SERVER MONITOR AND SERVER FAILURE DECISION METHOD FOR THE SAME

PROBLEM TO BE SOLVED: To provide a server monitor and a server failure decision method for the same, allowing quantitative and accurate decision of failure of a server device without depending on ability or experience of an operator. SOLUTION: A monitoring part 21 of the server monitor 2 repeatedly transmits a pseudo-service request to the server device 1 of a monitoring target at a prescribed period, and repeatedly measures a response time until a pseudo-service response is returned to each pseudo-service request from the server device 1. In a log file storage part 22, a measurement result of the response time is accumulated as a log file. A statistics analysis part 23 reads the log file from the log file storage part 22, estimates dispersion of a response time distribution from the measurement result of the response time, and decides that the failure occurs in the server device 1 of the monitoring target when a time change of the dispersion of the response time distribution exceeds a preset threshold value.
