    • Provided is a monitoring system including an operation results acquisition unit that acquires time series data of each of a plurality of indexes that indicate operation results of a monitoring target; an overall index generation unit that produces time series data of an overall index by combining a plurality of index values at a same time point based on the time series data of each of the plurality of indexes; and a change point detection unit that analyzes the time series data of the overall index, and detects a point where a significant change appears in the overall index values, as a change point in a status of the monitoring target.
    • 提供一种监视系统,其包括:操作结果获取单元,其获取指示监视目标的操作结果的多个索引中的每一个的时间序列数据; 综合索引生成单元,其基于多个索引中的每一个的时间序列数据,通过组合同一时间点处的多个索引值来生成整体索引的时间序列数据; 以及变化点检测单元,该变化点检测单元分析整体指标的时间序列数据,并且检测整体指标值中出现显着变化的点作为监测目标的状态中的变化点。
