Abstract

a processor configured;

(A) to identify a first cause event, which is the root cause of a first event identified by the event entry based on the meta rule information, and to identify a first meta rule used in the identification of the first cause event;

(B) to receive via an input device, after the identification of the first cause event, a meta recovery method, which is a method for recovering from the first cause event, and to register the meta recovery method to correspond to the first meta rule identified in (A);

(C′

) to create the expanded rule based on the meta rule information and topology information of the at least one node apparatus;

(C) to identify a second cause event, which is the root cause of a second event identified by the event entry based on the meta rule information, and to identify a second meta rule used in the identification of the second cause event;

(D) to identify a particular meta recovery method registered in the management system, which corresponds to the second meta rule identified in (C);

(E) to display the particular meta recovery method with information about the second cause event; and

(F) display, before the reception of the meta recovery method in (B), a meta recovery method registration screen including;
