Abstract:
1. A load monitoring apparatus for monitoring a load state of an information processing apparatus, comprising: a measured value storage unit which stores measured value information indicating at least one of a queue length as a number of requests held in a queue of said information processing apparatus or a response time for a request processed by said information processing apparatus along with a measurement time; a measured value collection unit which receives the measured value information and the measurement time from said information processing apparatus in real time, and stores the measured value information and the measurement time in said measured value storage unit; a fluctuation judgment unit, in a predetermined timing, which reads a plurality of measured values from said measured value storage unit for a predetermined period, calculates a sum of a number of measured values which is larger than a first threshold and a number of measured values which is less than a second threshold smaller than said first threshold among the plurality of measured values for the predetermined period, and judges that the plurality of measured values for the predetermined period are in a large fluctuation state when the calculated sum is larger than a predetermined load state judgment threshold; and a load state notification unit which notifies of a load state of said information processing apparatus being in a symptom state just before a high load state when the plurality of measured values for the predetermined period are judged to be in said large fluctuation state by said fluctuation judgment unit; a configuration information storage unit which stores configuration information of said information processing apparatus; and a threshold calculation unit which calculates said predetermined load state judgment threshold corresponding to performance of said information processing apparatus based on the configuration information stored in said configuration information storage unit.
