  Next, Example 1 of the present invention will be described. FIG. 11 and FIG. 12 are diagrams showing a procedure for storing procedure reproduction data according to the first embodiment of the present invention. First, in FIG. 11, the parameter setting unit 10 (see FIG. 1) sets parameters according to the user's designation input, and creates a definition file (step S1). Next, the recording processing unit 3 acquires the definition file from the definition file storage unit 11 and analyzes the information set in the definition file (step S2). The recording processing unit 3 refers to the “target application name” in the definition file and determines whether the target application indicated by the target application name has started (step S3). If the recording processing unit 3 determines that the target application is not activated, the process returns to step S3. When the recording processing unit 3 determines that the target application has been activated, the current time acquisition unit 31 of the recording processing unit 3 acquires the current time (step S4).

  The screen capture acquisition unit 32 acquires a screen capture image (step S5). The process information acquisition unit 33 acquires process information (step S6). The application information acquisition unit 34 acquires application information (step S7). The CPU usage rate acquisition means 35 acquires the CPU usage rate (step S8). The memory resource status acquisition unit 36 acquires the memory resource status (step S9). The HDD access information acquisition unit 37 acquires HDD access information (for example, HDD access amount) (step S10). The network usage amount acquisition unit 38 acquires the network usage amount (step S11).

  Next, in step S12 of FIG. 12, the recording processing unit 3 stores the information acquired by the processing of steps S4 to S11 of FIG. 11 in the storage device 9 (step S12). The elapsed time determination means 43 starts measuring the elapsed time after the acquired information is stored in the storage device 9 (step S13). A predetermined monitoring means (not shown) provided in the recording processing unit 3 determines whether the target application is terminated (due to a failure) (step S14). If the target application has not ended, the keyboard event monitoring unit 40 determines whether there is a keyboard input (step S15). If the target application is terminated, the process proceeds to step S18. If the keyboard event monitoring unit 40 determines that there is a keyboard input, the process returns to the process of step S4 in FIG. When the keyboard event monitoring unit 40 determines that there is no keyboard input, the mouse event monitoring unit 41 determines whether there is a mouse input (step S16). If the mouse event monitoring unit 41 determines that there is a mouse input, the process returns to step S4 in FIG. If the mouse event monitoring unit 41 determines that there is no mouse input, has the predetermined time (for example, 100 ms) elapsed since the elapsed time determination unit 43 started measuring the elapsed time in step S13? (Elapsed time> 100 msec) is determined. The predetermined time is, for example, the time set in “definition data 1” of “information acquisition interval” in the definition file shown in FIG.

  When the elapsed time determination unit 43 determines that a predetermined time has not elapsed since the measurement of the elapsed time is started, the process returns to step S15. When the elapsed time determination unit 43 determines that a predetermined time has elapsed since the measurement of the elapsed time was started, the process returns to step S4 in FIG.

  In step S18, the event log information acquisition unit 39 acquires and generates event log information (step S18) and stores it in the storage device 9 (step S19). For example, the event log information acquisition unit 39 stores event log information having a file format as shown in FIG. Then, the procedure reproduction data creating means 42 creates procedure reproduction data (step S20), stores it in the storage device 9, and ends the process.

  13 to 15 are diagrams illustrating an example of a process flow for reproducing an application failure by the procedure reproducing unit. First, in step S31 of FIG. 13, the program activation / termination means 52 refers to the “target application name” in the definition file and activates the target application (step S31). The procedure reproduction data analysis processing means 51 analyzes the first entry of the procedure reproduction data (step S32). The program start / end means 52 determines whether or not the process reproduction data (first entry) includes process information (step S33). If the program start / end means 52 determines that there is no process information in the procedure reproduction data, the process proceeds to step S35. When the program activation / termination means 52 determines that the process reproduction data includes process information, the program activation / termination means 52 determines whether the application information is present in the procedure reproduction data (first entry thereof) (step). S35). Specifically, the program start / end means 52 determines whether there is application information corresponding to an application other than the target application in the entry.

  If the program start / end means 52 determines that there is no application information in the procedure reproduction data (first entry), the process proceeds to step S37. When the program activation / termination unit 52 determines that the application information is included in the procedure reproduction data (first entry), the program activation / termination unit 52 activates the application corresponding to the application information.

  Next, the mouse input setting means 54 determines whether or not mouse event occurrence information is set in the procedure reproduction data (first entry) (step S37). If the mouse input setting unit 54 determines that mouse event occurrence information is not set in the entry, the process proceeds to step S39. If the mouse input setting means 54 determines that mouse event occurrence information is set in the entry, it generates and reproduces (mouse input) a mouse event corresponding to the mouse event occurrence information (step S38).

