[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. <Embodiment> A processing system 1 according to an embodiment of the present disclosure will be described with reference to the drawings. The processing system 1 is a system that collects log information of a storage device 20.

[0012] (Configuration of the processing system of the present disclosure) 1 is a diagram illustrating an example of a configuration of a processing system 1 according to some embodiments of the present disclosure. As shown in FIG. 1, the processing system 1 according to one embodiment of the present disclosure includes a maintenance terminal 10 and a storage device 20.

[0013] The maintenance terminal 10 is a terminal that connects to the storage device 20 when a problem occurs in the storage device 20, and checks the status of the storage device 20 and collects log information. As shown in FIG. 1 , the maintenance terminal 10 includes a log information request unit 101, a log information storage unit 102, a final event time information storage unit 103, and a log information synthesis unit 104.

[0014] The log information request unit 101 functions as an interface with the storage device 20. The log information request unit 101 requests and receives log information. The interface may use a commonly used web-based technology using HTTP. Alternatively, the interface may use a REST API or a technology that uniquely defines SCSI commands.

[0015] The log information storage unit 102 stores log information i1. FIG. 2 is a diagram illustrating an example of log information i1 stored in the log information storage unit 102 according to some embodiments of the present disclosure. The log information i1 is information in which events and operations that have occurred in the storage device 20 are recorded in chronological order. The log information i1 includes time information such as the year, month, date, hour, minute, and second, and event information that occurred at that time. The example of log information i1 illustrated in FIG. 2 is log information that can register up to m events. In the log information i1 illustrated in FIG. 2, event 1 at time 1 is the oldest event. Also, in the log information i1 illustrated in FIG. 2, event m at time m is the newest event.

[0016] The log information storage unit 102 also stores a difference log i2. FIG. 3 is a diagram illustrating an example of the difference log i2 stored in the log information storage unit 102 according to some embodiments of the present disclosure. The difference log i2 is information in which new events and operations that occurred in the storage device 20 are recorded in chronological order after the storage device 20 collected the log information i1 from the maintenance terminal 10. Like the log information i1, the difference log i2 includes time information such as the year, month, date, and hour, minute, and second, as well as event information that occurred at that time. In the example of the difference log i2 illustrated in FIG. 3, the log information i1 is collected from the maintenance terminal 10 once when the event m at time m is registered. Then, the event m+1 occurs at time m+1. Therefore, the difference log i2 contains only one event registered. The difference log i2 also has an identifier so that it can be determined whether the information type is the log information i1 or the difference log i2.

[0017] The final event time information storage unit 103 stores the final event time information i3. The final event time information i3 includes the time of the most recent event among the log information i1 that the maintenance terminal 10 has already acquired. For example, in the example of log information i1 shown in FIG. 2, time m corresponds to the final event time information i3. Furthermore, if the storage device 20 never acquires log information i1 from the maintenance terminal 10, time information indicating invalidity is set as the initial value for the final event time information i3 stored in the final event time information storage unit 103.

[0018] The log information combining unit 104 executes a process of combining the difference log i2 with the log information i1. The log information storage unit 102 has a finite storage space. Therefore, the process of combining the difference log i2 with the log information i1 is performed by the log information combining unit 104 as follows. That is, similar to storing data cyclically in a ring buffer, the log information combining unit 104 first deletes the oldest events from the log information i1 by the number of events registered in the difference log i2. Then, the log information combining unit 104 adds the events from the difference log i2 to the newest events in the log information i1.

[0019] The log information combining unit 104 stores the log information i4. FIG. 4 is a diagram illustrating an example of the log information i4 stored by the log information combining unit 104 according to some embodiments of the present disclosure. The log information i4 illustrates a state after the difference log i2 illustrated in FIG. 3 is combined with the log information i1 illustrated in FIG. 2. The difference log i2 has one event. Therefore, the log information combining unit 104 deletes the oldest event in the log information i1, event 1 at time 1. Then, the log information combining unit 104 adds the event m+1 at time m+1 after the newest event in the log information i1, event m at time m. In this way, the log information i4 illustrated in FIG. 4 is generated.

[0020] For example, the maintenance terminal 10 is a device such as a general-purpose notebook computer with dedicated software installed and equipped with an Ethernet LAN port.

[0021] The storage device 20 is a device that stores data in the processing system 1. The storage device 20 includes a log information collection unit 201, a difference log extraction unit 202, and a log information storage unit 203, as shown in FIG.

