Abstract

PURPOSE:To ensure a smooth operation of an on-line system by detecting a telegram sent through a circuit which secures the connection between the system and a terminal and calculating the response time of the system based on the report information on the detection of the telegram. CONSTITUTION:A telegram detecting device 11 detects a telegram sent to a circuit and informs a measuring device 12 of the input and output telegrams respectively. The device 12 starts the counting action of a measuring counter after the report of an input telegram detection signal. When this signal is reported, the counting action is discontinued and the count value is sent to an arithmetic unit 13. The unit 13 processes the received counter value and calculates the average counter value at a fixed time interval. Then the unit 13 calculates the response time of an on-line system 3 and sends this response time to a display device 14 and also informs the operator, etc., of the system 3 of the response time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that measures and calculates, in real time, the response time of a system to a message input from a terminal in an online system.

[Conventional technology] In online systems, it is important to guarantee response time, but with conventional technology, the means to measure response is based on data that records communication status with terminals, etc. Response time was calculated using offline processing.

[Problems to be Solved by the Invention] In the prior art, there was no means to measure line response time in real time, so it was not possible to measure and display terminal response time in real time. For this reason, the system has the disadvantage that it is not possible to immediately determine and execute measures to deal with delays in system response (for example, reducing services by blocking specific services to maintain the smoothness of the entire system). there were.

In the present invention, in an online system, the response time of the system to a message input from a terminal is measured, the system response time can be accurately grasped in real time, and this result is used as a feedbank to ensure smooth operation of the online system. The purpose is to

[Means for Solving the Problems] In the present invention, in order to make it possible to grasp the response time in real time, a message detecting means for detecting a message flowing on a line connecting a system and a terminal and notifying the message is provided. (telegram detection device 11), and a measuring means (measuring device 12) that measures the time from the time the message is input to the time the message is outputted using a measurement counter based on the notification information of the message detection in accordance with the line, and notifies the measured value. , is realized by a calculation means (calculation device 1113) that calculates the response time of the online system based on the measured value.

[In a working online system, for a terminal connected to the system via a communication line, the message detection means detects the input and output points of the message transferred on the line corresponding to the line, and detects the detected input and output. Using the time as a trigger, the measurement means starts and ends time measurement to obtain a measurement value corresponding to the line. Furthermore, the calculation means calculates the required terminal response time based on the measured values obtained for each line. Furthermore, since each line has a message detection device, it is possible to accurately measure the response time of the system's terminals without causing any disturbance to the online system.

The message detection device 11 detects a message transmitted over the line, and notifies the measurement device 12 of the message to the input message/output message side. The measuring device 12 that has received the notification has a time counter corresponding to the line, and starts counting the measurement counter when it is notified of the input sentence detection signal. This count is counted up in fixed time units (for example, 1 millisecond). When notified of the output message detection signal, it stops counting and transfers the 20 counter value to the arithmetic unit 13. In the computing device 13,
This counter value is processed and an average value at a fixed time interval is calculated. Arithmetic device 13 transfers this counter value to display device 14 . The display device 14 displays this counter value and notifies the driver of the system 3 and the like.

Notify. When the detection information notification bag 2113 receives a notification from the input message detection device 111 or the output message detection device 112, it detects the input message.
The output message detection side notifies the measuring device 12 of the line number information and the identification information of the input message/output message (for example, the identification information of the input message is A, and the identification information of the output message is B).