  Next, the keyboard input setting unit 53 determines whether or not keyboard event occurrence information is set in the procedure reproduction data (first entry) (step S39). If the keyboard input setting unit 53 determines that the keyboard event occurrence information is not set in the entry, the process proceeds to step S41 in FIG. When the keyboard input setting means 53 determines that keyboard event occurrence information is set in the entry, it generates and reproduces (keyboard input) a keyboard event corresponding to the keyboard event occurrence information (step S40).

  Next, in step S41 of FIG. 14, the procedure reproduction data analysis processing means 51 determines whether or not there is a next entry in the procedure reproduction data (step S41). If the procedure reproduction data analysis processing unit 51 determines that there is no next entry in the procedure reproduction data, the process proceeds to step S48 in FIG. When the procedure reproduction data analysis processing unit 51 determines that the next entry exists in the procedure reproduction data, the procedure reproduction data analysis processing unit 51 analyzes the next entry of the procedure reproduction data (step S42). The procedure reproduction data analysis processing means 51 adjusts the execution timing of the process corresponding to the next entry based on the analysis result of the next entry (step S43). The program start / end means 52 refers to the process information corresponding to the entry to determine whether the process has changed (increased or decreased) (step S44). If the program start / end means 52 determines that the process does not change, the process proceeds to step S46. If the program start / end means 52 determines that the process has changed, the program start / end means 52 starts or stops the process (step S45). Next, the program start / end means 52 refers to the application information corresponding to the entry to determine whether the application has changed (increased or decreased) (step S46). If the program start / end means 52 determines that the application does not change, the process returns to step S37. When the program start / end means 52 determines that the application has changed, the program start / end means 52 starts or stops the application (step S47).

  In step S48 of FIG. 15, the event log information acquisition unit 55 acquires and generates event log information (step S48). Next, the event log information acquisition unit 55 determines whether the application failure has been reproduced (step S49). The event log information acquisition unit 55 determines whether the event log information acquired / generated in step S48 includes the aforementioned comparison target entry of the event log information stored in the storage device 9, and the acquisition / generation When the compared event log information includes a comparison target entry, it is determined that the application failure has been reproduced. For example, the event log information acquisition unit 55 includes “type” corresponding to an entry in which “existence” is set in “comparison / non-comparison” of the event log information as shown in FIG. ”,“ Source ”, and“ Event ”The same“ Type ”,“ Source ”, and“ Event ”are determined to be included, and if this entry is included, the application failure Judge that reproduced. When the comparison target entry is not included in the event log information acquired / generated in step S48, the event log information acquisition unit 55 determines that the application failure has not been reproduced, and ends the process.

  Next, the process information acquisition unit 56 acquires process information (step S50), and determines whether the application failure has been reproduced (step S51). The process information acquisition unit 56 determines whether the process information acquired in step S50 indicates the same process state as the process information at the time of application failure occurrence (process information at the time of application failure occurrence in the procedure reproduction data), When the process information acquired in step S50 indicates the same process state as the process information at the time of occurrence of the application failure, it is determined that the application failure has been reproduced, and the process is terminated. If the process information acquired in step S50 does not indicate the same process state as the process information at the time of occurrence of the application failure, the process information acquisition unit 56 determines that the application failure has not been reproduced, and proceeds to step S52.

  In step S52, the reproduction data changing unit 57 determines whether to change the generation timing of the mouse event and the generation timing of the keyboard event executed in steps S38 and S40 of FIG. 13 (step S52). Specifically, the reproduction data changing unit 57 refers to the setting content of “change in event generation timing” in the definition file, and “executes” “definition data 1” of “change in event generation timing”. If it is determined that it is set, it is determined that the generation timing of the mouse event and the generation timing of the keyboard event are changed. When it is determined that “not implemented” is set in “definition data 1” of “change in event generation timing”, it is determined that the generation timing of the mouse event and the generation timing of the keyboard event are not changed.

