摘要

log acquisition unit (106), input information input section (104) has acquired and based on the type definition (112), it is determined to extract the log type from the log of the monitored system, to create the first log data. Log distribution estimating unit (108), the second log data extracted on the basis of the type defined as (112) a first log data to estimate the distribution density function representing the true distribution. Log distribution estimating unit (108) selects a specific range satisfying the distribution density function, creates a third log data from the second log data. Resource Utilization predictor (110) calculates the predicted value of the constant and the prediction type of the third, based on the log data and the calculated resource usage above a threshold load definition (114) from the resource utilization.
