  The present invention relates to an information collecting apparatus that collects information indicating the state of an information processing apparatus in operation.

  In a general information processing apparatus, for example, when a failure occurs while an OS (Operating System) is operating, an information collection function provided in the OS collects information for analyzing the failure. Therefore, if a failure occurs before the start of the OS is completed, there is a problem that the information collecting function cannot collect information.

  As a technique related to dealing with this problem, Patent Document 1 discloses a technique in which a computer system collects information to be output on a screen before powering on and before starting an OS.

  The technique disclosed in Patent Document 1 is a technique for collecting information that the computer system outputs to the screen before the OS is started. However, since there are many failures that are difficult to analyze from the information output on the screen, the information collected by such technology is sufficient information to analyze the failure. I can't say that.

  The technique disclosed in Patent Document 2 is a technique for performing a memory dump when an abnormality occurs when the information processing apparatus performs a boot process. However, since there are many failures that are difficult to analyze from the information stored in the memory, the information collected by such technology is sufficient information to analyze the failure. I can't say that.

  Furthermore, the technique disclosed in Patent Document 3 is a technique in which a virtual machine emulates a real computer system. However, it is generally difficult to construct a virtual environment that is almost equal to the system environment of a real computer system.

<First Embodiment>
FIG. 1 is a block diagram conceptually showing the structure of the information collection system 1 according to the first embodiment. The information collection system 1 according to the present embodiment includes an information collection device 10 and an information processing device 20.

  The information processing apparatus 20 is an apparatus such as a server apparatus. The information processing apparatus 20 includes a CPU (Central Processing Unit) 21, a main storage device 22, an extended storage control device 23, an extended storage device 24, and a screen output control device 25. The CPU 21 executes processing performed in the information processing apparatus 20. The main storage device 22 is a memory that stores data necessary for the CPU 21 to perform processing. The extended storage device 24 is a storage device such as a magnetic disk device, for example, and stores an OS 26. The firmware 27 is stored in a predetermined memory (not shown) provided in the information processing apparatus 20.

  The extended storage control device 23 is a device that controls reading and writing of data with respect to the extended storage device 24, and is a device such as an HBA (Host Bus Adapter). Examples of the HBA include devices such as a SCSI (Small Computer System Interface) controller or a disk array controller. The screen output control device 25 is a device such as a graphics controller that outputs information indicating the state of the information processing device 20 to, for example, a console screen (not shown) when the CPU 21 performs processing. As such a graphics controller, for example, there is an apparatus such as an AGP (Accelerated Graphics Port) video card.

  The information collection device 10 is a device that collects information necessary for analyzing a failure when a failure occurs while the information processing device 20 is operating. The information collection device 10 is a device such as a server device, for example. The information collection apparatus 10 executes a detection process 11, a virtual machine generation execution process 12, and a collection process 13, and constructs a virtual machine 14. In the present embodiment, the information collection device 10 constructs the virtual machine 14, but another information processing device may construct the virtual machine 14.

  Note that the program for executing the detection process 11, the virtual machine generation execution process 12, and the collection process 13 may be built in the information collection apparatus 10 as in the case of general firmware, or a USB (Universal Serial Bus). It may be provided by being stored in a boot device such as a memory.

  In addition, the detection process 11, the virtual machine generation execution process 12, and the collection process 13 can be realized by a dedicated HW (hardware) (electronic circuit). In other words, the information collection device 10 may be an HW having a function equivalent to these processes and including a detection unit, a virtual machine generation execution unit, and a collection unit.

  FIG. 2 illustrates a hardware configuration of the information collection apparatus 10 according to the present embodiment. The execution environment described below can be adopted not only in this embodiment but also in each embodiment described later.

  As illustrated in FIG. 2, the information collection apparatus 10 includes a CPU 901, a ROM (Read_Only_Memory) 902, a RAM (Random_Access_Memory) 903, a hard disk 904 (storage device), and a communication interface 905 (Interface: hereinafter “I / F”). A reader / writer 908 capable of reading and writing data stored in a storage medium 907 such as a CD-ROM (Compact_Disc_Read_Only_Memory), and an input / output interface 909. These components are connected via a bus 906 (communication line). It is a general computer connected. The input / output interface 909 includes, for example, an input device such as a keyboard and an output device such as a monitor. Note that FIG. 2 shows an example in which the information collecting apparatus 10 includes one of these components, but the information collecting apparatus 10 may include a plurality of these components.

