Abstract:
1. An operation management device which acquires performance information for each of a plurality kinds of performance items from a single or a plurality of managed devices configuring a system and performs operation management of the managed devices, the operation management device comprising: an information collection module which collects at least first performance information showing a time series change in the performance information regarding a first element and second performance information showing time series change in the performance information regarding a second element out of elements, when the performance items and the managed devices are taken as the elements; a correlation model generation module which derives a correlation function between the first and second performance information, and generates a correlation model based on the correlation function; a correlation change analysis module which judges whether or not the current first and second performance information acquired by the information collection module satisfies a relation shown by the correlation function within a specific error range; a failure period extraction module which, when the correlation change analysis module judges that it is in a state where the first and second performance information does not satisfy the relation shown by the correlation function, extracts a period of that state as a failure period:, an abnormality degree change information calculating module which calculates statistical information regarding an abnormality degree that is a degree of the first and second performance information being deviated from the correlation function during the failure period extracted by the failure period extraction module as abnormality degree change information; a performance classification information accumulation module which classifies the performance in formation into a plurality of kinds and saves the information as performance classification information; and an abnormality degree distribution information calculating module which extracts the performance information and the abnormality degrees contained in the correlation changed in the failure period from the performance classification information accumulated in the performance classification information accumulation module, and calculates abnormality degree distribution information that shows the distribution of the abnormality degrees for each element of the performance information.
