Abstract

PURPOSE:To measure telegram processing time and at the same time to measure computer usage rate by simplifying input/output telegram printing timing so that the total processing time of telegram is measured and also by reducing the printing frequency so that such printing processing time becomes negligible. CONSTITUTION:When a start command is inputted, a circuit processing task 4 of a computer 1 to be measured begins to work at the 1st telegram reception (a) then a telegram processing task is controlled. Telegram processing task 5 actuates an empty time processing task 7 and activates a processing loop, and at the same time prints out (b) the measuring start time. After the telegram is processed, a response telegram is sent (c) to a terminal 2 through the circuit processing task 4. During the empty time for completion of telegram transmission, the waiting time measuring task 7 is activated (d). By a transmission completion interruption (e), the circuit processing task 4 is again activated and enters the next cycle of telegram reception processing. When the final telegram is received (f) by termination command or by the coincidence of telegram processing command number, a termination time is printed at the telegram processing task 5 at the same time when the telegram processing is completed and the processing loop is turned off (g).

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a system for measuring the usage status of Shisuisho, and more particularly to a system for simultaneously measuring the processing time of a message in an online computer and the usage rate of a calculator used for this processing. .

Prior Art The conventional method for measuring message processing time in online computer systems is to stamp the time using a built-in clock when sending a message, and to print the output time in the same way when outputting the message after processing is completed. The difference is taken as the message processing time. .

According to the above method, it is difficult to determine the timing of stamping the input/output message time, and the time that should normally be measured as processing time cannot be measured, and the accuracy of the computer's built-in clock has a large effect on the measurement results. . Furthermore, there is a drawback that the J11 power usage rate, which is closely related to message processing time, cannot be measured at the same time.

OBJECTS OF THE INVENTION The present invention has been made to eliminate the drawbacks of the above-mentioned conventional ones, and its purpose is to simplify the input/output message stamping timing so that the total processing time of the message can be measured; To provide a computer usage measurement system in which marking processing time can be ignored by reducing the number of markings.

fruit” [retroactive The present invention will be described in detail below using the drawings.

FIG. 1 is a diagram showing a schematic processing configuration of a system according to an embodiment of the present invention, in which 1 is an online calculation 4 and a measurement target F
[is. 2 is a terminal connected to this online computer 1, and 3 is an operator console. The processing configuration of the online computer 1 includes a line processing task 4, a message processing task 5, a console processing task 6, an idle time measurement task 7, a calculation task 8, and a measurement task for controlling various measurement states. It consists of table 9.

As shown in FIG. 2, this measurement table 9 includes a control area 919, a time start time area 92. Measurement end time area 93. It has a message processing command number area 94, a message processing counter area 95, and a loop counter area 96.

A measurement start command is input from the operation console 3 and sent to the message processing task 5 via the console processing task 6. At this point, in the first method (the method corresponding to claim 1), the message processing task 5
turns on the start flag of the measurement table 9. In the second method (corresponding to claim 2),
This start flag is turned on, and the number of message processing commands is also preset and stored in the message processing command number area 94 of the measurement table.

When a message is input from terminal group 2, times i! This is notified to the message processing task 5 via the 1lffi processing task 4, and since this is the first message after the start command has been input, measurement is subsequently started. In other words, message processing task 5
At the same time, the message processing is carried out within the free time measuring task 7, and a predetermined processing loop set in advance within the free time measuring task 7 is activated. Thereafter, the measurement start time is stamped in the measurement start time area 92 of the measurement table 9. Further, after adding 1 to the message processing counter area 95, the message is processed and a response is returned to the terminal group 2.

For subsequent reception from the second message, in the first method, 1 is simply added to the message processing counter area 95, and in the second method, in addition to this addition of 1, the number of message processing commands is added. The contents of area 94 and message processing counter area 95 are compared.

The idle time measurement task 7 operates when no message processing is being performed, such as when waiting for an interrupt, and when the processing loop described above is activated and becomes loop-on, it starts the loop processing and measures the number of times. Click 1 on the counter area 96.

Here, it is assumed that the processing time for one loop has been measured in advance.

In the first method, the measurement is terminated in response to an operator inputting a termination command. This end command is sent to the message processing task 5 via the console processing task 6, and the message processing task 5 turns on the end flag of the measurement table 9. In the received message processing after turning on the end flag, the measurement end time is stamped in the measurement end time area 93 of the measurement table 9, the processing loop in the free time measurement area 7 is turned off, and then the δ1 calculation task 8 is activated.

In the second method, when the message processing counter area 95 becomes equal to the number of message processing commands area 94, the measurement end time is stamped in the measurement end time area 93, and after turning off the processing loop of the free time measurement task 7, This starts calculation task 8.

In this calculation task 8, 1llll from the measurement table 9.
Deriving the Ill timing, the measurement end time, the number of message processing counts, and the number of loop processing counts, respectively, and calculating the one message processing time and :+iti usage rate using a predetermined formula, and then passing it through console processing task 6. This calculation result is output to the console 3.

The calculation formulas in this case are shown in formulas (1) and (2).

Processing time for one message = ((t - t5) - L - n) 7
m... (1) it * Ifi usage rate = ((t - tS) - L - n
)/(1-15>...(2) Here, 11 is the measurement start time and the measurement path S l
e is the end time, L is the number of loop processing, m is the number of message processing, and n is the processing time required for one loop.

Figure 3 shows an example of a time chart from the perspective of interrupt priority levels for the line processing task, message processing task, and free time measurement task, with the line processing task having the highest priority and the free time measurement task having the lowest priority. It becomes.

Assuming that the start command has already been input, the line processing task 4 operates upon reception of the first message (a), and control is passed to the message processing task 5. In the message processing task 5, the idle time processing task 7 is started to activate the processing loop and the measurement start time is stamped (b). After processing the message, a response message is sent to the terminal in line processing task 4 (C).

At this time, the operation (d) of the free time measurement task 7 is performed while waiting for the completion of transmission. The line processing task 4 operates again due to the transmission completion interrupt (e) and starts the next message reception process.

When the final message is received (f) by an end command (first method) or by matching the number of message processing commands (second method), message processing task 5 stamps the end time with the end of message processing, and then returns to the processing loop. is turned off (g).

The total time of measurement from measurement start time ts to end time t8 is t. -1S, which also includes free time. This idle time is calculated by multiplying the number of loop processing times the processing time of one loop by 1-n. Checking the completion of marking of measurement start/end times, etc. becomes a measurement overhead, but it becomes a negligible value by increasing the number of messages to be processed.

Examples of implementation of the present invention are shown in FIGS. 4 and 5. FIG. 4 shows a system during online business execution, which is used mainly for the purpose of knowing how long calculation type 1 is being used, and corresponds to the first method of the present invention. still,
10 is a data file.

Figure 5 shows a system for transmitting and receiving cannabis telegrams from ts1 machine 11 via line 12 for the purpose of measuring the performance of the hardware and software of the instrument to be measured. Equivalent to. Good results can be obtained by matching the number of generated and processed messages.

Effects of the Invention According to the present invention, the processing time of one message can be measured with a value that allows the overhead time involved in the measurement to be ignored, and at the same time, the usage rate for each total n can be measured.
