Description

  The present invention relates to a computer operation information recording apparatus, and more particularly, to a computer operation information recording apparatus that records an operation state of hardware of a computer when a program is executed on the computer.

  Conventionally, there are two methods for recording computer operation information in a high-load state, an abnormal state, etc. of a computer: a recording method by software and a recording method by hardware. By analyzing the data recorded by the software or hardware, that is, operation information, the user who develops the computer program, etc., confirms the operation of the computer, analyzes the various states of the computer, and develops the development program, etc. Can be optimized.

  When computer operation information is recorded by software, load status information is acquired during the execution of each program by an operating system (hereinafter referred to as OS) or an application program (hereinafter also simply referred to as application), and events that occur for the program The operation information indicating the operation state of the software such as recording is recorded. In addition, when recording the operation state of the computer by hardware, operation information indicating the operation state of the hardware is recorded by a logic analyzer or the like.

  In general, recording by software records various pieces of operation information in the operation cycle of the software. Therefore, recording by software results in recording operation information at a relatively longer time interval than recording by hardware. On the other hand, in the recording by hardware, the operation information of hardware is recorded in the operation cycle of the hardware as a general rule. Therefore, the recording by hardware is the operation information at a relatively short time interval than the recording by software. It becomes a record.

  One of the recording methods by software is to generate an interrupt when a measurement event (for example, execution of a specific function) occurs for a certain number of times exceeding a certain threshold, and use the interrupt handler to generate the number of interrupts. Japanese Patent Laid-Open No. 2005-215816 proposes a technique for performing performance profiling by counting.

  In addition, as one of the recording methods by hardware, a technique for selecting a frequently executed instruction whose number of calls exceeds a predetermined threshold and performing hardware performance profiling on the selected instruction is also disclosed in US Pat. This is proposed in Japanese Patent No. 5896538.

  However, since software recording and hardware recording were performed separately from each other, in the event of abnormal conditions, high load conditions, etc., the same event must be reproduced and recorded separately again. There was a need to do.

Furthermore, since it is often unknown when an abnormal state, a high load state, etc. occurs, the effort to reproduce such a state is great, and in addition, it is reproduced and recorded in two methods. Even when it is performed, labor and cost for matching data acquired by different methods at the time of data analysis are large.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
First, based on FIG. 1, the structure of the computer operation information recording apparatus concerning the 1st Embodiment of this invention is demonstrated. FIG. 1 is a block diagram for explaining the system configuration of the computer operation information recording apparatus according to this embodiment.

A buffer memory (hereinafter also simply referred to as a buffer) 23 is provided. Although not shown, the hardware layer 11 includes an input / output interface unit, a main memory, and the like. For example, the hardware layer 11 is composed of one semiconductor chip.

  The software layer 12 includes an OS 31, a monitor unit 32 included in the OS 31, and a plurality of application programs (hereinafter simply referred to as applications) 33 executed on the OS 31. The application 33 includes a setting display unit 34 and a plurality of user programs 35.

  The computer operation information recording apparatus 1 is, for example, a computer such as a personal computer (PC) or a dedicated machine that executes a user program 35 that is a development program. In addition to the CPU 21, the computer operation information recording apparatus 1 includes a ROM, a RAM, various interfaces, and the like. The computer information recording apparatus 1 includes a man-machine interface (hereinafter abbreviated as MMI) such as an input device such as a keyboard and a mouse, a display device such as a screen and a printer, although not shown. Furthermore, an external storage device such as a hard disk device can be connected to the computer information recording device 1.

FIG. 2 is a diagram for explaining functions of the computer operation information recording apparatus 1 according to the present embodiment. To describe the overall operation, the OS 31 reads the user program 35 from the program file 41, reads the setting information from the setting file 42, and causes the CPU 21 to execute the read user program 35.
The setting information includes conditions for recording operation information indicating the operation state of hardware, that is, information on recording conditions. The setting information is information relating to the entire computer system in which the user program 35 is executed as shown in FIG. 1, and may be not only a condition indicating the software state in the computer system but also a condition indicating the hardware state in the computer system. .

  The monitor unit 32 monitors the state of the entire system when the user program 35 is executed, and further monitors the execution state of each process 35 a executed corresponding to the source code of the user program 35. The monitor unit 32 monitors whether the recording condition set in the read setting information is satisfied during execution of the user program 35.

  When the execution of the user program 35 is started, the monitor unit 32 records operation information (hereinafter also referred to as software operation information) indicating operation states of various programs being executed by the user program 35.

