Abstract

PURPOSE:To switch instantly a pattern with high emergency by storing pattern data required to be displayed at high speed in a refresh buffer and rewriting the refresh buffer at each display for pattern data not requiring high speed. CONSTITUTION:When a pattern data (k) desired to be supervised is inputted from a keyboard section 54, a processor 51 compares its pattern number with high-speed pattern data (m). When the data (k) is smaller, the display content of a display section 55 is switched instantly into the pattern data (k) by switching the buffer into a refresh buffer 52k of the display section 55. On the other hand, when the pattern number (k) is larger than (m), an interface adaptor 53 is controlled and the transmission request of the pattern data (k) is performed in the processor via an interface 6. Then a processor 41 of the processing unit transmits the pattern data (k) of a storage section entry 42k of a storage section 42 to a display device via the interface 6 under the control of a display control adaptor 46.

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 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 limitations, it is necessary to set up multiple display screens and switch between them using a keyboard or the like for monitoring. However, this screen switching involves redisplaying the screen and cannot be done instantly, so it has the disadvantage that it is inferior to conventional panel-type monitoring devices in cases where instantaneous screen switching is required with a high degree of urgency. Ta.

[Purpose of the invention]

An object of the present invention is to provide a plurality of buffers for refreshing the display section, which is usually one in a display device, and to enable a monitoring program to update the screen according to changes in the system state for screen contents that require rapid screen switching. By constantly updating the contents of these plurality of refresh buffers 7a and simply switching to the corresponding refresh buffer in response to a screen switching instruction from the keyboard, etc., the conventional technology can be used for screen contents that can be relatively slow. It is an object of the present invention to provide a monitoring device which solves the above-mentioned drawbacks when rewriting a certain refresh buffer and enables instantaneous screen switching for highly urgent screen contents.

[Structure of the invention]

The present invention provides a storage device that stores a plurality of low-speed display screen data that does not need to display the status of a computer system at high speed, and a storage device that stores each of a plurality of high-speed display screen data that needs to display the status of a computer system at high speed. a plurality of first refresh buffer sections for storing; a second refresh buffer section for storing at least one of the plurality of low-speed display screen data; and a plurality of high-speed display screen data or a plurality of low-speed display screen data. If the selection instruction on the keyboard section is one of the high-speed display screen data, the corresponding storage data of the first refresh buffer is displayed; If it is one of the above, the rear cylinder 2 stores the corresponding low-speed display screen data from the storage device in the second refresh buffer.
A display device including a display unit for displaying data stored in a refresh buffer of the computer; and a computer system connected to the display device for monitoring the status of the computer system. updates the corresponding low-speed display screen data of the storage device and the corresponding high-speed display screen data of the first refresh buffer of the display device in response to the detection of a state change of the computer system through the -2-; a processing device having means for sending the corresponding low-speed display screen data to the display device in response to a request for sending the low-speed display screen data, and storing the data in a second refresh buffer of the display device; It is.

The detailed operation of the present invention will be explained using the above configuration.

In the monitoring device 2, when the power is turned on, the first processor 41 starts operating and the floppy disk device adapter 4
5, a program for controlling the monitoring device is loaded from the floppy disk 4T into the storage unit 42, and execution of the program is started.

This program first reads n pieces of monitoring screen data (1), (2), . storage unit) 4211

The display device 5 stores the screen data (1) sent from the interface 6 and the interface adapter 53 into the corresponding refresh buffer 521 of the refresh buffer unit 52 under the control of the second processor 51 . The control program for the monitoring device similarly stores high-speed screen data (2) in the storage section entry 422.

The monitoring device control program then updates screen data corresponding to state information or state change information of each device (not shown in the figure) in the computer system 1 sent via the interface 3. That is, for example, if it is necessary to update the screen data (1) at high speed,
Screen data (1) of storage section entry 42i of storage section 42
The screen data (amount) of the refresh buffer 52i of the display device 5 is updated in the same manner as described above. When slow screen data (j) needs to be updated, there is no corresponding data in the refresh buffer section 52, so the screen data (j) in the storage section entry 42j of the storage section 42 is updated.

Next, the display operation of screens related to the direct supervisor will be explained. The monitor inputs the number of the screen to be monitored, for example, "k#" for screen data, from the keyboard section 54.

The second processor 51 determines whether # is greater than or less than m in the screen number 1 input by the observer, and if it is smaller, the screen is switched to the refresh buffer 52k as the refresh buffer for the display unit 55 because it is high-speed screen data. Particularly, the display contents of the display section 55 are instantly changed to the screen data k.
Switch to # is m in the screen number "" entered by the supervisor.
If it is larger, the corresponding screen data does not exist in the refresh buffer section 52, so the interface adapter 53 is controlled and a request is made to the processing device 4 via the interface 7Ace 6 to send the screen data. The first of the processing device 4
The processor 41 is the storage unit of the storage unit 42) I74

It is controlled to use 2m+1.

In the embodiment described above, only one display device was used.
It is clear that similar control can be performed for two or more display devices.

〔Effect of the invention〕

As explained above, the present invention provides a display device with multiple refresh buffers, stores screen data that needs to be displayed at high speed in the refresh buffer, and refreshes screen data that does not need to be displayed at high speed each time it is displayed. A configuration in which the buffer is rewritten has the advantage that urgent screens can be switched instantaneously.
