Patent number: 9958843Abstract: A management system has a topology display screen of a management target system with an area, where icons of system components are typically displayed in the related art, which is embedded and displayed with a graph of a monitor value of the system component. A band having a predetermined width is displayed to show a relation between system display objects indicating the system components. The width of the band is determined by the number of requests which are transmitted or received by the system components. When a time-sequential graph of the monitor value of a system component is displayed, a vertical bar which can be operated by an input/output device is displayed in the graph. When the operation of the vertical bar is detected, an icon indicating integrity of the management target system at a time indicated by the vertical bar is displayed in the vicinity of the vertical bar.Type: GrantFiled: November 7, 2012Date of Patent: May 1, 2018Assignee: Hitachi, Ltd.Inventors: Kenta Yamasaki, Mariko Miyaki, Yoko Shiga, Tomohiro Morimura
