PROBLEM TO BE SOLVED: To prevent deterioration in response performance accompanied by improvement in a rapid input load or processing load.SOLUTION: A monitoring server 300 monitors a system including: a first server 200 for performing processing on the basis of an input; and a second server 100 for receiving a processing result of the first server, and for performing processing on the basis of a processing result. The monitoring server includes: reception means 310 for receiving an input amount of input; storage means 320 for storing first characteristic information indicating characteristics of the past output amount corresponding to the past input amount as the characteristics of the first server and second characteristic information indicating characteristics of delay time of the past output corresponding to the past input amount as the characteristics of the first server; estimation means 330 for estimating the output amount and output time corresponding to the input amount on the basis of the input amount and the first characteristics information and the second characteristic information; and request means 340 for requesting the second server to change the configuration of the second server on the basis of the output amount and output time estimated by the estimation means.SELECTED DRAWING: Figure 1 【課題】急激な入力負荷や処理負荷の向上に伴う応答性能低下を予防する。【解決手段】監視サーバ３００は、入力に基づき処理をする第１サーバ２００と、第１サーバの処理結果を受け付け処理結果に基づき処理をする第２サーバ１００と、を備えるシステムを監視する。入力の入力量を受信する受信手段３１０と、第１サーバの特性であって過去の入力量に対する過去の出力量の特性を示す第１の特性情報及び第１のサーバの特性であって過去の入力量に対する過去の出力の遅延時間の特性を示す第２の特性情報を記憶する記憶手段３２０と、入力量と第１の特性情報及び第２の特性情報とに基づき、入力量に対応する出力量と出力時間を推定する推定手段３３０と、推定手段が推定した出力量及び出力時間に基づき、第２サーバの構成を変更するように第２サーバへ要求する要求手段３４０と、を備える。【選択図】図１
