Abstract

PURPOSE:To automatically collect line fault information and to eliminate a person's intervention and an information loss by starting automatically a trace collecting program by a program starting part, when a status deciding part has detected a fault. CONSTITUTION:When communication is started through a communication line, a synchronous or asynchronous status is informed to a communication control program 22A from a communication controller 1. A status deciding part 22C obtains this synchronous or asynchronous status, and decides whether a fault has been generated in the line or not. When the generation of a fault has been detected, it is informed to a program starting part 22D, and the starting part 22D starts a trace collecting program 22B. The program 22B reads trace information from the controller 1 through the program 22A. Subsequently, by editing this information, a trace file is generated, and it is outputted to a disk device 5.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is an automatic line failure information system that automatically collects line failure information when a computer system that communicates via a communication line detects a line failure. This concerns the collection method.

[Conventional technology]

A conventional line failure information collection method will be explained based on FIG.

FIG. 3 is a system configuration diagram for explaining the conventional collection method. In the figure, 1 is a communication control device, 2 is a computer main body, 3 is a display device (referred to as C and RT), 4 is a keyboard, and 5 is a It is a disk device.

Inside this computer main body 2 is a central processing unit (CPU) 21.
and a memory 22.

Also stored in this memory 22 are a communication control program 22A that controls the communication control device 1, and a trace collection program 22B that traces line failure information and creates a trace file when a line failure occurs.

Next, the operation will be explained.

Assume that the computer main body 2 is now communicating with another computer system via the communication control device 1 according to the communication control program 22A.

If a fault occurs in the line, information indicating the line fault is displayed on the CRT 3, and the operator operates the keyboard 4 to start the trace collection program 22B. The trace collection program 22B reads the trace information of the communication control device 1 through the communication control program 22A, edits it, creates a trace file, and stores it in the disk 5.

[Problem to be solved by the invention]

Since the conventional line failure information collection method was configured as described above, the operator had to constantly monitor the line status, and when the trace collection program was started, the trace area of the communication control device was moved to another area. There was a problem that the information was changed and the fault information was sometimes lost.

This invention was made to solve the above-mentioned problems, and an object thereof is to provide a method for automatically collecting line failure information.

[Means to solve the problem]

A status determining section 22G that monitors the status of the communication control device 1 according to the present invention and determines a failure based on the status, and a program starting section 22D that starts the trace collection program 22B, and the status determining section 22C detects a failure. This feature is characterized in that when detected, the trace collection program 22B is automatically started by the program starting section 22D.

[Effect]

The status determination unit 22C in this invention monitors the status of the communication control device 1. When a line failure is detected from this status, the program starting unit 22
D automatically starts the trace collection program 22B. Here, the trace collection program 22B traces information on line failure.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. Note that the same components as those in the prior art are given the same numbers and their explanations will be omitted.

FIG. 1 is a configuration diagram showing an embodiment of the present invention, in which 22C is a status determination unit that monitors the status of a communication control device and determines a failure from this status; 22D;
is a program starting section that starts the trace collection program 22B.

Next, the operation will be explained with reference to the operation flowchart shown in FIG.

When communication is started via the communication line (step Sl),
The communication control device 1 notifies the communication control program 22A of the synchronous or asynchronous status. The status determination unit 22C obtains this synchronous or asynchronous status (step S2). Then, it is determined from this status whether a failure has occurred in the line (step S3). If no failure has occurred, the process returns to step S2 to obtain the next status. On the other hand, when a failure has occurred, this is notified to the program starting unit 22D, and the program starting unit 22D starts the trace collection program 22B (step S4). The trace collection program 22B reads trace information from the communication control device 1 through the communication control program 22A (step S5). This information is edited to create a trace file, which is output to the disk 5 (step S6), and the process ends.

In addition, in the above embodiment, a method was explained in which a trace collection program is started and a trace file is created.However, even if the trace area of the communication control program is output to a file when a line failure is detected, the above embodiment also applies. It has the same effect as.

[Effects of the Invention] As explained above, according to the present invention, a status determination unit that monitors the status of a communication control device and determines a failure based on this status, and a program startup unit that starts a trace collection program are provided. When the status determination section detects a fault, the trace collection program is automatically started by the program starting section, so line fault information is automatically collected, so there is no need for operator intervention. Further, there is an effect that failure information is not lost.