  The information collection apparatus 10 is provided with the detection process 11, the virtual machine generation execution process 12, and the collection process 13 as a computer program, and then reads the computer program into the CPU 901 of the hardware, interprets it, and executes it. . The computer program may be stored in a volatile storage memory (RAM 903) that can be read and written or a nonvolatile storage device such as the hard disk 904.

  In the above-described case, the computer program can be supplied to the hardware by a method of installing in the apparatus via various storage media 907 such as a CD-ROM, or an external method via a communication line such as the Internet. A general procedure can be adopted at present, such as a method of downloading more. In such a case, it can be understood that the present invention is configured by a code constituting the computer program or a storage medium 907 in which the code is stored.

  The detection process 11 refers to the information processing device 20 and detects the specifications of the hardware device, the OS 26, and the firmware 27 included in the information processing device 20 as specification information. In this embodiment, the hardware devices are a CPU 21, a main storage device 22, an extended storage control device 23, an extended storage device 24, and a screen output control device 25.

  The specification information includes, for example, the model name of the CPU 21, the capacity of the main storage device 22, the type and capacity of the storage device included in the extended storage device 24, the type of device related to the screen output control device 25, and the OS 26 and firmware 27. Information indicating the device environment including a version number and the like. The detection process 11 may detect information indicating the contents of the device environment as the specification information. Or the detection process 11 may detect the identifier which can identify an apparatus environment as specification information. The identifier may be given to each hardware device and software, or may be given to a device environment that is a combination of a plurality of hardware devices and software.

  The detection process 11 inputs the detected specification information to the virtual machine generation execution process 12. For example, when the information collection apparatus 10 is an apparatus using Linux (registered trademark) as the OS, the detection processing 11 realizes this function by using a “dcodecode” command, an “lspci” command, or the like.

  The virtual machine generation execution process 12 constructs a virtual machine 14 in the information collection device 10 based on the specification information input from the detection process 11. The virtual machine 14 is a virtualization platform that can perform emulation related to processing performed by the information processing apparatus 20.

  The virtual machine generation execution process 12 stores an identifier that can identify the device environment and source code information that describes the virtual machine that realizes the operation of the device environment identified by the identifier. This source code information is information created by an engineer or the like limited to individual hardware devices and software, or individual device environments. The virtual machine generation execution process 12 constructs the virtual machine 14 based on the source code information associated with the identifier input from the detection process.

  The virtual machine 14 includes a virtual CPU 140, a virtual main storage device 141, a virtual extended storage control device 142, a virtual extended storage device 143, and a virtual screen output control device 144.

  The virtual CPU 140 implements the functions provided in the CPU 21 in the virtual machine 14. The virtual main storage device 141 implements the functions of the main storage device 22 in the virtual machine 14. The virtual extended storage control device 142 implements the functions of the extended storage control device 23 in the virtual machine 14. The extended storage control device 143 implements the functions of the extended storage device 24 in the virtual machine 14. The virtual screen output control device 144 implements the functions provided in the screen output control device 25 in the virtual machine 14. The virtual OS 145 is an OS that virtualizes the OS 26. The virtual firmware 146 is firmware obtained by virtualizing the firmware 27.

  The virtual machine generation execution process 12 executes the constructed virtual machine 14. For example, when the information collection apparatus 10 is an apparatus using Linux as an OS, the virtual machine generation execution process 12 realizes this function by using a “qemu-kvm” command. The qemu-kvm command has a function of executing emulation related to a function of a device that actually exists.

  The virtual machine generation execution process 12 gives an instruction not to collect information regarding at least one of the CPU 21, the main storage device 22, the extended storage control device 23, the extended storage device 24, and the screen output control device 25. May be given by a system administrator or the like. In this case, the virtual machine generation execution process 12 uses output data output from the device, which is an expected value that is uniquely determined from data input to the device without performing emulation of the device. Alternatively, if there is no particular problem, the virtual machine generation execution process 12 may pass through the input / output related to the device.

  The collection process 13 collects information held by the virtual machine 14 while the virtual machine generation execution process 12 is executing the virtual machine 14. The virtual machine 14 is data stored in a memory included in the information collection device 10. Therefore, the collection process 13 can read information held by the virtual machine 14 from a predetermined address in a memory included in the information collection apparatus 10.

  The collection process 13 collects information stored at a predetermined address of the virtual main storage device 141 and information stored at a predetermined address of the virtual extended storage device 143. The collection process 13 stores the information collected from the virtual main storage device 141 in the main storage device 22 when instructed by a user or the like, and passes the information collected from the virtual extended storage device 143 via the extended storage control device 23. And stored in the extended storage controller 24.