Further, when the monitor unit 32 detects that the recording condition set in the setting file 42 is satisfied, the operation information indicating the operation state of hardware (hereinafter also referred to as hardware operation information) is referred to as software operation information. Record in association. The recorded software operation information and hardware operation information are read by the setting display unit 34 and output to the data file 43 as result data or to the display unit 44 such as a liquid crystal display (LCD). Is displayed.
As will be described later, when the monitor unit 32 detects that the recording condition set in the setting file 42 is satisfied, the monitor unit 32 may simultaneously start recording the software operation information and the hardware operation information. .

  In addition, the setting display unit 34 uses the MMI to set setting information in a setting file 42 (to be described later), display and change the set setting information on the screen of the display unit 44, and acquire the setting information. It is a processing unit for executing processing for outputting software operation information and hardware operation information to the data file 43 or the display unit 44.

  The program file 41, the setting file 42, and the data file 43 are provided in, for example, an external storage device (not shown).

  This will be described more specifically. The monitor unit 32 monitors the operation of all programs such as the OS 31 and the user program 35. Software operation information is obtained by periodically recording the value of the program counter (PC) to obtain program operation point, that is, operation address information, and analyzing the operation point in association with the source code of the program file. Is obtained by Thereby, the monitor part 32 can determine the program, function, address, etc. in operation, for example.

  Furthermore, the monitor unit 32 records the acquired software operation information in the data file 43, and when it is determined that the recording condition is satisfied, the monitor unit 32 outputs the start signal or the storage command to thereby cause the hardware monitor 22 to be output. Start and start recording of hardware operation information during operation. For example, the recording condition is a condition such as a threshold value for the number of executions, an execution ratio, etc. for a specific instruction in the user program.

  The recording conditions set in the setting file 42 include not only the conditions regarding the operation state of the user program to be executed, such as the number of executions of a specific instruction in the user program, but also the user program as described above. It may be a condition about the state of the entire computer system to be executed.

  The hardware monitor 22 can store the hardware operation information in the buffer 23 as time series data by continuously storing the hardware operation information in the buffer 23 at a predetermined timing.

  The hardware monitor unit 22 has a so-called performance monitor function that monitors and acquires hardware operation information in accordance with a start command or a store command from the monitor unit 32 of the OS 31 and records it in the buffer 23 as time series data. . Specifically, the hardware monitor unit 22 obtains data of a plurality of registers in the CPU 21 set in advance continuously at a predetermined timing a plurality of times, thereby buffering hardware operation information as time series data. 23.

Here, the predetermined timing may be set in advance by a user or the like, or may be a time interval that the hardware monitor unit 22 has in advance. The hardware operation information becomes time-series data because the hardware operation information is continuously acquired at the predetermined timing once the storage instruction is received.
Even after it is determined that the recording condition is satisfied, the software operation information is continuously acquired, and thus becomes time-series data.

  As described above, the monitor unit 32 always stores the software operation information while the user program 35 is being executed. When the monitor unit 32 determines that the set recording condition is satisfied, the computer 32 performs calculation according to the timing when the recording condition is satisfied. Recording of hardware operation information is started as information on the operation state.

  Therefore, software operation information and detailed hardware operation information having a shorter time interval than the software operation information are recorded in association with each other. The hardware operation information recorded in the buffer 23 is read by the setting display unit 34 and output and recorded in the data file 43 of the external storage device, or is output and displayed on the display unit 44.

Next, the configuration of the monitor unit 32 will be described.
FIG. 3 is a block diagram for explaining the configuration of the monitor unit 32. The monitor unit 32 includes a program file reading unit 51, a user process monitoring unit 52, a setting file reading / writing unit 53, a hardware monitor control (HW monitor control unit in the figure) 54, and a hardware operation information receiving unit.

Specifically, the state of the entire system is also monitored by associating the program from the program file reading unit 51 at the source code level and monitoring the operation of each process 35a. The user process monitoring unit 52 supplies information on the operation state of each process of the user program 35 obtained by monitoring to the hardware monitor control unit 54.
The association at the source code level of the program may be performed by the program file reading unit 51.

The setting file reading / writing unit 53 is a processing unit that reads setting information from the setting file 42 and writes setting information to the setting file 42.
Specifically, setting information from the setting display unit 34 input by the user using the MMI is input to the setting file reading / writing unit 53 via a setting information receiving unit 56 described later. The setting file reading / writing unit 53 writes the input setting information in the setting file 42. Further, the setting file reading / writing unit 53 reads the setting information designated by the user using the MMI and written in the setting file 42, and sends it to the setting display unit 34 via the setting information receiving unit 56. Output. The user can confirm and change the setting information input to the setting display unit 34 using the MMI on the screen. The setting file reading / writing unit 53 constitutes a condition setting unit.

