Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a monitoring device that monitors the status of a computer system and displays the monitoring results.

[Prior art]

Conventionally, this type of monitoring device has displayed the system configuration of a computer system and the status of each component device on a panel consisting of a combination of lamps. Normally, the number of devices in a system and the connection relationships between devices, that is, the system configuration, differ from system to system, so a monitoring device had to be developed for each system. For this reason, in recent years, program-controlled monitoring devices have been realized that use display devices to programmatically display monitoring results. This program-controlled monitoring device has the feature that it can handle various systems simply by changing the monitoring device control program, without the need to develop a monitoring device for each system. Due to physical constraints, it is necessary to set up multiple screens and switch between them using a keyboard or the like for monitoring. For this reason, it has the disadvantage that it is inferior to conventional panel-type monitoring devices in terms of visibility and operability. This drawback can be solved by installing multiple display devices, but since the number of screens to be displayed is generally greater than the number of display devices, it is necessary to manage which screen is displayed on which display device, and it is necessary to manage which screen is displayed on which display device. The drawback was that the program was complicated. Another disadvantage is that the program for controlling the monitoring device becomes increasingly complex, as the number of display devices increases or decreases due to the addition of a display device or failure of the display device, and the need to replace it with another display device. .

[Purpose of the invention]

An object of the present invention is to provide each of a plurality of display devices with a number of buffers corresponding to the number of display screens, and a program for controlling a monitoring device simply writes display contents to the buffers corresponding to the monitoring screens of all display devices. The above disadvantages can be solved by displaying the contents of the corresponding buffer using the keyboard provided on the display device, regardless of the program for controlling the monitoring device. To provide a monitoring device that can easily display any monitoring screen on each □ display device without complicating a control program.

[Structure of the invention]

The present invention provides a plurality of buffer sections that store status display contents of a computer system, a keyboard section that selects and instructs one of the buffer sections, and a display section that displays the status display contents of the buffer section selected by the keyboard section. and an open status notification interface with the computer system to monitor the status of the computer system, and is composed of the multiple display units and a connected processing unit, and is configured to display the status of the computer system. By writing the same status display contents to the corresponding buffer sections of all or some of the display devices when displaying a status change or displaying a status change, the supervisor can display any status display screen on any of the above display devices. This allows the computer system status to be monitored by displaying it.
