Claim:
1. An operation management apparatus comprising: hardware, including a processor, memory, and a physical storage device, a correlation model storage unit implemented at least by the physical storage device and which stores a correlation model indicating a correlation for each pair of different metrics in a state of executing a predetermined program in a first processing system, the correlation indicating a relationship between a pair of time series data of the different metrics; a benchmark performance collection unit implemented at least by the processor and the memory and which selects a metric having a correlation with another metric in the correlation model in a state of executing a predetermined benchmark process in the first processing system and a second processing system, respectively, and collects values of the selected metric; a performance comparison unit implemented at least by the processor and the memory and which calculates and outputs a performance ratio of a metric in the second processing system to the metric in the first processing system, based on the values of the selected metrics in the state of executing the predetermined benchmark process in the first processing system and the second processing system, respectively; and wherein the performance comparison unit corrects, with respect to the pair of metrics having the correlation in the correlation model, a benchmark performance ratio so that a ratio of the benchmark performance ratio of a metric to the benchmark performance ratio of the other metric is equal to a value of a coefficient of a correlation function that represents the correlation and a value of the benchmark performance ratio after the correction is equal to or smaller than a value of the benchmark performance ratio before the correction.