  If the reproduction data changing unit 57 determines not to change the generation timing of the mouse event and the generation timing of the keyboard event, the process ends. If the reproduction data changing unit 57 determines to change the generation timing of the mouse event and the generation timing of the keyboard event, the reproduction data changing unit 57 determines whether to change the procedure reproduction data (step S53). Specifically, the reproduction data changing unit 57 refers to the definition file and determines whether to change the CPU usage rate, the memory usage amount, the HDD access amount, and the network usage amount of the procedure reproduction data. If the reproduction data changing unit 57 determines not to change the procedure reproduction data, the process is terminated. When the reproduction data changing unit 57 determines to change the procedure reproduction data, the reproduction data changing unit 57 changes the procedure reproduction data (step S54) and returns to step S32 in FIG. In step S54 of FIG. 15, for example, the reproduction data changing means 57 generates the mouse event generation timing and the keyboard event generation for the time set in “definition data 1” of “variation of event occurrence timing” in the definition file. The timing is changed (the “time” corresponding to the entry in which the mouse event occurrence information and keyboard event occurrence information in the procedure reproduction data is set) is changed. Further, for example, the reproduction data changing unit 57 includes “definition data 2” in “change in CPU usage”, “change in memory usage”, “change in HDD access”, and “change in network usage” in the definition file. The CPU usage rate, the memory usage amount, the HDD access amount, and the network usage amount of the procedure reproduction data are changed by a value corresponding to the ratio set to “”. For example, the reproduction data changing unit 57 reduces or increases the system resource usage (rate) such as CPU usage, memory usage, HDD access, and network usage, and then performs each process of the procedure reproduction unit 5. It is possible to determine whether or not the application failure depends on the usage amount (rate) of the system resource by the means repeatedly executing the application failure reproduction process.

  According to one embodiment of the present invention, in steps S53 and S54 in FIG. 15, the reproduction data changing unit 57 deletes a predetermined application set as application information in the procedure reproduction data, and adds a predetermined application. A setting process may be executed.

  In step 61 of FIG. 16, the procedure reproduction data analysis processing means 71 of the reproduction processing unit 7 reads and acquires the procedure reproduction data from the storage device 9, and analyzes the entry of the procedure reproduction data (step S61). In step S61, the screen capture acquisition unit 73 further acquires the screen capture image indicated by the image file name included in the entry from the storage device 9. The current time acquisition unit 72 acquires the current time (step S62). The procedure reproduction data analyzing means 71 adjusts the execution timing of the reproduction process corresponding to the entry based on the time included in the entry analyzed in step S61 and the current time acquired in step S62 (step S63). . Then, the screen display means 74 displays the time included in the entry on the screen (step S64). The screen display means 74 displays the screen capture image acquired in step S61 on the screen (step S65). The screen display means 74 displays the CPU usage rate included in the entry on the screen (step S66). The screen display means 74 displays the memory usage included in the entry on the screen (step S67), and proceeds to step S68 in FIG.

  In step S68 of FIG. 17, the screen display means 74 displays the HDD access amount included in the entry on the screen (step S68). The screen display means 74 displays the network usage included in the entry on the screen (step S69). The screen display unit 74 displays the mouse operation information indicated by the mouse event occurrence information included in the entry (step S70). The screen display unit 74 displays the keyboard operation information indicated by the keyboard event occurrence information included in the entry (step S71). The procedure reproduction data analysis processing means 71 determines whether there is a next entry in the procedure reproduction data (step S72). If the procedure reproduction data analysis processing means 71 determines that there is no next entry in the procedure reproduction data, the process is terminated. If the procedure reproduction data analysis processing means 71 determines that there is a next entry in the procedure reproduction data, the process returns to step S61 in FIG. Note that in steps S64 to S67 in FIG. 16 and steps S68 to S71 in FIG. 17 described above, the screen display unit 74 sequentially displays screen information corresponding to each piece of information to be displayed on the screen included in the entry. As described above, the screen display unit 74 may generate one piece of screen information corresponding to all pieces of information to be displayed on the screen included in the entry, and display the generated screen information at a time.

(A), (B), and (C) of FIG. 18 respectively show a screen display example of information to be displayed on the screen included in the first entry of the procedure reproduction data, and the second entry of the procedure reproduction data. A screen display example of information to be displayed on the screen, and a screen display example of information to be displayed on the screen included in the third entry of the procedure reproduction data (for example, an entry when an application failure occurs) are shown. For example, a key corresponding to the letter A is highlighted on the screen shown in FIG. 18B, and the user who sees the screen knows that the key has been pressed. Further, for example, the date and time, CPU usage rate, memory usage amount, C drive access amount, D drive access amount, and network access amount are displayed on the screen shown in FIG. 18C.

  Further, the user who refers to the screens shown in FIGS. 18A to 18C can know the execution state of the application in a time series from the start of the application until the failure occurs. For example, after a character “A” is displayed on the screen in response to a key depression (see FIG. 18B) from a state in which the character drawing application does not display the character (see FIG. 18A) (see FIG. 18B). , It can be seen that an application failure has occurred while the characters “AB” are displayed on the screen.

  Next, a second embodiment of the present invention will be described. In the second embodiment of the present invention, the system load fluctuation unit 6 executes the fluctuation process of the system load state in cooperation with the application fault reproduction process. The procedure reproduction data recording process and the application failure reproduction process according to the second embodiment of the present invention are the procedure reproduction data according to the first embodiment of the present invention described above with reference to FIGS. 11, 12, and 16 to 18, respectively. The storage processing and the application failure reproduction processing are the same as those in FIG.

  FIGS. 19 to 21 are flowcharts showing application failure reproduction processing and system load state variation processing flow according to the second embodiment of the present invention. Steps S81 to S86 in FIG. 19, steps S91 to S101 in FIG. 20, and steps S102 to S108 in FIG. 21 show the reproduction process of the application failure, and steps S87 to S90 in FIG. Indicates. The application failure reproduction process shown in steps S81 to S86 and steps S91 to S108 is the application failure reproduction process shown in FIGS. 13 to 15 (steps S31 to S40 in FIG. 13 and steps S41 to S47 in FIG. 14). , And the processing shown in steps S48 to S54 in FIG. 15), the description thereof will be omitted, and the fluctuation processing of the system load state will be described below.

  After the application is started in step S86 in FIG. 19, the system load changing unit 6 performs network usage matching processing (step S87). The system load changing unit 6 performs HDD access amount matching processing (step S88). The system load changing unit 6 performs a process for adjusting the memory usage (step S89). Then, the system load changing unit 6 performs CPU usage rate adjustment processing (step S90), and proceeds to step S91 in FIG.

  FIG. 22 is a diagram for explaining the details of the network usage matching process in step S87 of FIG. First, the network usage fluctuation unit 64 of the system load fluctuation unit 6 acquires the analysis result of the entry that is the current processing target of the procedure reproduction data from the procedure reproduction data analysis processing unit 51 of the procedure reproduction unit 5, and the entry The network usage amount (the network usage amount of the procedure reproduction data) set in (1) is acquired (step S111). Next, the network usage amount acquisition unit 68 acquires the current network usage amount of the system from the OS 1 (step S112). The network usage amount variation means 64 compares the network usage amount of the procedure reproduction data acquired in step S111 with the current network usage amount acquired in step S112 (step S113).

  The network usage amount changing means 64 determines whether the network usage amount of the procedure reproduction data acquired in step S111 is equal to the current network usage amount acquired in step S112 (step S114). If the network usage amount changing means 64 determines that the network usage amount of the procedure reproduction data is equal to the current network usage amount, the processing is terminated.

  When the network usage variation means 64 determines that the network usage amount of the procedure reproduction data is not equal to the current network usage amount, the network usage variation means 64 determines that the network usage amount of the procedure reproduction data is the current network usage. It is determined whether the amount is larger (step S115). When the network usage fluctuation means 64 determines that the network usage of the procedure reproduction data is larger than the current network usage, the network usage fluctuation means 64 activates a predetermined process for accessing the network, thereby The usage amount is increased (step S116), and the process returns to step S112. When the network usage variation unit 64 determines that the network usage amount of the procedure reproduction data is not larger than the current network usage amount, the network usage variation unit 64 selects an application using the network other than the target application. By stopping, the network usage is reduced (step S117), and the process returns to step S112.

  FIG. 23 is a diagram for explaining the details of the HDD access amount matching processing in step S88 of FIG. First, the HDD access amount fluctuation means 63 of the system load fluctuation section 6 acquires the analysis result of the entry that is the current processing target of the procedure reproduction data from the procedure reproduction data analysis processing means 51 of the procedure reproduction section 5, and the entry The HDD access amount (the HDD access amount of the procedure reproduction data) set in (1) is acquired (step S121). Next, the HDD access information acquisition unit 67 acquires the current HDD access amount of the system from the OS 1 (step S122). The HDD access amount changing means 63 compares the HDD access amount of the procedure reproduction data acquired in step S121 with the current HDD access amount acquired in step S122 (step S123).

  The HDD access amount changing means 63 determines whether or not the HDD access amount of the procedure reproduction data acquired in step S121 is equal to the current HDD access amount acquired in step S122 (step S124). If the HDD access amount changing means 63 determines that the HDD access amount of the procedure reproduction data is equal to the current HDD access amount, the process is terminated.