The hardware monitor control unit 54 activates the hardware monitor unit 22 based on the information regarding the operation state from the user process monitoring unit 52 and the setting information from the setting file reading / writing unit 53, and the hardware monitoring unit 22 is a processing unit for acquiring hardware operation information.
Specifically, when the hardware monitor control unit 54 receives information on the operation state of each process of the user program 35 from the user process monitoring unit 52, the hardware monitor control unit 54 compares the setting information from the setting file reading / writing unit 53. Then, it is determined whether or not the recording condition defined in the setting information is satisfied. When the hardware monitor control unit 54 compares the setting information acquired from the setting file reading / writing unit 53 described later with the operation of the user program 35 or its process 35a and determines that the recording condition is satisfied, Start recording hardware operation information.

  The software operation information may be directly written into the data file 43 by the user process monitoring unit 52 or the hardware monitor control unit 54 during execution of the user program 35, or set with the operation information transmission unit 57 described later. The data file 43 may be written via the display unit 34. The user process monitoring unit 52 or the hardware monitor control unit 54 constitutes a software execution information recording execution unit.

  For recording hardware operation information, the hardware monitor control unit 54 outputs a storage instruction to the hardware monitor unit 22, and the data of one or more predetermined registers of the CPU 21 is stored in the buffer 23 as hardware operation information. This is done by instructing to record. The hardware monitor control unit 54 constitutes a recording condition determination unit and a recording execution unit for hardware operation information.

The hardware operation information receiving unit 55 is a processing unit for reading and receiving the hardware operation information recorded in the buffer 23 of the hardware monitor unit 22.
Specifically, the hardware operation information reception unit 55 is a processing unit that receives hardware operation information recorded in the buffer 23 and outputs the hardware operation information to the operation information transmission unit 57.

  As described above, the setting information receiving unit 56 outputs the setting information received from the setting display unit 34 to the setting file reading / writing unit 53 or reads the setting information read via the setting file reading / writing unit 53. It is a processing unit for outputting information to the setting display unit 34.

The operation information transmission unit 57 is a processing unit that supplies the hardware operation information from the hardware operation information reception unit 55 to the setting display unit 34.
Specifically, the operation information transmitting unit 57 outputs the recorded hardware operation information to the setting display unit 34 in order to display the recorded hardware operation information on the screen of the display unit 44 in response to an instruction from the user. .

Here, the configuration of the buffer 23 will be described. FIG. 4 is a configuration diagram illustrating a configuration example of the buffer 23.
The buffer 23 is a plurality of data in which both the data of the event generated inside the CPU 21 and the data of a plurality of registers such as control registers in the CPU 21 acquired by the hardware monitor unit 22 are recorded. It is configured to include a buffer area. The buffer 23 stores data of n registers (n is a positive integer of 1 or more) from the registers a1 to an in the CPU 21 by m (m is an integer of 2 or more) or m times. It includes a plurality of buffer areas that can be stored. The registers a1 to an in the CPU 21 for acquiring hardware operation information are respectively designated or set in advance by the user.

  More specifically, the buffer 23 includes m buffer arrays BA1 to BAm. Each buffer array BAi has n buffer areas for recording data (d1i, d2i, d3i, d4i,..., Dni) of a plurality of registers corresponding to the registers a1 to an at a single timing. (I is an integer from 1 to m). At the first timing t1, n data (d11, d21, d31, d41,..., Dn1) of registers a1 to an are recorded in the buffer array BA1. At the second timing t2, n data (d12, d22, d32, d42,..., Dn2) of registers a1 to an are recorded in the buffer array BA2. Similarly, at the last timing tm, n data (d1m, d2m, d3m, d4m,..., Dnm) of registers a1 to an are recorded in the buffer array BAm.

The hardware monitor unit 22 has a built-in control circuit that continuously acquires data of each register at a predetermined cycle timing. Therefore, when receiving a storage command that is an instruction to record hardware operation information, the hardware monitor unit 22 continuously acquires data in each register at a predetermined cycle timing. As a result, the time series data of each register is recorded in the buffer 23 shown in FIG.
When the storage area of the buffer 23 is filled with hardware operation information for m times, the recording of the hardware operation information ends. Note that the recording of the hardware operation information may be terminated when the recording condition is not satisfied. Moreover, the recording of the software operation information may be terminated at the end of the recording of the hardware operation information, or may be continued.

