Abstract

PURPOSE:To relieve the load on a communication control module and to improve the communication control capability by loading a communication fault monitor program to a computer independently of the communication control module. CONSTITUTION:A communication fault monitor program 300 extracts information from a LAN controller 301 and information 311 from a communication control module 302 and records a data 312 after edit to an external storage device 303. Moreover, the program 300 reads a relevant edit data 313 from the device 303 according to a command 314 from a keyboard 304 and outputs and displays a display data 315 onto a CRT 305. Thus, the program 300 separates a function possessed to the communication control module 302 to make it independent as a program for communication fault monitor thereby enhancing the function. Thus, the overhead of the module 302 is relieved and the communication control function is enhanced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication failure monitoring system in a LAN.

0002

2. Description of the Related Art Conventionally, fault monitoring in a LAN has been carried out by including a function for collecting line tracing, logging, etc. in a communication control program to control communication.

0003

[Problems to be Solved by the Invention] In the conventional communication failure monitoring method described above, since the communication control module includes a communication failure monitoring function, the overhead of the communication control module increases and the normal communication control ability is reduced. There is.

0004

[Means for Solving the Problems] A first aspect of the present invention is a communication failure monitoring method in a LAN connecting a plurality of computers, including a line tracing means for tracing communication data independently of a normal communication control means; comprising a logging collection means for tracing the operating state of the communication control means, a line quality information collection means for collecting line quality information, and a memory dump collection means for collecting memory dump information,
External storage recording means for recording information collected by the various means in a pre-equipped external storage device; and display for displaying the information recorded in the external storage recording means on a pre-equipped CRT display. It is characterized by having a means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a system including the present invention. FIG. 1 is a diagram showing a case where a sending computer (100) and a receiving computer (101) are connected via a LAN (106), and each computer is connected to a communication control module (102, 103) separately from communication failures. A monitoring program (104, 105) is implemented.

As shown in FIG. 2, the communication failure monitoring program (200) includes a line trace collection function (201) that collects line trace data on the LAN, and a communication fault monitoring function (201) that collects information such as the status of the communication control module and connection status. Control module logging collection function (202), line quality information collection function (203) that collects information such as transmission and reception errors and the number of times of transmission and reception in the LAN, and memory dump collection function (203) that collects a memory dump when a failure occurs.
04).

FIG. 3 shows the operating environment of the communication failure monitoring program. The communication failure monitoring program (300)
Information (310) from the LAN controller (301) and information (311) from the communication control module (302)
) and record the edited data (312) in an external storage device (303). In addition, the communication failure monitoring program retrieves the corresponding edited data (313) from the external storage device (303) according to the instruction (314) from the KB (304).
The display data (315) is output to the CRT (305) and displayed on the screen.

As mentioned above, the communication failure monitoring program
This program separates the functions previously held by the communication control module and creates an independent communication failure monitoring program with enhanced functionality. Therefore, since there is no overhead load on the communication control module as in the conventional case, the original communication control ability is improved.

[0010] Also, the function of the communication failure monitoring program is as follows:
It should be made optional by the command from , and it should be extensible so that functions other than the four functions of line trace collection function, communication control module logging collection function, line quality information collection function, and memory dump collection function can be added. becomes easier.

[0011]

[Effects of the Invention] As explained above, the present invention has the effect of reducing the load on the communication control module and improving communication control ability by implementing a communication failure monitoring program in a computer independently of the communication control module. There is. Furthermore, there is an effect that activation control of each function of the communication failure monitoring program and addition of functions are facilitated.
