Abstract

The present invention suppresses the occurrence of such a situation when there is a possibility that a process other than the storage process may interfere with the process of storing a history.
An information processing apparatus (1) buffers log data regarded as having continuity in a primary storage area (111), and logs data stored in the primary storage area (111) when the buffering period expires. Is stored in the secondary storage area 112. In this way, the information processing apparatus 1 has a write speed when the processing other than the storage processing is likely to be delayed by the storage processing of the log data, that is, during the buffering period in which the log data is predicted to be continuous. By writing data to the primary storage area 111 at a high speed, writing of data to the secondary storage area that requires a considerable amount of processing time is avoided. In this way, it is difficult to cause a problem that convenience is impaired due to processing delay or deterioration of responsiveness to user operations.

Description

  The present invention relates to a technique for storing a processing history in an information processing apparatus.

  Various systems for storing processing histories in various information processing apparatuses such as mobile phones and personal computers have been proposed. In these systems, processing performed in the information processing apparatus is monitored, and the contents of the processing are stored as a history. However, there are often other cases where information processing apparatuses use other information processing devices due to the huge amount of these histories or the increase in processing load for acquiring and storing such histories. A problem has been pointed out that the convenience of the information processing apparatus is impaired, for example, the processing is delayed and the responsiveness to the user's operation is deteriorated. As a technique for storing a history, for example, Patent Document 1 proposes a mechanism for determining whether or not to store a history based on the attributes of each device component constituting the information processing apparatus. In Patent Document 2, two types of storage areas, a primary storage area and a secondary storage area, are prepared as history storage destinations, and only those relating to abnormality are stored in the history stored in the primary storage area. A mechanism for transferring to the next storage area has been proposed. Patent Document 3 prepares two types of storage destinations, a primary storage area and a secondary storage area, and first stores a certain amount of history in the primary storage area, and then stores the history in the primary storage area. A mechanism has been proposed in which the history is transferred to the secondary storage area.

Hereinafter, the form for implementing this invention is divided and demonstrated to 1st Embodiment and 2nd Embodiment.
(1) First Embodiment FIG. 1 is a block diagram illustrating a hardware configuration of an information processing apparatus 1 according to a first embodiment. The information processing apparatus 1 is an information processing apparatus that performs information processing such as a mobile phone, a wireless LAN (Local Area Network) terminal, a PDA (Personal Digital Assistants), or a personal computer. Is illustrated. The information processing apparatus 1 includes a control unit 10, a storage unit 11, a display unit 12, an operation unit 13, a wireless communication unit 14, an audio processing unit 15, and an interface 16. These units are connected to each other via a bus 17.

  The control unit 10 includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and a timer. The CPU reads out a control program stored in the ROM, loads it into the RAM, and executes it, thereby controlling each unit of the information processing apparatus 1 and realizing various functions such as a call function, a communication function, and a display function. The RAM serves as a work area when the CPU performs processing, and functions as a primary storage area 111 that temporarily stores data representing a processing history in the information processing apparatus 1 (hereinafter referred to as log data). This RAM is a first storage unit in the information processing apparatus 1. The storage unit 11 is a nonvolatile storage unit such as an EEPROM (Electrically Erasable and Programmable Read Only Memory) or a hard disk, and functions as a secondary storage area 112 that permanently stores log data. The storage unit 11 is a second storage unit in the information processing apparatus 1. Comparing the primary storage area 111 and the secondary storage area 112, the primary storage area 111 is a volatile storage means that is realized by a storage means that has a high data reading and writing speed but a small storage capacity. On the other hand, the secondary storage area 112 is a non-volatile storage unit that is realized by a storage unit that has a low data reading and writing speed but a large storage capacity.

