PROBLEM TO BE SOLVED: To always grasp movements of a cluster group (transition of states) and to automatically change monitor settings according to them. SOLUTION: Servers 2 to 4 to be monitored including a standby server 4 are equipped with monitor processes 6, 7, and 14 for detecting abnormality of the cluster group and check processes 15, 16, and 17 for acquiring information B for checking whether the cluster group move or stop. A monitor setting process 11 of a monitor server 1 is informed of the check information B by the servers 2, 3, and 4 to be monitored and compares the check information B with a monitor setting table 13 in a memory 12 by the servers 2, 3, and 4 to be monitored to judge that the cluster group is switched between the servers 2 and 3 to be monitored and the standby server 4 when a discrepancy is found, thereby changing monitor settings for monitoring the servers to be monitored through a monitor process 5.
