Abstract

PURPOSE:To start the collection processing of a log data concerning the next fault even while fetching a log data concerning a first fault by parallelly executing the log data collection processing and the log data fetching processing. CONSTITUTION:When the plural faults are continuously generated in a data processor 1 and the log data fetching processing is not completed yet in a log data output device 8 in the case of completing the log data collection processing in a diagnostic controller 2, the log data fetching requiring information is tentatively stored so as to wait for the end of the log data fetching processing. Then, when the log data fetching processing is completed, the log data fetching requiring information is taken out so as to inform the log data fetching requirement to the log data output device 8. Thus, since the log data collection processing can be executed regardless of the log data fetching processing, the collection processing of the log data concerning the next fault can be started even while fetching the log data concerning a certain fault.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to failure handling in a data processing device, and particularly to a log data collection method when a failure occurs in a data processing device.

[Conventional technology]

Conventionally, in this type of log data collection method, when a failure occurs in a data processing device, a diagnostic control device collects log data from the data processing device as part of failure handling.
The collected log data was imported from the diagnostic control device to the log data output device.

By the way, in the conventional log data collection method, the capacity of the log data storage unit installed in the diagnostic control device was only large enough to collect log data related to one failure, so if multiple failures occurred in succession in the data processing device, If this occurs, the diagnostic control device collects log data from the data processing device, notifies the log data output device of a log data import request, and the log data output device collects the log data from the diagnostic control device. By performing the data import process, log data related to the first failure is collected, but before starting the log data collection process related to the next failure, the log data output device must finish the log data acquisition process related to the first failure. Therefore, the log data collection process for the next failure cannot be started until the log data capture process for this first failure is completed, and the log data collection process is temporarily suspended and the log data for the first failure is Waiting for data import processing to finish.

[Problem to be solved by the invention]

In the conventional log data collection method described above, the capacity of the log data storage section provided in the diagnostic control device was only large enough to collect log data related to one failure, so the collected log data is not output as log data. Log data collection processing related to failures that occur while being imported into the device must wait for the end of the log data acquisition process on the log data output device before starting, which may cause multiple failures to occur in succession. In this case, the log data collection process for the log data related to the next failure that occurred cannot be performed until the log data import process for the previously collected log data is completed. In view of this, we have developed a log system that allows log data collection processing in the diagnostic control device and log data import processing in the log data output device to be performed in parallel even if multiple failures occur in succession in the data processing device. The objective is to provide a data collection method.

[Means to solve the problem]

The log data output device includes a data import section and a log data import end notification section that notifies the diagnostic control device that the log data import process by the log data import section has ended.

[Effect]

In the log data collection method of the present invention, the log data storage section can store a plurality of pieces of log data of a data processing device for each failure, and the log request information storage section stores the collected log data in the log data storage section. Multiple pieces of log data import request information to be imported into the output device can be accumulated, the failure processing control unit detects the occurrence of a failure in the data processing device, and the logout control unit detects the failure of the data processing device by the failure processing control unit. The log data of the data processing device is collected in the log data storage unit when the occurrence of the log data is detected, and the log data acquisition waiting control unit collects the log data in the log data storage unit when the logout control unit completes the log data collection process to the log data storage unit. If the log data import process on the data output device has not finished, log data import request information is accumulated in the log request information storage unit, waits for the log data import process on the log data output device to finish, and the log data Upon receiving the log data import completion notification from the output device, the log data import request information regarding the next failure that occurred is retrieved from the log request information storage unit, the log data import request is notified to the log data output device, and the log data import unit Upon receiving a log data capture request from the diagnostic control device, the log data capture device captures the log data from the diagnostic control device, and the log data capture completion notification unit notifies the diagnostic control device that the log data capture process by the log data capture unit has ended.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a data processing system to which a log data collection method according to an embodiment of the present invention is applied. This data processing system consists of a data processing device 1 in which a fault occurs, a diagnostic control device 2 that collects log data from the data processing device 1 in which a fault occurs and controls fault processing, and a diagnostic control device 2. From a log data output device 8 that takes in the collected log data,
Its main parts are composed of:

The inter-diagnosis m device 2 includes a failure processing control section 3, a logout control section 4, a log data acquisition waiting control section 5, a log data storage section 6, and a log request information storage section 7. .