  Accordingly, each register data acquired at a predetermined timing is recorded in the buffer 23 as time-series data over a predetermined time. In other words, the buffer 23 is a memory having a plurality of storage areas for recording data of each register as time-series data obtained by obtaining a plurality of times at a predetermined timing over a predetermined time. .

Next, the operation will be described.
FIG. 5 is a flowchart showing an example of the processing flow of the monitor 32. Prior to the execution of the processing of FIG. 5, the user uses the MMI to specify the user program 35 for recording the computer operation information, to write the recording condition setting file 42 for recording the operation information, and One or more registers of the CPU 21 for recording hardware information for the hardware monitor unit 22 are designated in advance.

  When the designated user program 35 is executed, recording of software operation information is started, and the processing of FIG. 5 is executed. Prior to the execution, the hardware monitor control unit 54 reads the recording condition information from the setting file 42 by the setting file reading / writing unit 53 and acquires the recording condition information.

The monitor 32 executes the specified user program 35, and the user process monitoring unit 52 of the monitor 32 monitors the operating state of all software being executed including the OS 31 and the user program 35, and the hardware monitor. The control unit 54 determines whether or not the recording condition from the setting file reading / writing unit 53 is satisfied based on the operation state information from the user process monitoring unit 52 (step S1). For example, when the number of executions of a predetermined instruction is monitored as the operation state of the program and the number of executions is set as the recording condition, it is determined whether or not the predetermined instruction has been executed for the set number of times. If the command is executed the set number of times, it is determined that the recording condition is satisfied. The processing in step S1 constitutes a recording condition determination unit executed by the hardware monitor control unit 54.
If the recording condition is not satisfied, the process does not proceed to the next process and continues the process of step S1.

  When the recording condition is satisfied, the hardware monitor control unit 54 outputs an instruction to record the hardware operation information in the buffer 23 by outputting a storage command to the hardware monitor unit 22 (step S2). ).

  The hardware monitor unit 22 instructed to record the hardware operation information acquires the operation information of each register at a predetermined cycle, that is, a cycle timing, and records it in the buffer 23.

  Although the time that can be recorded in the buffer 23 varies depending on the sampling cycle, in the present embodiment, when hardware operation information for m buffer arrays is recorded, the processing in step S2 in FIG. 5 ends.

  Note that it is monitored whether or not the set time set by a separately set timer has been reached, and when the elapsed time from the start of recording reaches the set time, the process of step S2 may be terminated. Alternatively, the recording of the hardware operation information may be terminated when the recording condition is not satisfied. The process of step S2 constitutes a recording execution unit executed by the hardware monitor control unit 54.

  With the above processing, the software operation information and the hardware operation information can be associated with each other based on the elapsed time from the start of the recording of the hardware operation information and the time of the predetermined cycle of the hardware monitor unit 22. it can.

  The recorded software operation information and hardware operation information are displayed on the setting display unit 34 by the user using the MMI, for example, on the display unit 44 as time-series data so that the two operation information can be compared. Can do. In other words, by providing the setting display unit 34, which is software as a user-side tool, with a function as a display unit that displays the recorded software operation information and hardware operation information in comparison, two functions are provided. The user can see the operation information in comparison.

Note that the two pieces of associated operation information, that is, the software operation information and the hardware operation information, for example, can be displayed not only on the screen but also side by side with a printer.
Furthermore, the monitor unit 32 may start recording the software operation information and the hardware operation information at the same time when detecting that the recording condition set in the setting file 42 is satisfied.

  FIG. 6 is a flowchart illustrating an example of a processing flow of the monitor unit 32 when performing the simultaneous recording. The same steps as those in FIG. 5 are denoted by the same step symbols and description thereof is omitted. As shown in FIG. 6, when detecting that the recording condition is satisfied in step S1, the hardware monitor control unit 54 starts recording the software operation information (step S3), and at the same time, the hardware monitor unit A storage instruction is output to 22 (step S2).

  According to the processing of FIG. 6, since the recording of the software operation information and the hardware operation information is started at the same time, based on the elapsed time from the start of the recording and the time of a predetermined cycle of the hardware monitor unit 22. Thus, the software operation information and the hardware operation information can be associated with each other. In the case of FIG. 6, the recording condition is a condition for recording both software operation information and operation information indicating the operation state of the hardware.