  The collection process 13 also collects information output from the virtual screen output device 144 as a moving image such as MPEG (Moving Picture Experts Group) format or a still image such as JPEG (Joint Photographic Experts Group) format. For example, when the information collection apparatus 10 is an apparatus using Linux as an OS, the collection process 13 realizes this function by using a “virt-manager” command or the like. When instructed by the user or the like, the collection process 13 inputs the collected data of moving images and still images to the screen output control device 25. The screen output control device 25 processes these input data and outputs them to the console screen.

  The collection process 13 outputs information collected from the virtual machine 14 as a collection result file 130. The storage destination for storing the collection result file 130 may be a storage device locally connected to the information collection device 30, or may be a storage device that the information collection device 30 can access via a communication network.

  Next, the operation (process) of the information collection system 1 according to the present embodiment will be described in detail with reference to the flowchart of FIG.

  The detection process 11 detects specification information related to the information processing apparatus 20 (step S101). The detection process 11 inputs usage information to the virtual machine generation execution process 12 (step S102). The virtual machine generation execution process 12 constructs the virtual machine 14 in the information collection device 10 based on the specification information (step S103).

  When information collection is performed for all detected hardware devices (No in step S104), the virtual machine generation execution processing 12 executes emulation for the virtual machine 14 for all detected hardware devices (step S104). S105). The collection process 13 collects information held by the virtual machine 14 for all detected hardware devices (step S106). The collection process 13 outputs the collected information as a collection result file 130 (step S109), and the entire process ends.

  Of the detected hardware devices, regarding any hardware device, when information collection is not performed (Yes in step S104), the virtual machine generation execution process 12 performs the detected hardware excluding the hardware device. For the device, emulation for the virtual machine 14 is executed (step S107). The collection process 13 collects information held by the virtual machine 14 regarding the detected hardware devices excluding the hardware device (step S108), and the process proceeds to step S109.

  Even if it is difficult to directly collect failure information necessary for analyzing a failure that has occurred in an information processing device from the information processing device, the information collection system 1 according to the present embodiment is concerned with the failure information. Can be collected. The reason is that the virtual machine generation execution process 12 constructs a virtual machine 14 limited to the device environment of the information processing apparatus 20 based on the specification information related to the information processing apparatus 20 detected by the detection process 11, and the collection process 13 This is because the information held by the virtual machine 14 is collected.

  In the information processing apparatus, for example, when a failure occurs before the activation of the OS is completed, the information collection function included in the OS cannot collect information necessary for failure analysis. In such a case, for example, a method for collecting information necessary for failure analysis from a virtual machine after building a virtual machine using a general-purpose virtualization infrastructure, reproducing a failure related to the virtual machine Can be considered. However, it is generally difficult to construct a virtual environment that is almost equal to the system environment of a real computer system. Therefore, the information collected from such a virtual machine cannot be said to be sufficient information for analyzing a failure. Alternatively, it may be difficult for the virtual machine to reproduce the failure itself.

  On the other hand, in the information collection system 1 according to the present embodiment, the detection process 11 detects specification information indicating the device environment related to the information processing device 20. Then, the virtual machine generation execution process 12 constructs a virtual machine 14 limited to the device environment based on the specification information detected by the detection process 11. The virtual machine 14 is constructed based on source code information and the like necessary for constructing the virtual machine 14 created by an engineer who is familiar with the device environment related to the information processing apparatus 20. Therefore, the virtual machine 14 can emulate the device environment related to the information processing device 20 with higher accuracy than a general-purpose virtualization platform. The collection process 13 collects a wide range of information held by the virtual machine 14. Thereby, even if it is difficult for the information collection system 1 according to the present embodiment to collect failure information necessary for analyzing a failure that has occurred in the information processing device directly from the information processing device, Such failure information can be collected.

  When it is determined that there is no problem with at least one of the hardware devices used when the information processing device 20 starts up the OS 26, the virtual machine generation execution processing 12 according to the present embodiment. The information for identifying the type of the hardware device is input by the user or the like. In this case, the virtual machine generation execution processing 12 does not perform emulation for the hardware device, uses the expected value regarding the output information, or passes through the input / output. Then, the collection process 13 collects information from the virtual machine 14 regarding the hardware devices excluding the hardware device. Thereby, the information collection system 1 according to the present embodiment can reduce the load applied when the information collection apparatus 10 collects information using the virtual machine 14.

  Furthermore, the collection process 13 according to the present embodiment also stores information collected from the virtual main storage device 141 in the main storage device 20. The collection process 13 also stores information collected from the virtual extended storage device 143 in the extended storage device 24. The collection process 13 also inputs information collected from the virtual screen output control device 144 to the screen output control device 25. As a result, the user can use the information processing apparatus 30 to check the contents of the information collected from the virtual machine 14. Therefore, the information collection system 1 according to the present embodiment can improve the efficiency when the user performs the failure analysis work.

Note that the case of using the information collection system 1 according to the present embodiment is not limited to the case of analyzing a failure that occurs during the operation of the information processing apparatus 20. For example, the information collection system 1 may be used to collect information necessary for analyzing a problem such as a performance problem.
(Modification of the first embodiment)
FIG. 4 is a block diagram conceptually showing the structure of a modification of the information collection system according to the first embodiment. In FIG. 4, the functions of the constituent elements to which the same numbers as those in FIG. 1 are provided are the same as those in the first embodiment, and thus the description of these constituent elements is omitted.

  The information collection system 2 according to the present embodiment includes an information collection device 30 and an information processing device 40.

  The information processing apparatus 40 includes a BMC (Baseboard Management Controller) 48. For the information processing apparatus 40, the BMC 48 performs processing related to general system control such as configuration change processing and failure processing. The BMC 48 operates without depending on the OS 26. The BMC 48 includes a screen output control device 45.

  In the present modification, the virtual machine generation execution process 32 does not perform emulation related to the virtual screen output control device 344 in the virtual machine 34, and the input information to the virtual screen output control device 344 is used as it is. Pass through as output information from. The virtual machine generation execution process 32 inputs the output information that has passed through to the screen output control device 45.

  The screen output control device 45 processes the input information and outputs it to the console screen. The screen output control device 45 also transmits information output to the console screen to the collection processing 33 using a communication method such as “Block Transfer Interface” provided by the BMC 48.

  The collection process 33 outputs the information obtained from the screen output control device 45 together with the information collected from the virtual machine 34 as a collection result file 130.

  Even if it is difficult to directly collect failure information necessary for analyzing a failure that has occurred in the information processing device from the information processing device, the information collection system 2 according to the present modification has such failure information. Can be collected. The reason is that the virtual machine generation execution process 32 constructs a virtual machine 34 limited to the device environment of the information processing apparatus 40 based on the specification information related to the information processing apparatus 40 detected by the detection process 11, and the collection process 33 This is because the information held by the virtual machine 34 is collected.

  Further, the virtual machine generation execution process 32 according to the present modification does not perform emulation with respect to the screen output control device 45, and inputs output information from the virtual machine 34 to the screen output control device 45 that is a real machine. The collection process 33 processes the information acquired from the screen output control device 45 in the same manner as the information collected from the virtual machine 34. Therefore, the information collection system 2 according to the present modification effectively uses the screen output control device 45, which is a real machine, to reduce the load applied when the information collection device 10 uses the virtual machine 14 to collect information. Can be suppressed.

  Note that the actual machine that is effectively used by the information collection system 2 according to the present modification is not limited to the screen output control device 45. The information collection system 2 may effectively utilize another device included in the information processing device 40.

<Second Embodiment>
FIG. 5 is a block diagram conceptually showing the structure of the information collecting apparatus 50 of the second embodiment.

  The information collection device 50 according to this embodiment includes a detection unit 51, a virtual machine generation execution unit 52, and a collection unit 53.

  The detection unit 51 includes specification information on specifications of one or more, for example, n hardware devices 61-1 to 61-n included in the first information processing device 60 and software 62 executed by the hardware devices 61-1 to 61-n. Detect as.

  The virtual machine generation execution unit 52 constructs the virtual machine 71 in the second information processing apparatus 70 based on a predetermined standard. The virtual machine 71 is a virtual machine that realizes the operation of the device environment limited to the device environment determined by the specification information. The virtual machine generation executing unit 52 executes the virtual machine 71 after constructing the virtual machine 71.

  The collection unit 51 collects information held by the virtual machine 71 from the second information processing apparatus 70 while the virtual machine generation execution unit 52 is executing the virtual machine 71.

  Even when it is difficult to directly collect failure information necessary for analyzing a failure that has occurred in the information processing device from the information processing device, the information collection device 50 according to the present embodiment is related to the failure information. Can be collected. The reason is that the virtual machine generation execution unit 52 builds a virtual machine 71 limited to the device environment of the first information processing device 60 based on the specification information about the first information processing device 60 detected by the detection unit 51. This is because the collection unit 53 collects information held by the virtual machine 71.