  The display unit 12 includes a liquid crystal display and a video random access memory (VRAM), and displays various images under the control of the control unit 10. The operation unit 13 has a plurality of keys. When the user operates these keys, the operation unit 13 supplies a signal corresponding to the operation content to the control unit 10. The control unit 10 performs processing by determining the operation content based on this signal. The user can instruct the information processing apparatus 1 to perform various processes such as a call instruction, character input, menu selection, and various settings by operating the keys of the operation unit 13. It has become. The wireless communication unit 14 performs wireless communication with a base station of a mobile communication network (not shown) under the control of the control unit 10. By this wireless communication, for example, a call between users of the information processing apparatus 1, transmission / reception of electronic mail, or transmission / reception of various information to / from a server apparatus on the network is performed. The sound processing unit 15 includes sound collection means such as a microphone, sound emission means such as a speaker, and sound processing circuits such as a DSP (Digital Signal Processor). When a call is made, the sound processing unit 15 outputs a sound signal corresponding to the sound collected by the microphone from the speaker through sound processing by the sound processing circuit. The interface 16 is a connection terminal connected to an external device other than the information processing device by a wire, and exchanges various information with the external device.

FIG. 2 is a block diagram illustrating a functional configuration of the information processing apparatus 1.
As shown in the figure, the functions of the information processing apparatus 1 are as follows: a process execution unit 21, a process content acquisition unit 22, a primary storage control unit 23, a continuity determination unit 24, a secondary storage control unit 25, a primary storage region 111, and a secondary storage region 111. A next storage area 112 is included. Among these functions, the processing execution unit 21, the processing content acquisition unit 22, the primary storage control unit 23, the continuity determination unit 24, and the secondary storage control unit 25 are mainly configured so that the CPU of the control unit 10 uses the RAM as a work area. This is realized by executing a control program stored in the ROM. However, the process execution part 21 is implement | achieved not only by the control part 10, but by an audio | voice processing part, a radio | wireless communication part, etc. The primary storage area 111 and the secondary storage area 112 are realized by the RAM of the control unit 10 and the storage unit 11 described above.

  The process execution unit 21 executes all processes in the information processing apparatus 1 such as a program execution process directly performed by the control unit 10 and a voice call process performed under the control of the control unit 10. The processing content acquisition unit 22 constantly monitors the processing content of the processing execution unit 21, acquires the processing content from the processing execution unit 21 when processing that should save log data is performed, and acquires the acquired processing. Generate log data according to the contents. The type of process to store the log data is stored in advance by the process content acquisition unit 22, and the process content acquisition unit 22 stores the type of process stored in itself and the type of process of the process execution unit 21. If they match, it is determined that processing for storing log data has been performed.

  The continuity determination unit 24 is a continuity determination unit that determines whether the acquired log data has temporal continuity when the log data generated by the processing content acquisition unit 22 is acquired. Continuity here refers to the possibility that the continuity of the process of storing log data delays other processes by the process execution unit 21 to deteriorate the responsiveness to the user's operation and impair convenience. To some extent, it means a state where log data storage processing is concentrated within a certain period. The continuity determination unit 24 determines temporal continuity between the log data (more specifically, between the log data newly acquired by the continuity determination unit 24 and the log data that has already been saved). Therefore, a predetermined condition is stored, and whether or not there is continuity is determined based on whether or not the acquired log data satisfies this condition. More specifically, the continuity determination unit 24 stores the log data written in the secondary storage area 112 together with the latest storage date and time (hereinafter referred to as the first old log data) and the previous storage. If the difference between the save date and time and the log data written along with the date and time (hereinafter referred to as the second old log data) is within the threshold, the log data acquired after the first old log data (hereinafter referred to as the new log data) It is determined that there is continuity following the first old log data and the second old log data. The storage date and time here represents the writing time when the log data is written in the secondary storage area 112.

  When the continuity determination unit 24 determines that there is continuity between the new log data and the first old log data and the second old log data, the continuity determination unit 24 notifies the primary storage control unit 23 of the determination. The primary storage control unit 23 stores log data in the primary storage area (hereinafter referred to as buffering) in accordance with the notification from the continuity determination unit 24. When the buffering is started, the primary storage control unit 23 determines that the buffering is finished when a buffering period predetermined by the time measurement by the timer elapses. When the buffering is completed, the primary storage control unit 23 notifies the secondary storage control unit 25 that the buffering is completed (hereinafter, this notification is referred to as a buffering end notification). As described above, since the primary storage area 111 has a high data reading and writing speed, the log data is buffered at a higher speed than the secondary storage area 112.

  Upon receiving the buffering end notification from the primary storage control unit 23, the secondary storage control unit 25 reads all the log data stored in the primary storage area 111, and saves the entire log data as the storage date and time. The time stamp is added and stored in the secondary storage area 112. As described above, since the secondary storage area 112 is a nonvolatile storage unit, log data is stored permanently. In addition, the log data read from the primary storage area 111 is deleted, and a new storage area is secured on the primary storage area 111. These primary storage control unit 23 and secondary storage control unit 25 function as control means for writing log data. As shown in FIG. 2, since the secondary storage area 112 is a component different from the control unit 10, the processing for the secondary storage area 112 is performed using an inter-component communication mechanism such as RPC (Remote Procedure Call). Is to be called.

Subsequently, the operation of the information processing apparatus 1 will be described. In the following description, each function shown in FIG. 2 is expressed as an operation subject, but the actual hardware is the control unit 10 in FIG.
3A and 3B are sequence diagrams illustrating the operation of the information processing apparatus 1.
In FIG. 3A, the processing content acquisition unit 22 constantly monitors the processing content of the processing execution unit 21 and acquires the processing content from the processing execution unit 21 when processing for storing log data is performed ( Step S1). Next, the processing content acquisition unit 22 generates log data from the processing content acquired from the processing execution unit 21 and transfers it to the continuity determination unit 24 (step S2). When the log data is received, the continuity determination unit 24 saves the date and time (TS0) added to the latest first old log data stored in the secondary storage area 112, and more temporally than that. Compare the time stamps as the storage date and time (TS #) added to the previous second old log data, and check whether the difference between the two is within the threshold value. The continuity between the data and the old log data stored in the past is determined (step S3). Here, if the storage date of the first old log data and the second old log data already stored in the secondary storage area are close to each other, the new log data newly acquired this time is also stored in the past. It adopts the idea that log data is considered to be continuous.

  Here, it is assumed that the difference between the two exceeds the threshold, and the continuity determination unit 24 determines that there is no continuity between the new log data and the old log data. If the continuity determination unit 24 determines that there is no continuity, the continuity determination unit 24 delivers the new log data to the secondary storage control unit 25 (step S4). The secondary storage control unit 25 adds a time stamp indicating the storage date (TS1) to the new log data (step S5), and stores the new log data in the secondary storage area 112 (step S6). .

  Next, it is assumed that a new process for storing log data is executed by the process execution unit 21. The processing content acquisition unit 22 acquires the processing content from the processing execution unit 21 (step S7), generates the log data, and passes it to the continuity determination unit 24 (step S8). In the same manner as described above, the continuity determination unit 24 compares the time stamps as the storage dates and times TS1 and TS0 added to the first and second old log data stored in the secondary storage area 112, The continuity between the new log data and the old log data is determined based on whether or not the difference is within the threshold (step S9). Here, it is assumed that the difference between the two exceeds the threshold, and the continuity determination unit 24 determines that there is no continuity between the new log data and the old log data. If the continuity determination unit 24 determines that there is no continuity, the continuity determination unit 24 transfers the new log data to the secondary storage control unit 25 (step S10). The secondary storage control unit 25 adds a time stamp indicating the storage date (TS2) to the new log data (step S11), and stores the new log data in the secondary storage area 112 (step S12). .

  Turning now to the description of FIG. 3B. Furthermore, it is assumed that the process execution unit 21 has executed a new process for storing log data. The processing content acquisition unit 22 acquires the processing content from the processing execution unit 21 (step S13), generates the log data, and transfers it to the continuity determination unit 24 (step S14). In the same manner as described above, the continuity determination unit 24 compares the time stamps as the storage dates and times TS2 and TS1 added to the first and second old log data stored in the secondary storage area 112, The continuity between the new log data and the old log data is determined based on whether or not the difference is within the threshold (step S15). Here, it is assumed that the difference between the two is within the threshold value, and the continuity determination unit 24 determines that there is continuity between the new log data and the old log data. In this case, the continuity determination unit 24 notifies the primary storage control unit 23 that there is continuity and transfers the new log data to the primary storage control unit 23 (step S16).

  When receiving the above notification and new log data from the continuity determination unit 24, the primary storage control unit 23 starts execution of buffering (step S17), and stores the new log data in the primary storage area 111 (step S18). ). Further, the primary storage control unit 23 notifies the processing content acquisition unit 22 that the buffering has started (step S19), and starts counting the buffering period by the timer (step S20). This buffering period is determined in advance and is stored in the primary storage control unit 23. When the processing content acquisition unit 22 receives the notification, the processing content acquisition unit 22 next changes the delivery destination of the new log data delivered from the processing execution unit 21 from the continuity determination unit 24 to the primary storage control unit 23.

  Thereafter, each time processing for storing log data is performed by the processing execution unit 21, the processing content is acquired by the processing content acquisition unit 22 (step S21), and the log data is transferred to the primary storage control unit 23. (Step S22). The primary storage control unit 23 stores the received log data in the primary storage area 111 (step S23). The log data is sequentially stored in the primary storage area 111 along this series of flows until the buffering period elapses.

  When the buffering period due to the timer timing expires, the primary storage control unit 23 ends the execution of buffering (step S24), and notifies the secondary storage control unit 25 of a log data storage instruction for storing the log data. (Step S25). When receiving the log data storage command, the secondary storage control unit 25 reads all the log data buffered in the primary storage area 111 (step S26), and sets a time stamp as the storage date and time for the entire log data. It is added (step S27) and stored in the secondary storage area 112 (step S28). Then, the primary storage control unit 23 notifies the processing content acquisition unit 22 that the buffering is completed (step S29). Upon receiving this notification, the processing content acquisition unit 22 changes the transfer destination of the log data transferred from the processing execution unit 21 from the primary storage control unit 23 to the continuity determination unit 24.

  In addition, after the log data storage process in step S28, when a new process for storing log data is further executed by the process execution unit 21, the secondary storage area is stored in step S28 in the same manner as described above. The time stamp as the storage date and time added to the first old log data stored in 112 and the time as the storage date and time added to the second old log data stored in the secondary storage area 112 in step S12 The stamp is compared, and continuity is determined based on whether or not the difference between the two falls within the threshold.

  As described above, the information processing apparatus 1 according to the first embodiment buffers the log data regarded as having continuity in the primary storage area 111, and when the buffering period expires, the primary storage area The log data stored in 111 is stored in the secondary storage area 112. As described above, the information processing apparatus 1 has a continuity in log data when there is a problem that convenience other than the storage process is delayed due to the storage process of the log data, that is, convenience is lost. During the period when log data must be stored, data is written to the primary storage area 111 having a high writing speed, thereby avoiding writing data to the secondary storage area that requires a considerable amount of processing time. To do. In this way, it is difficult to cause a problem that convenience is lost due to processing delay. Of course, after the buffering period has elapsed, it takes a certain amount of processing time to write data to the secondary storage area, but this writing process is already buffered. This is processing for the entire log data. Therefore, for example, as compared with the case where each piece of log data generated at any time is written to the secondary storage area 112 at different timings, ancillary processing at the time of storing log data, such as adding a time stamp, can be omitted. Thus, the processing load on the information processing apparatus 1 can be reduced.

(2) Second Embodiment Next, a second embodiment will be described. The information processing apparatus 1 according to the second embodiment has the same configuration as the information processing apparatus 1 of the first embodiment, and only the operation thereof is different. More specifically, in the first embodiment, the information processing apparatus 1 stores non-continuous log data in the secondary storage area 112, whereas in the second embodiment, the information processing apparatus 1 First, log data having no continuity is first stored in the primary storage area 111, and additionally stored in the secondary storage area 112. When the information processing apparatus 1 determines whether or not the acquired log data has continuity, the log data written together with the latest storage date and time in the primary storage area 111 instead of the secondary storage area 112 When the difference between the storage date and time (hereinafter referred to as the first old log data) and the log data written with the previous storage date (hereinafter referred to as the second old log data) is within a threshold. Determines that the log data acquired after the first log data (hereinafter referred to as new log data) has continuity following the first old log data and the second old log data.

