Operations management apparatus, operations management system, data processing method, and operations management program

A data processing method comprising:

• generating a correlation model including a plurality of correlation functions between pieces of performance information based on series of performance information each indicating time series variation of a piece of the performance information and weights each indicating a prediction error of the respective correlation functions, the pieces of performance information being acquired from one or more devices included in a system;
• and
• performing pruning of a route of the correlation model based on the weight.

A non-transitory computer readable storage medium recording thereon a program, the program causing a computer to perform a method comprising:
