DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed system for automatically transferring a failure log file from a server in a server / client system to a center device through a communication network and analyzing and grasping the content and cause of the failure in the center device. It relates to a processing error log automatic management system.

2. Description of the Related Art Conventionally, an NFS (Network File System) server / client system in a UNIX file sharing system or the like is sometimes constructed as a data communication network connected to a center device via a communication network.
In a data communication network including such a server / client system and a center device, data obtained when a client processes a part of a program in a server through a remote procedure call (RPC) is transmitted from the server to an N-ISDN or the like. Is transferred to the center device through a general subscriber line or a dedicated line.

As this data communication network, for example, processing data is collected by a host computer at the head office by data communication between a large number of branch offices (factories) scattered throughout the country and the head office, and a centralized processing for confirming normal operation is performed. Remote data communication networks for managing are well known. In addition, factory automation (FA) in factories
It is also well known as an in-house data communication network that transfers data from a computer as a server to a host computer through an in-house communication line and uses the host computer to perform unified production process management.

In such a remote / premise data communication network, when a failure is recognized by the server, a log of the server is used to confirm the failure status by the center device.
The recording file is being transferred to the center device. in this case,
The log record file of the server is transferred to the operation terminal device in the center device through the network, and only the fault log file (data) relating to the fault is extracted and displayed on a screen, and the status of the fault is checked by a network administrator or the like. Further, a failure log file relating to the failure is printed out and output in a list, and a failure status is identified from the list by a network administrator or the like.

As a conventional example of such a distributed processing system, an example disclosed in Japanese Patent Application Laid-Open No. 3-127352 is well known.
In this conventional example, a distributed processing computer executes a job for business processing according to an operation procedure sent from a host computer at predetermined intervals, and returns log information obtained by the execution to the host computer. From the log information, the business processing status of the distributed processing computer is managed so that an error in the operation procedure or execution can be detected at an early stage.

[0006]

However, in the above conventional example, when the server recognizes the occurrence of a failure, the server transfers a log recording file every time the failure is recognized, and
It is necessary to extract a failure log file from the log record file. Therefore, when a large number of servers are used, transfer of a log recording file that requires a long time for each server is executed, and a failure log file is extracted from a log recording file of a server / client system having a different data processing form. Work is required. In this case, there is a drawback that the failure at this time is often examined by referring to the log recording file transferred before, and the time required to check the failure status is increased.

[0007] In the conventional example of JP-A-3-127352,
The log information of the business process executed by the distributed processing computer according to the operation procedure instructed by the host computer is returned to the host computer. Therefore, even in this conventional example, when an error in the operation procedure or execution is detected from the log record file, there is a disadvantage that the time required for the confirmation work becomes long.

The present invention solves such a problem in the prior art, and automatically transmits only a failure log file to a center device in which a server / client system is connected by a communication line when a failure occurrence in a server is recognized. The transfer is now possible, eliminating the need to extract the error log file in the center unit, reducing the time required for checking the error status, and enabling the network administrator to easily and quickly check the error status.