The operation will be described below with reference to the sequence diagrams of FIGS. 4A and 4B.
In FIG. 4A, the process content acquisition unit 22 monitors the process execution unit 21, and acquires a process content from the process execution unit 21 when a process to save log data is performed (step S30). The processing content acquisition unit 22 generates log data from the processing content acquired from the processing execution unit 21 and transfers it to the continuity determination unit 24 (step S31). When the log data is received, the continuity determination unit 24 saves the date and time added to the latest first old log data stored in the primary storage area 111 and the second previous one in time. Compare the time stamps as the storage date and time added to the old log data, and check whether the difference between the two is within the threshold or not. Is determined (step S32). That is, the difference from the first embodiment is that the continuity determination unit 24 determines the continuity based on the time stamp added to the old data stored in the primary storage area 111 instead of the secondary storage area 112. I am doing it.

If it is determined that there is no continuity, the continuity determination unit 24 transfers the acquired log data to the secondary storage control unit 25 (step S33). The secondary storage control unit 25 adds a time stamp indicating the storage date and time to the log data (step S34), and stores the log data in the primary storage area 111 (step S35). Further, the secondary storage control unit 25 stores this log data in the secondary storage area 112 (step S36). In the subsequent processing, the continuity determination unit 24 determines continuity based on the time stamp added to the old log data stored in the primary storage area 111 in the same manner as steps S32, S35, and S36. If it is determined that there is no continuity, the secondary storage control unit 25 stores the log data in both the primary storage area 111 and the secondary storage area 112.
Since the subsequent processing (including the contents of FIG. 4B) is the same as that of the first embodiment, detailed description thereof is omitted. According to the information processing apparatus according to the second embodiment, it is possible to achieve the same effect as that of the first embodiment.

(3) Modifications The first and second embodiments described above can be modified as follows. These modifications can be combined as appropriate.
(3-1) Modification 1
The condition when the continuity determination unit 24 determines the continuity of the log data is not limited to the contents of the first and second embodiments. For example, the continuity determination unit 24 acquires the acquisition date and time of the log data (new log data) newly acquired by the processing content acquisition unit 22 and the latest stored in the secondary storage area 112 (or the primary storage area 111). The log data (old log data) may be compared with the storage date and time, and whether or not the new log data is continuous may be determined based on whether or not the difference falls within a threshold.
5A and 5B are sequence diagrams illustrating the operation of the information processing apparatus 1 according to the first modification.
In FIG. 5A, the processing content acquisition unit 22 constantly monitors the processing content of the processing execution unit 21 and acquires the processing content from the processing execution unit 21 when processing for storing log data is performed ( Step S40). Next, the processing content acquisition unit 22 generates log data from the acquired processing content and passes it to the continuity determination unit 24 (step S41). When the log data is received, the continuity determining unit 24 receives the log data (new log data) as the date and time when the log data (new log data) is received, and the save date and time added to the latest old log data stored in the secondary storage area 112. The time stamps are compared, and continuity between the new log data and the old log data is determined based on whether or not the difference between the two falls within the threshold (step S42). Here, it is assumed that the difference between the two exceeds the threshold, and the continuity determination unit 24 determines that there is no continuity between the new log data and the old log data. If the continuity determination unit 24 determines that there is no continuity, the continuity determination unit 24 transfers the new log data to the secondary storage control unit 25 (step S43). The secondary storage control unit 25 adds a time stamp indicated as the storage date (TS10) to the new log data (step S44), and stores the new log data in the secondary storage area 112 (step S45). .

