AND LIFE-AND-DEATH MONITORING METHOD PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a life-and-death monitoring device for performing life-and-death monitoring of a multi server system for providing a service by combining plural servers having different functions each other.SOLUTION: A life-and-death monitoring device 30 comprises: a life-and-death monitoring request sending part 31 for requesting life-and-death monitoring of a multi-server system 100 which provides a service by combining plural servers having different functions each other, by sending a service request signal of the multi-server system; and a life-and-death monitoring part 32. The life-and-death monitoring request sending part 31 requests the life-and-death monitoring for monitoring normality of the multi-server system 100 by sending a normal service request signal which the system uses, to the multi-server system 100. The life-and-death monitoring part 32 performs the life-and-death monitoring based on a status code of a response signal to the service request signal.SELECTED DRAWING: Figure 1