[0022] The log information collection unit 201 functions as an interface with the maintenance terminal 10. The log information collection unit 201 receives log information requests from the maintenance terminal 10 and transmits log information generated in the storage device 20 to the maintenance terminal 10. If the interface uses a commonly used web-based technology using HTTP, the log information collection unit 201 will have the functionality of a web server. Note that the log information collection unit 201 may use any interface technology as long as it has a server function that can transmit data in response to a request from a client, which is a user.

[0023] The difference log extraction unit 202 extracts events that have not yet been acquired by the maintenance terminal 10 from the events accumulated in the log information i2, based on the last event time information i3 passed as an argument of the log information request from the maintenance terminal 10. Specifically, for example, the difference log extraction unit 202 compares the time indicated by the last event time information i3 passed as an argument with the time indicated by the log information i2, and extracts information on events that have not yet been extracted from the events accumulated in the log information i2.

[0024] The log information storage unit 203 stores the log information i5 and the difference log i6. When the difference log extraction unit 202 extracts the difference log i6 from the log information i5, the log information storage unit 203 stores the difference log i6. FIG. 5 is a diagram illustrating an example of the log information i5 stored in the log information storage unit 203 according to some embodiments of the present disclosure. FIG. 6 is a diagram illustrating an example of the difference log i6 stored in the log information storage unit 203 according to some embodiments of the present disclosure. In the log information i5 illustrated in FIG. 5, event 2 at time 2 is the oldest event. In the log information i5 illustrated in FIG. 5, event m+1 at time m+1 is the newest event. The content of the log information i5 illustrated in FIG. 5 is the same as the content of the log information i4 illustrated in FIG. 4. The content of the difference log i6 illustrated in FIG. 6 is the same as the content of the difference log i2 illustrated in FIG. 3.

[0025] The above-described processing performed by the processing system 1 according to the embodiment of the present disclosure is merely an example, and the processing system 1 is not limited to the above-described processing. For example, the processing system 1 may perform the processing described below.

[0026] (First process performed by the processing system of the present disclosure) 7 is a diagram illustrating a first example of a processing flow of the processing system 1 according to some embodiments of the present disclosure. Here, a process up to collecting log information of the storage device 20 performed by the processing system 1 as illustrated in FIG. 7 will be described.

[0027] At any timing, a maintenance technician executes an operation to collect log information from the maintenance terminal 10. In response to the operation, the log information request unit 101 issues a log information request with the final event time information i3 attached to the storage device 20 (step S1). Note that in the first log information request, a value indicating invalidity is set to the final event time information i3.

[0028] The log information collecting unit 201 of the storage device 20 checks the last event time information i3 attached to the received log information request (step S2). Then, based on the check result, the log information collecting unit 201 determines whether the last event time information i3 is valid time information (i.e., whether it is valid time information or invalid time information) (step S3). For example, if the log information collecting unit 201 determines that the time of the last event time information i3 is included in the range from the time of the oldest event to the time of the newest event in the log information, the log information collecting unit 201 determines that the last event time information i3 is valid time information. On the other hand, if the log information collecting unit 201 determines that the time of the last event time information i3 is not included in the range from the time of the oldest event to the time of the newest event in the log information, the log information collecting unit 201 determines that the last event time information i3 is invalid time information.

[0029] There are two possible cases in which the log information collecting unit 201 determines that the time of the last event time information i3 is not included in the range from the time of the oldest event to the time of the newest event in the log information. The first case is when the first log information request is made. The second case is when the maximum number of events that can be registered in the log information has occurred since the previous log information request.

[0030] Here, the second point will be described in detail. FIG. 8 is a diagram illustrating a determination by the log information collection unit 201 according to some embodiments of the present disclosure. FIG. 8 is a diagram illustrating log information i7. A maximum of m events can be registered in the log information i7. In the example of the log information i7 shown in FIG. 8, event m+1 at time m+1 is the oldest event, and event m+m at time m+m is the newest event. When the log information collection unit 201 receives last event time information i3 including a log information request for time m, the log information collection unit 201 determines that time m is not included in the range from the oldest time m+1 to the newest time m+m of the log information i7. Therefore, the log information collection unit 201 determines that the last event time information i3 is invalid time information.

[0031] If the log information collecting unit 201 determines that the final event time information i3 is invalid time information (NO in step S3), it selects log information stored in the log information storage unit 203 (step S4). Then, the log information collecting unit 201 transfers the selected log information to the maintenance terminal 10 (step S5).

