Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data processing system having a response time display surface.

In an online system in which a computer on the center side and a plurality of terminal devices are connected via a line, particularly in an online real-time processing system that is one type of such system, response time is one of the extremely important matters.

For example, in an inquiry system, when an operator inputs a certain command from a terminal device and requests a computer at the center to make an inquiry, the command is sent to the center and then the processing results corresponding to the command are obtained. The response time is determined at the time of system design and investigated at the time of actual setup or after a certain period of time has elapsed. As a result, if the response time does not satisfy the specifications, it is necessary to take steps to improve the processing speed of the computer at the center or the transmission speed of the line.

The following techniques are conventionally known as methods for determining such response time. One method is to use a program to measure processing time on the center side, that is, the time from when an instruction is given to a computer until the corresponding processing result is sent out from the computer. This method uses a stopwatch or the like to monitor and measure the process from when a command is sent to when the corresponding processing result is displayed on the display screen of the terminal device.

Since the former is a measurement of the response time at the so-called center, the transmission speed of the line is not taken into account, and it does not match the response time on the terminal device side. Therefore, the conversion must be performed taking into account the transmission speed of the line, and the result does not include the waiting time of the line, making it impossible to obtain an accurate response time. In the latter case, since the measurement is performed on the terminal device side, a realistic response time can be obtained, but errors occur in the results because the measurement is performed by a human.

In view of this, the present invention provides a data processing system that accurately measures detailed response times and is provided with a display screen that displays the measured response times.

To this end, in the present invention, the response time from the time when an input command is requested to be sent to the center until the processing result corresponding to that command is displayed on a display screen is measured, and the response time is measured on a display screen different from the display surface. It is characterized by the fact that it is displayed in

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an example of a data processing system according to the present invention. 11 is a computer, which includes a data file 11a and a central processing unit 1;
1b, a main storage section 11c, a communication control section 11d, etc. The terminal device 12 is connected to the computer 11 on the center side via a line 13. The terminal device 12 includes a display control section 12a and a plurality of terminals 12b. Display control section 12a
is for multiplex control of each terminal 13a, and controls the transmission of data from each terminal 12b to the center. For this purpose, it has an interface circuit IFC for connection with the line, a select circuit SECT for switching between each terminal, a memory section MEM for screen buffer corresponding to each terminal, and a control section CONT for controlling them. The display control section 12a further includes a response time monitoring section TIW. The monitoring unit TIW has measurement, analysis, and display functional units (not shown), and is controlled by the control unit CONT.

The terminal device 12b has a display function and a data input function, and for this purpose, the display device 12b
1. It has a keyboard 12b2. Furthermore, the display terminal 12b is a display device 12b.
The second display screen has a different display device 12b3. This display 12b3 is for displaying the response time, and as shown in FIG.
It has two display items (display areas). The first item 21a displays the maximum response time,
The second item 21b displays the minimum response time, and the third item 21c displays the average value of the response times. The fourth item 21d displays the response time to the latest command.

Regarding response time, keyboard 12b
2, various modes can be set by the operator.

[Mode 1] This mode does not function at all regarding response time, and the response time monitoring section
TIW doesn't work.

[Mode 2] In this mode, the response time is measured and analyzed by operating the response time monitoring section TIW, but the result is merely stored in the display control section 12a without being displayed on the display 12b3. This stored content can later be displayed on the display 12b3 or printed on a hard copy device (not shown) according to instructions from the operator.

[Mode 3] This mode operates the measurement and display function section of the response time monitoring unit TIW to measure and display response time.
The measurement result is displayed on the fourth item 21d of the display 12b3.

[Mode 4] In this mode, the operator selects the measurement section (for example, 1
time).

As a result, the response time monitoring unit TIW operates all functions for measurement, analysis, and display, and in addition to the maximum, minimum, and average response times of all responses within the specified interval, the response time for the latest command are displayed on the display screen of the display device 12b3.

Next, the response time monitoring section TIW and the control section
Explain the relationship with CONT. Each terminal 1
2b randomly sends commands, and the commands are sent to each terminal 1 by the display control unit 12a.
2b is attached with a unique terminal code and sent to the line 13, and the processing result is sent with the terminal code attached, so that the display control unit 12a can measure the response time of each terminal. Become.

Incidentally, the response time is, of course, proportional to the amount of data entered from the terminal, and for this reason, the amount of data may be displayed or hard-copied together with the response time. In other words, the data length is displayed in bytes and hard-copied at the same time as the maximum, minimum, and average response times.

As explained above, according to the present invention, since the terminal device is provided with a response monitoring section and the result is displayed on the display, it is possible to accurately know the response time on the terminal side. It becomes possible to quickly deal with overloads on the center's computers and lines.