The fault processing control unit 3 detects the occurrence of a fault in the data processing device 1 and performs a series of fault processing including log data collection processing.

The logout control section 4 sequentially collects log data of the data processing apparatus 1 into the log data storage section 6 when the occurrence of a failure in the data processing apparatus 1 is detected by the failure processing control section 3 .

If the log data capture process in the log data output device 8 has not been completed at the time the logout control unit 4 finishes collecting log data in the log data storage unit 6, the log data capture queue control unit 5 , accumulates the data import request information in the log request information storage unit 7, waits for the end of the log data import process in the log data output device 8, and upon receiving the log data import completion notification from the log data output device 8, the log request is completed. The log data retrieval request information regarding the failure that occurred first is retrieved from the information storage unit 7 and the log data retrieval request is notified to the log data output device 8.

The log data storage unit 6 is capable of storing a plurality of pieces of log data for each failure when a failure occurs in the data processing device 1.

The log request information storage unit 7 is configured to import log data to cause the log data output device 8 to import the log data collected in the log data storage unit 6 when a plurality of failures occur in succession in the data processing device 1. Multiple pieces of request information can be stored.

The log data output device 8 includes a log data capture section 9 and a log data capture completion notification section 10.

Upon receiving a log data import request from the diagnosis I+ll1II device 2, the log data import unit 9 imports the log data from the diagnostic control device 2.

The log data capture completion notification unit IO notifies the diagnostic control device 5 that the log data capture process by the log data capture unit 9 has ended.

Referring to FIG. 2, the processing in the diagnostic control device 2 is as follows:
A failure occurrence notification reception step 201, a log data collection process 202, a capture flag determination step 203, a waiting process generation step 204, a log data capture request information accumulation step 205, and a capture wait counter energizing step 206. , a waiting step 207 , a capturing flag determining step 208 , a log data capturing request information extraction step 209 , a capturing wait counter subtraction step 210 , and a capturing flag on step 211
, log data import request notification step 212 , log data import end notification reception step 213 , import flag off step 214 , import waiting counter determination step 215 , and queue process disappearance step 216
It consists of.

Next, the operation of the log data collection method of this embodiment configured as described above will be explained. Here, referring to FIG. 3, it is assumed that the log data collection process in the diagnostic control device 2 regarding the next failure ends before the log data capture process in the log data output device 8 regarding the first failure ends. This will be explained by taking a case as an example.

When a failure occurs for the first time in the data processing device 1, the data processing device 1 notifies the diagnostic processing device 2 of the occurrence of the failure.

In the diagnostic control device 2, when the fault processing control section 3 receives the fault occurrence notification from the data processing device 1 (step 20
1) Instruct the logout control unit 4 to collect log data.

The logout control unit 4 starts log data collection processing in response to a log data collection instruction from the failure processing control unit 3, and stores log data related to the first failure from the data processing device 1 where the failure has occurred to the log data storage unit 6. Collect step 2
02), the location information of the log data related to the first failure stored in the log data storage unit 6 (hereinafter referred to as the log data storage address) is passed to the log data acquisition queue control unit 5.

The log data capture queue control unit 5 first determines whether the capture flag is on or off (step 203), and since the capture flag is initialized to OFF when a failure occurs for the first time, it generates a queue process (step 203). Step 204
), then the log data capture queue control unit 5 turns on the capturing flag (step 211) and notifies the log data output device 8 of a log data capture request including the log data storage address (step 212).

In the log data output device 8, the log data import unit 9
When a log data import request is received from the diagnostic control device 2, a log data import process is started, and the log data related to the first failure specified by the log data storage address is downloaded from the log data storage unit 6 of the diagnostic control device 2. Start importing.

If the next failure occurs in the data processing 1 while the log data related to the first failure is being captured in the log data output device 8, the data processing device 1 sends the diagnostic processing device 2 is notified of the occurrence of the failure.

In the diagnostic control device 2, when the fault processing control unit 3 receives the fault occurrence notification from the data processing device 1 (step 20
1) Instruct the logout control unit 4 to collect log data.

The logout control unit 4 starts log data collection processing in response to a log data collection instruction from the failure processing control unit 3, and converts the log data related to the next failure from the data processing device 1 where the failure occurred to the log data related to the first failure. In step 202), the log data storage unit 6 is collected at a different address from the log data storage address of the log data storage unit 6.
The log data storage address of the log data related to the next failure stored in is passed to the log data acquisition waiting control unit 5.

