MONITORING PROGRAM, MONITOR AND MONITORING METHOD

摘要

A tree-structure data generating section (12) acquires tree-structure data including state information such as normal or failure indicating the state of monitoring object servers (41 to 43) and nodes in the lower layer. A propagation processing section (13) then judges whether or not to propagate the state information on a predetermined node out of these nodes to a node in the upper layer of the predetermined node. The propagation processing section, when judging the state information to be propagated, propagates the state information according to the result of the comparison between the state information on the predetermined node and the state information on the node in the upper layer of the predetermined nodes. The propagation processing section, when judging it not to be propagated, maintains the state information on the node in the upper layer.
