Abstract

PURPOSE:To allow the classification to have versatility, and also, to cope with the change of the classification by setting a part of log data as general log data, and collecting not only fundamental log data but also designated general log data. CONSTITUTION:When a write request is given from a computer, a log data collection processing part fetches fundamental log data from the computer and stores it in a log data storage part 5. In this case, it is stored in the funda mental log data area 11i2 of an unused block 11i instructed by a pointer in accordance with the contents of a management table 10. Subsequently, the general flag area 10a of the table 10 is checked, and when a flag is set, the classification of general log data stored in a classification area 10b is fetched, and log data is fetched from the computer and stored in the storage part 5. In this case, this data is stored in the log data area 11i3 of the unused block 11i instructed by the pointer, based on the contents of the table 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for collecting log data, and in particular, is intended to provide flexibility in the types of log data to be collected.

[Prior Art] For example, in a so-called mini computer system, in order to perform failure analysis of this mini computer system,
Data that can be used for failure analysis (hereinafter referred to as log data) such as register data, counter data, abnormality detection sensor data, and part of memory data inside the minicomputer main body is periodically collected. or when a predetermined collection condition is met, the log data is transferred to the log data storage unit (hereinafter, this transfer is referred to as log data collection). In other words, when a failure occurs,
Failures in the minicomputer system are analyzed by analyzing multiple sets of time-series log data collected in the log data storage unit.

FIG. 2 shows a functional block diagram of a conventional log data collection method, and FIG. 3 shows the structure of the log data storage section 4. As shown in FIG.

In FIG. 2, the user uses the keyboard input device 1 to instruct the log data collection processing section 2 to set the log data collection mode.

The log data collection processing section 2 has a microprogram configuration and is originally provided within the computer main body 3, but in FIG. 2, it is shown separately from the computer main body 3 from a functional standpoint. There is. When the log data collection mode is set, the log data collection processing section 2 notifies the computer main body 3 of this fact.

After the computer main body 3 is instructed to enter the log data collection mode, the computer main unit 3 periodically or when predetermined collection conditions are not met,
The log data collection processing unit 2 is caused to execute collection processing. That is, the log data collection processing section 2
The data at that time is taken out as log data from a predetermined register, counter, sensor, or part of the memory, and is given to the log data storage section 4 and written.

Note that the log data storage section 4 is also one that is originally provided inside the computer main body 3 (for example, a main storage device).
However, in FIG. 2, it is shown separately from the computer main body 3 from a functional standpoint.

The log data storage unit 4 has a structure shown in FIG. That is, it manages a plurality of blocks 4a to 4n to which identification data are attached for storing log data collected in a single collection, and whether the blocks are stored or unstored, and also manages the collected log data. In this way, when log data is given, the log data is stored in the unstored block having the next identification data after the identification data of the last stored block. Until the end of the log data collection mode is instructed from the keyboard input device 1, log data is collected and stored in the log data storage unit 4 periodically or every time a collection condition is met.

[Problems to be Solved by the Invention] According to the conventional method, the type of log data to be collected is fixedly determined by the configuration of the log data collection processing section 2.

However, after starting to use the minicomputer system, the user may want to change the log data collected. For example, when performing a failure analysis, it may be desirable to include other data in the log data, or log data that cannot be used for the desired failure analysis may be collected.

Furthermore, although some registers and the like in the computer main body 3 are designed to be freely usable by the user, it has not been possible to log the data of such registers and the like.

In order to solve this problem, the log data collection processing section 2 must be newly configured. Also, it is possible to increase the types of log data from the beginning to ensure that the necessary log data can be collected, but this would result in a lot of useless log data being included, and the log data It is necessary to use a large capacity storage unit 4.

The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a method for collecting log data that is flexible in types of log data and can easily respond to changes in types.

[Means for Solving the Problems] In order to solve the problems, the present invention collects a plurality of log data and stores them in the log data storage unit once or more at a predetermined timing on the time axis. The method for repeatedly collecting log data was as follows.

That is, multiple log data are divided into basic log data that is fixedly determined and general-purpose log data that can be selected by input operation, and before the start of collection, the selected general-purpose log data is imported and the basic log data and ill Depending on the amount of general-purpose log data selected, the log data storage unit is divided into blocks that can separately store collected log data each time, and the basic log data and general-purpose log data collected each time are stored as log data. It is now stored in an unused block.

[Operation] Some log data to be collected may be left to the user's discretion. Therefore, we have decided to divide the types of log data into basic log data, which must be collected, and general-purpose log data, which can be selected by the user through input operations. Then, before starting collection, the type of general-purpose log data entered by the user is imported. Here, the amount of log data stored in one collection operation changes depending on the selected general-purpose log data, so the amount of log data collected in one operation depends on the basic log data and the selected general-purpose log data. Create blocks to store data.

After such preprocessing, log data collected periodically or when collection conditions are met is sequentially stored in unused blocks.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Here, FIG. 1 is an explanatory diagram showing the structure of the log data storage unit in this embodiment, FIG. 4 is a flowchart showing preprocessing for log data collection, and FIG. 5 is a flowchart showing log data collection processing. be.

The functional configuration of this embodiment is also similar to the conventional configuration shown in FIG. In this embodiment, the code 5 is used for the log data storage section, and the same codes 1 to 3 as in the past are used for the other functional blocks.

However, in the case of this embodiment, the log data that can be collected is divided into fixed basic log data and general-purpose log data that can be selected arbitrarily by the user.
The log data collection processing unit 2 simultaneously collects basic log data and general-purpose log data in one collection operation.