[0032] Furthermore, if the log information collection unit 201 determines that the final event time information i3 is valid time information (YES in step S3), it instructs the difference log extraction unit 202 to extract only events that occurred after the time of the final event time information i3. The difference log extraction unit 202 generates a difference log by extracting the relevant event from the log information stored in the log information storage unit 203 (step S6). An example of the log information at this time is the log information i5 shown in FIG. 5. An example of the difference log at this time is the difference log i6 shown in FIG. 6. The log information collection unit 201 selects a difference log stored in the log information storage unit 203 (step S7). Then, the log information collection unit 201 transfers the selected difference log to the maintenance terminal 10 (step S8).

[0033] The log information request unit 101 of the maintenance terminal 10 receives the data from the storage device 20. Then, the log information request unit 101 determines whether the received data is log information or a difference log (step S9).

[0034] When log information requesting unit 101 determines that the received data is log information ("log information" in step S9), it deletes old log information stored in log information storage unit 102. Then, log information requesting unit 101 stores the current log information in the area of ​​log information storage unit 102 that has become free by deleting the old log information (step S10).

[0035] Furthermore, when the log information request unit 101 determines that the received data is a difference log ("Difference log" in step S9), it stores the difference log in the log information storage unit 102. Then, the log information synthesis unit 104 combines the currently acquired difference log with the log information stored in the log information storage unit 102 (step S11). An example of the log information at this time is the log information i1 shown in FIG. 2. An example of the difference log at this time is the difference log i2 shown in FIG. 3. The combination of these is the log information i4 shown in FIG. 4.

[0036] Finally, the log information request unit 101 sets the time of the oldest event in the log information stored in the log information storage unit 102 as the final event time information i3 (step S12).

[0037] (advantage) The processing system 1 according to an embodiment of the present disclosure has been described above. In the processing system 1 including the maintenance terminal 10 (an example of a terminal device) and the storage device 20, the last event time information storage unit 103 (an example of a first processing unit) stores the time of the last event in the collected log information. The log information request unit 101 (an example of a second processing unit) transmits a log information request with the time attached to the storage device 20.

[0038] This processing system 1 can transmit a log information request, to which the time of the last event in the collected log information is attached, to the storage device 20. This allows the processing system 1 to determine whether the time information is valid or invalid. As a result, it is possible to determine the data to be transmitted to the maintenance terminal 10 of the processing system 1. In other words, the processing system 1 can improve convenience.

[0039] Next, a processing system 1 according to some embodiments of the present disclosure will be described. Fig. 9 is a diagram illustrating an example of the configuration of the processing system 1 according to some embodiments of the present disclosure. As shown in Fig. 9, the processing system 1 includes a terminal device 301 and a storage device 302. The terminal device 301 includes a first processing unit 3011 and a second processing unit 3012.

[0040] The first processing unit 3011 holds the time of the last event in the collected log information. The second processing unit 3012 sends the log information request with the time attached to it to the storage device.

[0041] The first processing unit 3011 can be realized, for example, by using the function of the last event time information storage unit 103 illustrated in Fig. 1. The second processing unit 3012 can be realized, for example, by using the function of the log information request unit 101 illustrated in Fig. 1. The terminal device 301 can be realized, for example, by using the function of the maintenance terminal 10 illustrated in Fig. 1. The storage device 302 can be realized, for example, by using the function of the storage device 20 illustrated in Fig. 1.

[0042] Next, processing performed by the processing system 1 according to some embodiments of the present disclosure will be described. Fig. 10 is a diagram showing an example of a processing flow of the processing system 1 according to some embodiments of the present disclosure. Here, the processing of the processing system 1 will be described with reference to Fig. 10.

[0043] In a processing system 1 including a terminal device 301 and a storage device 302, a first processing unit 3011 holds the time of the last event in the collected log information (step S101). A second processing unit 3012 transmits a log information request with the time attached to the storage device 302 (step S102).

[0044] The processing system 1 according to some embodiments of the present disclosure has been described above. This processing system 1 can improve convenience.

[0045] The order of the processes in each embodiment of the present disclosure may be changed as long as the processes are performed appropriately.

Furthermore, CPU 6 allocates storage areas in main memory 7 corresponding to each of the above-described storage units in accordance with the program.

[0049] Examples of storage 8 include a hard disk drive (HDD), a solid state drive (SSD), a magnetic disk, a magneto-optical disk, a compact disc read-only memory (CD-ROM), a digital versatile disc read-only memory (DVD-ROM), and a semiconductor memory. Storage 8 may be an internal medium directly connected to the bus of computer 5, or an external medium connected to computer 5 via interface 9 or a communication line. In addition, when this program is distributed to computer 5 via a communication line, computer 5 that receives the program may load the program into main memory 7 and execute the above-mentioned processing. In at least one embodiment, storage 8 is a non-transitory tangible storage medium.
