Operation management device, operation management method, and operation management program

摘要

An operation management device includes: an information collection module which collects, from a managed device, first and second performance information showing a time series change in the performance information; a correlation model generation module which derives a correlation function between the first and second performance information and creates 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 satisfy the relation shown by the conversion function between the first and second performance information of the correlation model within a specific error range; and a failure period extraction module which, when the first and second performance information does not satisfy the relation shown by the conversion function of the correlation model , extracts a period of that state as a failure period.

主权项

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:
a failure analysis module which detects generation of failure from the acquired performance information; an abnormality degree distribution information calculation module which calculates abnormality degree distribution information that shows the distribution of the abnormality degrees for each element of the performance information for each failure period in which the failure is generated; a past failure information accumulation module which accumulates a history of failures analyzed by the failure analysis module; and a similar failure search module which compares the history of failures stored in the past failure information accumulation module with the abnormality degree distribution information to search the failure similar to the abnormality degree distribution information.