  Therefore, since two pieces of operation information related in time can be seen, the user can efficiently optimize the development program and the like.

  As described above, according to the present embodiment, since the recording of hardware operation information is started when a predetermined recording condition is satisfied, it is possible to match two operation information when analyzing the operation information of a computer. Labor and cost can be reduced.

(Second Embodiment)
In the first embodiment, the operating state of software such as an OS and a program such as a process is monitored, and when the monitored state matches a recording condition relating to a predetermined set operating state of the program, Recording of hardware operation information is started so that software operation information and hardware operation information are associated with each other. On the other hand, in the second embodiment, the software event that has occurred for the program being executed is monitored, and when the software event meets a predetermined recording condition, recording of hardware operation information is started. The software operation information and the hardware operation information are associated with each other.

  FIG. 7 is a block diagram for explaining the configuration of the monitor unit 32A according to the second embodiment. Note that the same components as those of the monitor unit 32 in FIG. 3 are denoted by the same reference numerals and description thereof is omitted. The monitor unit 32A includes a software event recording unit 61 and a software event monitoring unit 62.

  The software event recording unit 61 is a processing unit that detects and records software events such as file open errors and page faults during execution of the user program 35. The software event is detected based on, for example, the presence or absence of an interrupt. Software events indicating the operating state of the computer include not only software events related to the OS but also software events related to applications. Accordingly, software events include events such as process switching, disk access, interprocess communication, specific output in an application, application error, and the like in addition to the above-described events.

  Information of the software event detected and recorded is output to the software event monitoring unit 62. The software event monitoring unit 62 supplies the obtained software event information to the hardware monitor control unit 54.

On the other hand, the setting file 42A stores software event information as a recording condition.
When the hardware monitor control unit 54 receives the software event information from the software event monitoring unit 62, the hardware monitor control unit 54 compares the information with the setting information in the setting file 42 from the reading / writing unit 53, and records the setting information. Processing for determining whether or not the condition is satisfied is performed. In the setting file 42, conditions relating to software events that occur during the execution of the program are set as setting information, that is, recording conditions.

  Then, the hardware monitor control unit 54 compares the setting information acquired from the setting file reading / writing unit 53 with the software event information from the software event monitoring unit 62, and determines that the recording condition is satisfied. When it is done, recording of hardware operation information is started.

  For example, the occurrence of an open error in a predetermined file is stored in advance in the setting file 42 as a recording condition, and the hardware monitor control unit 54 monitors software event information from the software event monitoring unit 62, When the event information of the open error of the predetermined file is received, a storage command is output to the hardware monitor unit 22. When the execution of the user program 35 is started, the software event information as information indicating the operation state of the software is sent by the software event recording unit 61, the software event monitoring unit 62, or the hardware monitor control unit 54. It is recorded in the data file 43 as time series data.

  The other processes and operations of the monitor unit 32A are the same as the processes and operations of the monitor unit 32 in the first embodiment.

  The recording conditions set in the setting file 42 may be not only the presence / absence of occurrence of a specific software event, but also conditions such as a threshold for the number of occurrences, occurrence rate, occurrence state, etc. of a specific software event.

  Also in the present embodiment, recording of both software operation information and hardware operation information is started when it is determined that the recording condition related to the software event is satisfied as in the process shown in FIG. You may make it make it.

  As described above, according to the present embodiment, when a predetermined recording condition for a software event is established, recording of hardware operation information is started. Labor and cost for matching can be reduced.

(Third embodiment)
In the first embodiment, the operating state of software such as an OS and processes is monitored, and when the monitored state matches a predetermined recording condition, recording of hardware operation information starts. Thus, the software operation information and the hardware operation information are associated with each other. In the second embodiment, a software event that has occurred for the program being executed is monitored, and when the software event meets a predetermined recording condition, recording of hardware operation information is started, and the software operation is started. The information is associated with the hardware operation information. On the other hand, in this embodiment, the start condition for recording the hardware operation information is the software and process operation such as the OS as in the first embodiment and the operation in the second embodiment. It is possible to select any of the software events that have occurred for the program being executed.

  FIG. 8 is a block diagram for explaining the configuration of the monitor unit 32B according to the third embodiment. The same components as those of the monitor units 32 and 32A in FIGS. 3 and 7 are denoted by the same reference numerals, and description thereof is omitted. The monitor unit 32B includes a program file reading unit 51, a user process monitoring unit 52, a software event recording unit 61, and a software event monitoring unit 62. Furthermore, the monitor unit 32B includes a switching unit 71.

