Description

Log data saving device and log data saving method

The present invention relates to a technique for saving log data during program execution, and more particularly to a technique for saving log data of a display control program for displaying an image on a display device.

In the development of equipment such as an in-vehicle device that realizes its operation by executing the program, log data generated by each program (hereinafter sometimes simply referred to as “log”) was acquired and generated in the equipment. Analyzing the content of a failure is performed (for example, Patent Document 1 below).

Generally, since log data of a program is stored in a storage device that is cyclically overwritten, old log data is lost when the log data increases. Therefore, log data generated by a program when a failure occurs is preferably saved and backed up in another storage device that is not likely to be lost in order to perform failure analysis later. This transfer of log data to another storage device that is not likely to be lost is called “evacuation”.

JP 2014-182715 A

For example, if log data at the time of failure occurrence can be automatically extracted by a technique such as log pattern matching, log data necessary for failure analysis can be automatically saved. However, in the development of information processing devices that display images on the screen of display devices, there are obstacles that can only be confirmed visually, such as flickering of the screen and misalignment of the component images that make up the screen. It is difficult to detect.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a log evacuation apparatus that can evacuate log data when a failure that can only be visually confirmed occurs. .

A log data saving device according to the present invention is a log data saving device for a display control program that displays an image on a display device, and includes an operation detection unit that detects a user's specific operation on an input device, and a display control program. A log saving unit that extracts and saves a part of the output log data. The log saving unit starts saving the log data output by the display control program when the operation detection unit detects a specific operation. .

According to the log evacuation device according to the present invention, it is possible to evacuate log data when a failure occurs that can only be confirmed visually on the screen of the display device.

The objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description and the accompanying drawings.

<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of an information display system according to the present invention. The information display system includes a display control device 100, and a display device 101 and an input device 102 connected thereto. Examples of such an information display system include a car multimedia terminal mounted on a vehicle.

The display device 101 displays an image corresponding to a display signal output from the display control device 100 on a screen, and is, for example, a liquid crystal display device. The input device 102 is a user interface for the user to operate the display control device 100 and the display device 101. The input device 102 may be a hardware key such as a physical button, a keyboard, or a mouse, or may be a software key displayed on the screen. The display device 101 and the input device 102 may be configured as one touch panel by displaying a software key as the input device 102 on the screen of the display device 101.

The display control device 100 includes a display control unit 1, a log output unit 2, a log holding unit 3, and a log saving device 10.

The display control unit 1 and the log output unit 2 are components realized when the processor of the display control apparatus 100 executes a display control program stored in the memory. The display control unit 1 generates a display signal for causing the display device 101 to display an image. The log output unit 2 outputs log data indicating the operation status of the display control unit 1, that is, the execution status of the display control program. Here, the log output unit 2 includes a normal log output unit 2a that outputs a normal log, a detailed log output unit 2b that outputs a detailed log, and a serial log output unit 2c that outputs a serial log. It is sufficient that at least one of them is provided. Hereinafter, the normal log, detailed log, and serial log output by the log output unit 2 are collectively referred to as “log data”.

The log holding unit 3 is a storage device that holds log data output by the log output unit 2. Here, it is assumed that the log holding unit 3 cyclically overwrites and saves log data. That is, the log data in the log holding unit 3 is overwritten by new log data and disappears while the display control unit 1 continues to operate.

The log saving device 10 extracts a part of the log data written in the log holding unit 3 during the operation test of the display control device 100 and saves it in a storage device different from the log holding unit 3. Log data is backed up. The log save device 10 includes an operation detection unit 11, a log save unit 12, and a save log holding unit 13.

The operation detection unit 11 detects a user's specific operation on the input device 102. The log saving unit 12 extracts the latest log data written in the log holding unit 3 (that is, the log data output immediately before by the log output unit 2) when the operation detection unit 11 detects a specific operation. And saved in the save log holding unit 13. As illustrated in FIG. 1, the log saving unit 12 includes a log extraction control unit 12a that specifies an extraction range of log data according to a detection result of a specific operation by the operation detection unit 11, and a range specified by the log extraction control unit 12a. The log data is extracted from the log holding unit 3 and is saved in the save log holding unit 13.

The log data that the log saving unit 12 saves in the save log holding unit 13 includes the normal log output by the normal log output unit 2a, the detailed log output by the detailed log output unit 2b, and the serial log output by the serial log output unit 2c. Either may be sufficient and two or more of them may be sufficient. Further, the user may arbitrarily set which of the normal log, the detailed log, and the serial log is saved in the save log holding unit 13.

The save log holding unit 13 is a storage device that holds log data saved by the log save unit 12. The evacuation log holding unit 13 preferably keeps holding the log data unless the user orders deletion. Therefore, it is preferable that the storage capacity of the save log holding unit 13 is larger than that of the log holding unit 3.

If the save log holding unit 13 has a sufficiently large storage capacity, the save log holding unit 13 may cyclically save the log data in the same manner as the log holding unit 3. Since the log data saved by the log saving unit 12 is only a part of the log data written to the log holding unit 3, the time for which the log data is held in the save log holding unit 13 is longer than that of the log holding unit 3. Will be long enough. Further, if the capacity of the save log holding unit 13 is large, the time can be made longer.

FIG. 2 is a diagram illustrating a hardware configuration of the log saving device 10. As shown in FIG. 2, the log saving device 10 includes at least a processor 51, a memory 52, and an input / output interface (I / F) 53.

The processor 51 is a CPU (also referred to as a central processing unit, a central processing unit, a processing unit, a processing unit, a microprocessor, a microcomputer, a processor, or a DSP) that executes a program stored in the memory 52. The memory 52 includes, for example, RAM (Random-Access Memory), ROM (Read-Only Memory), flash memory, EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically-Erasable Programmable Read-Only Memory), Nonvolatile or volatile semiconductor memories, magnetic disks, flexible disks, optical disks, compact disks, mini disks, DVDs (Digital Versatile Discs), and the like are applicable.

When the log saving device 10 is applied to the display control device 100 as in the present embodiment, the processor 51 may be the same as the processor that executes the display control program that implements the display control unit 1 and the log output unit 2. Good. Further, the memory 52 may be the same as a memory that stores the display control program or a storage device as the log holding unit 3.

The display device 101 and the input device 102 are connected to the input / output interface 53. In FIG. 1, the display device 101 and the input device 102 are externally attached to the display control device 100 including the log saving device 10, but they may be integrally configured.

The function of each element (the operation detection unit 11, the log saving unit 12, and the saving log holding unit 13) of the log saving device 10 is realized by the processor 51 executing a program stored in the memory 52. That is, the log evacuation device 10 extracts an operation detection unit 11 that detects a user's specific operation on the input device 102 and log data output by the display control program when the operation detection unit 11 detects a specific operation. The log saving unit 12 to be saved in the save log holding unit 13 is provided with a processor 51 that is realized by executing a program. The save log holding unit 13 is realized using a part of the memory 52.

In other words, the log evacuation device 10 is executed by the processor 51 to confirm whether or not the user's specific operation has been performed on the input device 102 and display control when detecting the specific operation. The process of starting saving the log data output by the program includes a memory 52 for storing the program executed as a result. These programs can also be said to cause a computer to execute these processes and procedures.
