Abstract

PROBLEM TO BE SOLVED: To unnecessitate the correction of a recording means associating with the addition of a diagnostic module in the mechanism recording the error information by a device diagnostic program (module). SOLUTION: When each of diagnostic modules 1 to 4 successively performs a device diagnosis and detects an abnormality, the module performs the notification of the generation of an error including a module identification number and transmits error information to a log module 30. A logging processing part 31 performs a check as to whether the diagnostic module shown by the identification number is registered in a registration table 32 or not, registers the diagnostic module by making it correspond to an empty storage area number when the module is not registered, acquires the corresponding storage area number when the module is already registered and records error information (log information) in the corresponding storage areas 1 to 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagnostic program error information recording system.

[0002]

2. Description of the Related Art When a system control unit executes a diagnostic program for diagnosing normality / abnormality of a device, and if the target device has an abnormality (error occurrence), a corresponding error including a program sequence issued by the diagnostic program Information is recorded in a storage area of a storage device such as a magnetic disk so that the information can be referred to so that an early problem can be solved.

FIG. 3 shows an example of a conventional error information recording method. In FIG. 3, there are three diagnostic programs (hereinafter referred to as diagnostic modules) for which error recording is desired (diagnostic modules 1, 2, 3), and three storage areas for storing error information (area number 1, 2, 3) Yes. When recording error information (hereinafter referred to as logging), the error information (log 1) of the diagnostic module 1 is stored in the storage area 1.
The storage area 2 stores the error information of the diagnostic module 2 (log 2), and the storage area 3 stores the error information of the diagnostic module 3 (log 3). It corresponded fixedly. For example, when an error occurs in the diagnostic module 1, the module 1 notifies the logging module (log module) of the occurrence of the error and the content of the error. The log module, based on the fixed correspondence information between the recording area and the module registered in the table in advance,
The content of the error is recorded as a log 1 in the storage area 1 corresponding to the diagnosis module 1. After that, if an error occurs in the diagnostic module 3, the log module that has received the error notification records the error content as the log 3 in the storage area 3 corresponding to the diagnostic module 3 as before.

[0004]

In the conventional error information recording method, since a storage area for recording error information is fixedly assigned to each diagnostic module, a diagnostic module 4 is added as shown in FIG. When performing the above, a system maintenance person adds a storage area 4 for storing error information (log 4) of the diagnostic module 4 added in advance in the storage area, and a correspondence table between the storage area and the diagnostic module is created in the log module. It had to be corrected (addition of the correspondence between the storage area 4 and the module 4), and the maintainability was low.

[0005]

According to the error information recording method of a diagnostic program of the present invention, each device diagnoses the device and outputs an error occurrence notification including its own identification information and corresponding error information when there is an abnormality. Registering a plurality of diagnostic modules that are diagnostic programs, a storage area of a number smaller than the number of the diagnostic modules capable of recording error information of any of the diagnostic modules, and correspondence information between the storage areas and the diagnostic modules. Having a registration table, when receiving the error occurrence notification and the error information from the diagnostic module, the registration table is referred to, and when the diagnostic module identified by the identification information is already registered, the storage area associated with it is displayed. Get location information,
If the diagnostic module identified by the identification information is not registered, the association with the vacant storage area is registered, the position information of the storage area is acquired, and the storage area specified by the acquired position information is received. And a recording means for recording the error information.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. The diagnostic module unit 10 has a plurality of diagnostic modules 1, 2, 3, 4 that actually diagnose the device and output an error occurrence notification and error information when an error occurs. The error information storage area unit 20 has a plurality of storage areas 1, 2, 3 capable of storing error information (logs 1, 2, 3, 4) for each diagnostic module 1, 2, 3, 4 in a corresponding manner. are doing. The number of storage areas can be smaller than the number of diagnostic modules. The log module 30 receives the error occurrence notification and the error information from each of the diagnostic modules 1 to 4 and refers to the registration table 32 to check the corresponding storage area 1 to
Logging processing unit 3 for recording error information in any of 3
One. The registration table 32 stores the correspondence between the storage areas 1 to 3 and the diagnostic modules 1 to 4 in the logging processing unit 3.
It is possible to register as desired by 1.

