Abstract

See full text

A load monitoring apparatus is provided to monitor a load state of one or more information processing apparatuses in a network and to control the load of such an information processing apparatus based on the monitoring result. Such a load monitoring apparatus comprises a measured value storage unit which stores both measured values and measurement time of performance information (for example, a queue length, a response time and the like) of each information processing apparatus; a fluctuation calculation unit which reads a plurality of measured values measured in a given time from the measured value storage unit for each information processing apparatus, and calculates a fluctuation of the plurality of measured values; and a load state judgment unit which compares the fluctuation calculated with a given threshold to judge the load state of each information processing apparatus. Using a fluctuation, the load state of an information processing apparatus in the network can be detected more accurately.