Here, what made it possible to collect general-purpose log data is that the computer main body 3 is equipped with general-purpose registers, counters, etc. that the user can freely use. This is because it may be desired to collect data as log data.

Next, the structure of the log data storage section 5 will be explained using FIG.

In FIG. 1, the log data storage unit 5 includes a management table unit 10 and a plurality of blocks lla, 11b, . . . lln that store a group of log data collected in one collection operation.
It becomes.

Each block lla to lln has a block identification data area 11a that stores data identifying the block.
1 to 11n1, basic log data areas 11a2 to 11n2 for storing basic log data, and general-purpose log data areas 11a3 to 11n3 for storing general-purpose log data collected when general-purpose log data is specified.

The management table unit 10 includes a general-purpose flag area 10a that stores a flag indicating whether or not general-purpose log data is collected.
, the general-purpose log data type area 10b that stores the type of general-purpose log data, the addresses of the basic log data areas 11a2 to 11n2 of each block lla to lln, the addresses of the general log data areas 11a3 to 11n3, and the used/unused blocks. It includes a management area lOc in which the data is stored in the form of a pointer.

Next, preprocessing for collecting log data will be explained using FIG. 4.

The user uses the keyboard input device 1 to instruct the log data collection mode as necessary (step 100).

Then, if there is any general purpose log data that the user wishes to collect in addition to the basic log data, the user can use the keyboard input device.
The type of general-purpose log data is input using , and the log data collection processing unit 2 takes in the general-purpose log data type (including cases where no specification is made) (step 101). Here, the general-purpose log data includes data related to registers, counters, etc. provided in the computer main body 3, so an identification number is attached to each register, counter, etc., and the user can select the desired one by referring to the manual. Specify the general-purpose log data by inputting the identification number of the register, counter, etc. from which the general-purpose log data is to be retrieved.

The log data collection processing unit 2 then divides the area of the log data storage unit 5 in consideration of the capacity (size) used for one collection of basic log data, and assigns addresses to each of the basic log data areas 11a2 to 11n2. is set in the management table unit 10 (step 102).

Next, the log data collection processing unit 2 determines whether or not the type of general-purpose log data has been specified. If the type of general-purpose log data has not been specified, the process immediately proceeds to step 103, and if the type has been specified, the management table A flag is set in the general-purpose flag area LOa of the unit 10, and the type of the specified general-purpose log data is stored in the general-purpose log data type area 10b (
Steps 104.105).

After that, the size required to store a group of general-purpose log data collected in one collection operation is calculated based on the number and type of general-purpose log data specified, and
1a3 to 11n3 are determined and their addresses are stored in the management area 10c (steps 106, 107). This storage is the basic log data area related to the same number of collection operations! , -La2 to 11n2 and general-purpose log data area 1
1a3 to 11n3 are associated with each other.

After setting the area for such basic log data or basic log data and general-purpose log data, the log data collection processing section 2 notifies the computer main body 3 that the log data collection mode has been instructed. , the series of preprocessing is completed (step 103).

After recognizing that the log data collection mode has been instructed, the computer main body 3 issues a log data write request to the log data collection processing section 2 periodically or when a predetermined collection condition is met.

When the log data collection processing unit 2 notifies the computer main body 3 that the log data collection mode has been instructed,
Thereafter, the collection process shown in FIG. 5 is performed.

In FIG. 5, the log data collection processing unit 2 determines whether or not a write request has been given from the computer main body 3, and if it has not been given, immediately ends the process,
If the basic log data is given, the basic log data is taken out from the computer main body 3 and given to the log data storage section 5 for storage (steps 110 and 111). At this time, based on the contents of the management table unit 10, the data is stored in the basic log data area 1112 of the unused block 1li (i is a to n) pointed to by the pointer.

Next, the general-purpose flag area 10a of the management table section 10
It is determined whether the flag is set or not, and if the flag is not set, the current collection process is ended (step 112). On the other hand, if the flag is set, the type of general-purpose log data stored in the general-purpose log data type area 10b is retrieved, the general-purpose log data is taken out from the computer main body 3, and is given to the log data storage unit 5 for storage ( Steps 113.114). At this time, based on the contents of the management table unit 10, the general-purpose log data area 1 of the unused block (the block to which the above-mentioned basic log data area belongs) pointed to by the pointer is determined.
113.

Note that when the storage in the general-purpose log data area 1113 is completed, the block pointer is incremented for the next collection.

When writing of the general-purpose log data is completed in this way, the current collection process is ended.

Such collection processing is repeated until the log data collection mode is canceled by the user via the keyboard input device 1.

Therefore, according to the above-described embodiment, log data is collected separately into basic log data unrelated to the user's wishes and general-purpose log data that can be selected by the user. The versatility of the system to which this collection method is applied can be increased. As a result, various types of processing using the collected log data, such as failure analysis of a minicomputer system, can be appropriately executed.

Further, the general-purpose log data to be collected can be easily changed without changing the configuration of the log data collection processing section 2, and a system to which the log data collection method is applied can be made easy to use.

In the embodiments described above, the present invention was applied to a minicomputer system, but it can also be applied to other computer systems.

Furthermore, the use of the collected log data is not limited to failure analysis.

[Effects of the Invention] As described above, according to the present invention, part of log data is prepared as general-purpose log data that can be arbitrarily selected, and in addition to basic log data, general-purpose log data specified by the user is Since data can also be collected, the collected log data can be easily changed, and the versatility and usability of the system to which the log data collection method is applied can be improved.