Next, the operation will be described with reference to the flow chart of FIG. 2 together with FIG.

The diagnostic module section 10 is activated by turning on the power of the apparatus or by a diagnostic command by a maintenance person, and a series of apparatus diagnostics by the diagnostic programs 1 to 4 are executed. Prior to the execution, the log module 30 is executed. The registration contents of the registration table 32 therein are cleared (step S1 in FIG. 2). Although not shown, the diagnostic modules 1 to 4 each include an apparatus diagnostic program section that performs various functional tests and characteristic tests on the apparatus, and an error including identification information of the module itself when an error is detected by the apparatus diagnostic program section. It is composed of an error information processing unit that collects and outputs a notification of occurrence and detailed error information indicating error status, contents, and the like. The diagnostic modules 1 to 4 sequentially perform diagnostics (step S2), and if no error is detected (NO in step S3), the log module 30 does nothing. When an error is detected in any one of the diagnostic modules, for example, the diagnostic module 2, an error occurrence notification including its own diagnostic module number is issued to the log module 30.
And the error information is subsequently transmitted (step S4).

A logging processing section 31 of the log module 30.
Receives the error occurrence notification, refers to the registration table 32 (step S5), checks whether the diagnostic module as the output source of the error occurrence notification has already been registered (step S6), and if not registered, the storage area is empty. ,
For example, the number (module 2) of the diagnostic module 2 corresponding to the storage area 1 is registered (step S7). In the case where it has already been registered or after new registration, the logging processing unit 31 receives the error information received together with the error occurrence notification according to the registered contents of the registration table 32, and stores the corresponding error information in the error information storage area unit 20 (storage area). It is recorded in 1) as log information (log 2) (step S8). The processing from step S2 to step S8 is repeated until all scheduled diagnostic programs 1 to 4 are completed (step S9). In this way, for example, when an error is detected in the diagnostic module 4, the number (module 4) of the diagnostic module 4 is registered in the registration table 32 of the log module 30 corresponding to the storage area 2, and the error information storage area unit Error information corresponding to the storage area 2 in 20 is recorded as the log 4.

As described above, the storage areas 1 to 3 of the error information storage area unit 20 are set to the diagnostic modules 1 to 4, respectively.
Since the registration table 32 of the logging processing unit 30 can be registered by associating it with a free storage area only for the diagnostic module that generated the error information, The number of storage areas can be made smaller than the number of diagnostic modules in accordance with the error detection probabilities of all the diagnostic modules, and the usage efficiency of the storage capacity of the storage device can be improved. Further, since the registration of the correspondence information in the registration table 32 is based on the error occurrence notification from each diagnostic module 1 to 4,
When the diagnostic module is added or deleted, the system maintainer does not need to register or delete the corresponding information in the registration table, which improves maintainability. For example, even if a diagnostic module 5 (indicated by a dotted line in the figure) is newly added in the state of FIG. 1, there is still room in the storage area (and registration table) to record error information.

If the number of diagnostic modules for which an error has been detected exceeds the number of storage areas prepared in advance, an overflow is detected in the empty search process of the registration table 32 in step S7, and an output is output to notify that effect. No error information is recorded (diagnosis continues). Alternatively, when an overflow of the registration table 32 is detected, the logging processing unit 31 checks whether or not the storage area can be increased, and if the storage area can be increased, the registration capacity of the registration table 32 is increased by that amount to prevent the overflow. You can

[0012]

According to the present invention, since the association between the diagnostic modules and the storage area for recording the error information is variably performed automatically only when the error information occurs, the number of diagnostic modules can be reduced. The necessity of manually correcting the registration table in the recording means and expanding the storage area in the case of an increase is significantly reduced as compared with the prior art, and the maintainability is improved.
