SYSTEM ANALYSIS DEVICE AND SYSTEM ANALYSIS METHOD

摘要

In invariant relation analysis, a correlation model having high abnormality detection ability is generated.;A system analysis device (100) includes a correlation function storage unit (1022), and a correlation function extraction unit (1023). The correlation function storage unit (1022) stores a plurality of candidates for a correlation function expressing a correlation for each pair of metrics in a system. The correlation function extraction unit (1023) extracts a correlation function from a plurality of candidates for a correlation function as a correlation function for each pair of metrics, on the basis of a detection sensitivity indicating a likelihood of correlation destruction caused at the time of abnormality of a metric associated with a correlation function.

1. A system analysis device comprising:
a correlation function storage unit which stores plurality of candidates for a correlation function that represents a correlation of a pair of metrics in a system; and a correlation function extraction unit which extracts one correlation function as the correlation function for the pair of metrics from the plurality of candidates for the correlation function on the basis of a detection sensitivity indicating a likelihood of correlation destruction caused at the time of abnormality of a metric associated with a correlation function.