The log data retrieval queue control unit 5 determines whether the retrieval flag is on or off (step 203), and since the retrieval flag is on, the log data retrieval request information including the log data storage address is sent to the log request. Step 205) to accumulate in the information storage unit 7, and the acquisition waiting counter (
After adding 1 to the initial value 0 (step 206) and waiting for a certain period of time (step 207), since the importing flag is on (step 208), step 20
7 and 208, the loop is repeated, that is, the end of the log data capture process in the log data output device 8 is awaited.

It goes without saying that even if the next failure occurs in the data processing device 1 after this, the operation will be the same as the case when the next failure occurs as described above.

Therefore, the log data storage unit 6 of the diagnostic control device 2 sequentially stores log data equal to the number of failures that have occurred after the first failure, and the log request information storage unit 7 stores log data that corresponds to the number of failures that have occurred after the first failure. The number of log data acquisition request information is accumulated, and the number of stored and accumulated log data and log data acquisition request information is counted in an acquisition waiting counter.

In this state, when the log data capture process related to the first failure is completed in the log data output device 8, the log data capture unit 9 notifies the log data capture completion notification unit 10 to that effect, and the log data capture completion notification unit IO , notifies the diagnostic control device 2 that the log data acquisition is complete.

In the diagnostic control device 2, the log data acquisition waiting control section 5
When the log data capture completion notification is received from the log data output device 8 (step 213), the capture flag is turned off (step 214), and the capture wait counter is set to O.
(step 215). In this case, since the capture wait counter is not 0, control enters the waiting process, and steps 207 and 2 that were waiting are executed.
Exit the loop of 08. As a result, the log data retrieval queue control unit 5 retrieves the earliest (next) log data retrieval request information from the log request information storage unit 7 (step 209), subtracts one from the retrieval wait counter (step 210), Then, the log data import waiting control section 5
After turning on the capture flag again (step 21),
1) Notify the log data output device 8 of a log data import request (step 212).

As a result, in the log data output device 8, the log data import unit 9 starts the log data import process again, and receives the next log data specified by the log data storage address from the log data storage unit 6 of the diagnostic control device 2. Start importing.

After this, even if another failure occurs in the data processing device 1, the operation will be the same as that in the case of the next failure as described above.

When the log data output device 8 completes the log data capture process related to the next failure, the log data capture unit 9 notifies the log data capture completion notification unit IO to that effect, and the log data capture completion notification unit IO 2 is notified of the completion of log data import.

In the diagnostic control device 2, the log data acquisition waiting control section 5
When the log data capture completion notification is received from the log data output device 8 (step 213), the capture flag is turned off (step 214), and the capture wait counter is set to 0.
Otherwise (step 215), control is passed again to the queuing process.

By repeating the above steps, when the log data import process related to the last failure that has occurred is completed with the log data output value W8, the log data import waiting control unit 5 in the diagnostic control device 2 receives the log data import completion notification (step 213). ), turn off the capture flag (step 214)
, it is determined that the capture wait counter is 0 (step 215). Therefore, the log data capture queue control unit 5 eliminates the queue process (step 216).
), completes the collection of a series of log data.

In this way, in this embodiment, even if a plurality of failures occur in succession in the data processing device 1, the diagnostic control device 2 uses the waiting process to wait for the end of the log data capture process in the log data output device 8. By doing this, processing the log data import requests related to the failure one by one, and repeating this until there are no more log data import requests.
Log data can be sequentially imported into the log data output device 8.

〔Effect of the invention〕

As explained above, in the present invention, when a plurality of failures occur consecutively in a data processing device, when the log data collection process is finished in the diagnostic control device, the log data capture process is not finished in the log data output device. If the log data import request information is temporarily stored and waits for the completion of the log data import process on the log data output device, and when the log data import process is completed, the log data import request information is retrieved and the log data is By notifying the data output device of the log data import request, log data collection processing and log data import processing can be performed independently, without having to be aware of the log data import processing on the log data output device. Because log data collection processing can be executed,
Even during log data acquisition processing for a certain failure, log data collection processing for the next failure can be started without having to wait until the log data acquisition process is finished, which has the effect of speeding up the log data collection processing. .
