Monitoring information providing apparatus, monitoring information provides methods and monitoring information providing program

摘要

In a monitoring-information-providing apparatus 1, a storing unit 20 includes a predetermined number n of present value buffers that store acquired values in time series, and a predetermined number m of section-representative-value buffers that store a section representative value calculated using acquired values belonging to a predetermined section included in the monitoring period in time series. A storage control unit 15 performs, when a new value is acquired, a control for storing data in the present value buffers and the section-representative-value buffers. A calculating unit 13 calculates a period representative value of the monitoring period based on the new value and the section representative value stored in the storing unit 20.
