Summary: | PROBLEM TO BE SOLVED: To calculate a correlation coefficient between hierarchies free from influences due to entire hierarchy request.SOLUTION: A performance diagnostic server 100 acquires a time-series data which represents execution frequency at every time from a multi-hierarchy system 70 to calculate a correlation coefficient between processing types executed by the server between the respective hierarchies based on the time-series data. The performance diagnostic server 100 calculates a partial correlation coefficient in which influences of trend among entire multi hierarchies is removed from the correlation coefficient between the respective processing types and updates the correlation coefficient between the respective processing types using the calculated partial correlation coefficient.
【課題】階層全体のリクエストによる影響を除いた処理間の相関係数を算出すること。【解決手段】性能診断サーバ100は、多階層システム70から、時刻毎の実行回数を示す時系列データを取得し、時系列データを基にして、各階層でサーバに実行される処理タイプ間の相関係数を算出する。性能診断サーバ100は、各処理タイプ間の相関係数から、多階層全体のトレンドの影響を除去した偏相関係数を算出し、算出した偏相関係数によって、各処理タイプ間の相関係数を更新する。【選択図】図1 |