Next, it is assumed that the process execution unit 21 executes a new process for storing log data. The processing content acquisition unit 22 acquires the processing content from the processing execution unit 21 (step S46), and transfers the log data to the continuity determination unit 24 (step S47). As described above, the continuity determination unit 24 receives the log data (new log data) (TS20) and the storage date and time added to the old log data stored in the secondary storage area 112. The time stamps as TS10 are compared, and the continuity between the new log data and the old log data is determined based on whether or not the difference between the two falls within the threshold (step S48). Here, it is assumed that the difference between the two is within the threshold value, and the continuity determination unit 24 determines that there is continuity between the new log data and the old log data. In this case, if the continuity determining unit 24 determines that both log data stored at these dates and times are continuous by comparing TS10 and TS20, the continuity determining unit 24 indicates that there is continuity. The primary storage control unit 23 is notified and the log data is transferred to the primary storage control unit 23 (step S49).
Since other operations in the subsequent processing are the same as those in the first embodiment, detailed description thereof is omitted. In addition, the above concept can also be applied to the second embodiment.
Note that the time stamp added to the new log data may be anything corresponding to the date and time when the new log data was acquired. For example, it may be the date and time when the secondary storage control unit 25 stores new log data in the secondary storage area 112 as described above, or the date and time when the continuity determination unit 24 receives new log data. Alternatively, the date and time between the two may be used. Also, any date other than these exemplified dates may be used as long as the date can be regarded as the date when the new log data is acquired.

  In the first and second embodiments, two time stamps added to the old log data are required. However, in the first modification, the continuity determination unit 24 uses the time stamp added to the old log data. You only need to know one. Therefore, compared to the first and second embodiments, the number of times that the continuity determination unit 24 accesses the secondary storage area 112 or the primary storage area 111 can be reduced, and as a result, the processing load of the control unit 10 can be reduced.

(3-2) Modification 2
The criterion for determining the end of the buffering period is not limited to the contents of the first and second embodiments. For example, a predetermined amount of log data may be used as a reference in addition to a time reference based on a timer or not based on a time reference based on a timer. Here, the amount of log data includes one or both of the amount of log data and the number of log data.

6A and 6B are sequence diagrams illustrating the operation of the information processing apparatus 1 according to the second modification.
Since the operation from step S1 to step S19 in FIGS. 6A and 6B is the same as the operation in the first embodiment, detailed description thereof is omitted. Hereinafter, the operation after the primary storage control unit 23 in FIG. 6B starts buffering and notifies the processing content acquisition unit 22 (after step S19) will be described.
In FIG. 6B, the primary storage control unit 23 starts timing by a timer and starts monitoring the amount of log data received from the processing content acquisition unit 22 (step S50). As described above, the amount of log data includes one or both of the amount of log data and the number of log data. Next, the process content acquisition unit 22 monitors the process execution unit 21, and acquires the process content from the process execution unit 21 when a process for storing log data is performed (step S51). When receiving the buffering start notification from the primary storage control unit 23, the processing content acquisition unit 22 delivers the log data to the primary storage control unit 23 (step S52). The primary storage control unit 23 stores the log data in the primary storage area 111 (step S53). The log data is stored in the primary storage area 111 along this series of flows until the buffering is completed by the primary storage control unit 23. When the timer in the primary storage control unit 23 expires or the amount of log data stored in the primary storage area 111 reaches a threshold value, the primary storage control unit 23 finishes the buffering (step S54). Since the subsequent processing is the same as the operation in the first embodiment, detailed description thereof is omitted. The above concept can also be applied to the second embodiment. In the above example, the amount of log data is used as a reference in addition to the time reference by the timer, but the amount of log data may be used as a reference instead of the time reference by the timer.

  In the second modification, since the end of buffering is determined based on the log data amount, it is possible to limit the amount of buffering according to the storage procedure of the primary storage area 111. Therefore, for example, even if there is a hardware constraint such as a low storage capacity volatile memory must be used for the primary storage area 111 due to problems with manufacturing cost and physical space of the information processing apparatus 1, This can be dealt with.