  If the HDD access amount changing unit 63 determines that the HDD access amount of the procedure reproduction data is not equal to the current HDD access amount, the HDD access amount changing unit 63 determines that the HDD access amount of the procedure reproduction data is the current HDD access. It is determined whether the amount is larger (step S125). When the HDD access amount changing unit 63 determines that the HDD access amount of the procedure reproduction data is larger than the current HDD access amount, the HDD access amount changing unit 63 activates a predetermined process for accessing the HDD, thereby The access amount is increased (step S126), and the process returns to step S122. When the HDD access amount changing unit 63 determines that the HDD access amount of the procedure reproduction data is not larger than the current HDD access amount, the HDD access amount changing unit 63 selects an application accessing the HDD other than the target application. By stopping, the HDD access amount is decreased (step S127), and the process returns to step S122.

  FIG. 24 is a diagram for explaining the details of the memory usage matching process in step S89 of FIG. First, the memory usage fluctuation unit 62 of the system load fluctuation unit 6 acquires the analysis result of the entry that is the current processing target of the procedure reproduction data from the procedure reproduction data analysis processing unit 51 of the procedure reproduction unit 5, and the entry The memory usage amount (the memory usage amount of the procedure reproduction data) set in (1) is acquired (step S131). Next, the memory resource state acquisition unit 66 acquires the current memory usage of the system from the OS 1 (step S132). The memory usage fluctuation means 62 compares the memory usage of the procedure reproduction data acquired in step S131 with the current memory usage acquired in step S132 (step S133).

  The memory usage variation means 62 determines whether the memory usage of the procedure reproduction data acquired in step S131 is equal to the current memory usage acquired in step S132 (step S134). If the memory usage changing means 62 determines that the memory usage of the procedure reproduction data is equal to the current memory usage, the processing is terminated.

  When the memory usage changing means 62 determines that the memory usage of the procedure reproduction data is not equal to the current memory usage, the memory usage changing means 62 determines that the memory usage of the procedure reproduction data is the current memory usage. It is determined whether the amount is larger (step S135). When the memory usage changing unit 62 determines that the memory usage of the procedure reproduction data is larger than the current memory usage, the memory usage changing unit 62 starts a predetermined memory acquisition process for executing the memory acquisition process. As a result, the memory usage is increased (step S136), and the process returns to step S132. When the memory usage changing unit 62 determines that the memory usage of the procedure reproduction data is not larger than the current memory usage, the memory usage changing unit 62 stops the currently activated applications other than the target application. As a result, the memory usage is reduced (step S137), and the process returns to step S132.

  FIG. 25 is a diagram for explaining the details of the CPU usage rate matching process in step S90 of FIG. First, the CPU load fluctuation unit 61 of the system load fluctuation unit 6 acquires the analysis result of the entry that is the current processing target of the procedure reproduction data from the procedure reproduction data analysis processing unit 51 of the procedure reproduction unit 5, and stores it in the entry. The set CPU usage rate (CPU usage rate of the procedure reproduction data) is acquired (step S141). Next, the CPU usage rate acquisition unit 65 acquires the current CPU usage rate from the OS 1 (step S142). The CPU load changing means 61 compares the CPU usage rate of the procedure reproduction data acquired in step S141 with the current CPU usage rate acquired in step S142 (step S143).

  The CPU load changing unit 61 determines whether the CPU usage rate of the procedure reproduction data acquired in step S141 is equal to the current CPU usage rate acquired in step S142 (step S144). If the CPU load changing means 61 determines that the CPU usage rate of the procedure reproduction data is equal to the current CPU usage rate, the process is terminated.

  When the CPU load changing unit 61 determines that the CPU usage rate of the procedure reproduction data is not equal to the current CPU usage rate, the CPU load changing unit 61 determines that the CPU usage rate of the procedure reproduction data is greater than the current CPU usage rate. It is determined whether it is larger (step S145). When the CPU load changing unit 61 determines that the CPU usage rate of the procedure reproduction data is larger than the current CPU usage rate, the CPU load changing unit 61 increases the CPU usage rate by starting a predetermined CPU calculation process. (Step S146) and the process returns to Step S142. When the CPU load changing unit 61 determines that the CPU usage rate of the procedure reproduction data is not larger than the current CPU usage rate, the CPU load changing unit 61 stops the currently activated application other than the target application. Thus, the CPU usage rate is decreased (step S147), and the process returns to step S142.