  Based on the switching signal, the switching unit 71 causes the hardware monitor control unit 54 to set the recording condition of the hardware operation information to the operation of software such as the OS and the process as in the first embodiment. This is a processing unit for switching whether to perform based on a software event that has occurred for a program being executed as in the second embodiment. The switching signal can be input or instructed to the switching unit 71 by the user using the MMI.

The user uses the MMI to instruct the switching unit 71 to perform the recording start condition of the hardware operation information based on the operation of software such as the OS and the process as in the first embodiment. When the switching signal to be input is input, the switching unit 71 monitors the operation information from the user process monitoring unit 52 with respect to the hardware monitor control unit 54 and records the operation information from the setting file reading / writing unit 53. An instruction is issued to determine whether the condition is satisfied.
In addition, the user instructs the switching unit 71 to perform the recording start condition of the hardware operation information based on the software event generated for the program being executed as in the second embodiment. When the signal is input, the switching unit 71 monitors the software event information from the software event monitoring unit 62 with respect to the hardware monitor control unit 54 and the software event from the setting file reading / writing unit 53. An instruction is issued to determine whether or not the recording condition for is satisfied.
Other operations are the same as those in the first and second embodiments described above.
As described above, according to the present embodiment, it is determined whether a predetermined recording condition is satisfied with respect to the operation of software such as an OS or a process, and whether a predetermined recording condition is satisfied with respect to a software event. Since it is possible to switch, since the recording of hardware operation information is started when a determination condition desired by the user is satisfied, labor and cost for matching two operation information at the time of analyzing the operation information of the computer Can be reduced.

In the above-described example, the switching of the switching unit 71 is performed by the user using the MMI. However, the switching signal for the switching unit 71 may be switched and output according to a preset time. Good. For example, in a certain first period, recording of hardware operation information and software operation information is started based on a software event, and a second period after the first period is a software such as an OS. Recording of hardware operation information and hardware operation information, and so on. Therefore, a switching signal generated based on a timer (not shown) is input to the switching unit 71.
This is the case, for example, when pursuing the cause while monitoring the overall operation status of the computer when it is unclear whether the cause of the high load on the computer is due to program operation or software events. In addition, it is possible to record the state of the computer when the load is high.

  Furthermore, the switching signal for the switching unit 71 may be switched and output according to the program being executed. For example, when the program X is executed, the recording method of the first embodiment is executed, and when the program Y is executed, the recording method of the second embodiment is executed. In addition, a switching signal corresponding to the program being executed is input to the switching unit 71. As a result, a recording method according to the program being executed can be realized.

  For example, this is a case where it is unclear whether the cause of the high load on the computer is the operation of the program or the software event, but especially when the relationship with the program is known. It is possible to record the state at the time of high load.

  Also in this embodiment, when it is determined that the recording condition is satisfied as in the process shown in FIG. 6, recording of both the software operation information and the hardware operation information is started simultaneously. It may be.

  As described above, the computer operation information recording device of each embodiment described above collects information on the entire system by a software program such as an OS, and the system or program has predetermined conditions (operation load, number of event occurrences, etc.). In such a case, the performance monitor function of hardware such as a CPU is activated to record detailed hardware operation information.

  As a result, for example, it is possible to record hardware and software operation information in the case of an abnormal computer state, a high load state, etc. where it is unknown, so that recording and analysis can be performed by reproducing the event. Costs for time data alignment, etc. can be greatly reduced.

  Each “unit” in this specification is a conceptual one corresponding to each function of the embodiment, and does not necessarily correspond to a specific hardware or software routine on a one-to-one basis. Therefore, in the present specification, the embodiment has been described assuming a virtual circuit block (unit) having each function of the embodiment. In addition, each step of each procedure in the present embodiment may be executed in a different order for each execution by changing the execution order and performing a plurality of steps at the same time, as long as it does not contradict its nature.

  The program for executing the operations described above is recorded or stored in whole or in part on a portable medium such as a floppy disk, CD-ROM, or a storage device such as a hard disk. Can be offered as a program product. The instruction group included in the program is read by the computer, and all or part of the operation is executed. Alternatively, all or part of the program can be distributed or provided as a program product via a communication network. The user can easily realize the computer operation information recording apparatus of the present invention by downloading the program via a communication network and installing it on a computer, or installing it from a recording medium to a computer.

  The present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the present invention.
