[Industrial applications]

The present invention relates to a logging information storage system by occurrence frequency,
More specifically, in various computer systems, it is used to store various logging information such as operation information and error information for the purpose of knowing the occurrence and restoration of failures, etc., and important logging information is destroyed and disappears. The present invention relates to a logging information storage method for each occurrence frequency that can prevent the above.

[Conventional technology]

Conventionally, in general, in various computer systems, in many cases, various logging information such as error information is stored in a logging file in order to know operation information, failure occurrence, and recovery.

FIG. 3 is a diagram showing such a conventional logging information storage method.

Reference numeral 50 is a main control unit (CPU) that controls the overall operation, 51 is a task processing unit that processes various tasks, 52 is a logging stack buffer that temporarily stores logging information, and 53 is a logging file.

The logging information from the task processing unit 51 is temporarily stored in the logging stack buffer 52, and then sequentially stored in the logging file at a fixed cycle.

In this case, the logging stack buffer 52 is a memory having a relatively small capacity, and sequentially stores all the logging information together.

Then, when the logging information exceeding the memory capacity of the logging stack buffer 52 is continuously sent, the previous data is erased and new data is written.

In this way, the data in the logging stack buffer 52 is transferred to the logging file 53 and stored at a fixed cycle, but if the data cannot be stored in the logging stack buffer 52 before the data is transferred to the logging file 53. When the logging information of is sent, the previous data is destroyed and disappears.

[Problems to be Solved by the Invention]

The conventional device as described above has the following drawbacks.

That is, the logging information includes multiple logging information that occurs once and then repeats thereafter.

Due to this multiple logging information, other important logging information may be crushed, which has a drawback of hindering failure investigations.

The present invention eliminates such conventional drawbacks, prevents other important logging information from being crushed and disappears due to the multiple logging information, and makes it possible to accelerate the investigation of the cause of an error. With the goal.

[Means for solving the problem]

In order to achieve the above object, the present invention is as follows.

FIG. 1 is a principle diagram of a logging information storage system according to occurrence frequency according to the present invention.

Various tasks are processed by the task processing unit 2 according to an instruction from the main control unit (CPU) 1.

At that time, various kinds of logging information are generated, and the type of the logging information is judged in the logging information judging unit 3 in the task processing unit 2.

That is, once generated, multiple logging information that repeatedly occurs after that and other general logging information are classified into two types.

The general logging information sent from the logging information determination unit 3 is temporarily stacked in the general logging stack buffer 4 and then stored in the logging file 5 according to an instruction from the main control unit 1.

Further, the multiple logging information sent from the logging information determination unit 3 is temporarily stacked in the multiple logging stack buffer 6 and then stored in the logging mask buffer 8 via the multiple logging information control unit 7 at a predetermined cycle. be registered.

In the logging mask buffer 8, the frequency (number of times) of occurrence is registered together with the frequent logging information, these are read at a predetermined cycle and transferred to the general logging stack buffer 4, and then to the logging file 5. Store.

As described above, when the logging information generated in the task processing unit 2 is stored in the logging file 5, the general logging information and the frequent logging information are temporarily stacked in different buffers.

Of this multiple logging information, what repeatedly occurs is defined as frequent logging information, and what repeats in an ON-OFF group is defined as frequent logging information.

When the occurrence frequency is stored together with the frequent logging information, the frequent logging information registers the information and the number of occurrences, and the frequency logging information counts and registers the information and the number of ON-OFF pairs.

[Action]

With the above configuration, the multiple logging information does not destroy other important logging information and disappear.

Further, since the multiple logging information stores the information and the occurrence frequency (number of times), it is useful for investigating the cause of the failure.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram of an occurrence frequency-based logging information storage system according to an embodiment of the present invention, and the same reference numerals as those in FIG.

Reference numeral 1 is a main control unit (CPU), 2 is a task processing unit, and a logging information determination unit 3 is provided therein.

Reference numeral 4 is a general logging stack buffer, 5 is a logging file, 6 is a multiple logging stack buffer, 7 is a multiple logging information control unit, and a timer 9 is provided therein.

Reference numeral 8 is a logging mask buffer having a multiple logging information memory unit 11 and an occurrence frequency memory unit 10.

In response to an instruction from the main control unit 1, the task processing unit 2
Various task processes are performed, and various logging information is generated in the process.

This logging information is judged by the logging information judging section 3 and is classified into two types: general logging information and multiple logging information.

This determination is made in advance with respect to the logging information determination unit 3.
This is done by setting the data that serves as the criterion.

When the information sent from the logging information determination unit 3 is the multiple logging information, it is temporarily stacked in the multiple logging stack buffer 6 and then in the general logging stack buffer 4.

The general logging information stacked in the general logging stack buffer 4 is transferred and stored in the logging file 5 at a predetermined cycle according to an instruction from the main control unit 1.

The multiple logging information stacked in the multiple logging stack buffer 6 is sent to the multiple logging information control unit 7 in a predetermined cycle, and the information in the logging mask buffer 8 is referred to so that the registered information is not registered. See what.

If the information is not registered, the multiple logging information is registered in the multiple logging information memory unit 11, and the occurrence frequency 1 is registered in the portion of the occurrence frequency memory unit 10 corresponding to the information.

If the information is already registered, it is not registered in the multiple logging information memory unit 11, but the occurrence frequency in the occurrence frequency memory unit 10 corresponding to the information is counted up by +1 and re-registered. .

In this case, the frequent logging information includes frequent logging information that repeats occurrence and frequent logging information that repeats in an ON-OFF set.

Therefore, the frequent logging information registers the information and the number of times of occurrence, the frequency logging information updates the logging code to the latest, and counts and registers the number of ON-OFF pairs.

When the above operation is repeated and a predetermined time has elapsed, the timer 9 times out.

When the multiple logging information control unit 7 detects the time-out, the multiple logging information registered in the multiple logging information memory unit 11 in the logging mask buffer 8 is registered in the occurrence frequency memory unit 10. Examine the information whose occurrence frequency is not zero.

As a result, for information whose occurrence frequency is not 0, the data of the information and the occurrence frequency is transferred to the general logging stack buffer 4, and further transferred to the logging file 5 for storage.

This data transfer is controlled by the main control unit 1 so as to be performed separately from the general logging information.

When the frequent logging information and the data of the occurrence frequency are transferred from the logging mask buffer 8 to the general logging stack buffer 4 in this manner, the timer 9 is reset and restarted.

When the timer 9 times out again, data transfer is performed in the same manner as above, and this operation is repeated.

In the above case, if the occurrence frequency registered in the occurrence frequency memory 10 is 0, nothing is done.

〔The invention's effect〕

As described above, the present invention has the following effects.

(1) General logging information and frequent logging information are
Once stacked in separate buffers, the frequent logging information does not destroy other important logging information in a short time and disappear.

Therefore, even in the event of a failure, old logging information that was the root cause can be left behind, and failure investigations and the like are not hindered.

(2) Since the occurrence frequency (occurrence number) of the multiple logging information is counted, it is possible to know how often these logging information occurred, and to promote the investigation of the cause at the time of failure.
