It is a schematic block diagram which shows the basic composition of a computer system.

Hereinafter, embodiments will be described in detail with reference to the drawings.
FIG. 1 is a schematic block diagram illustrating a hardware configuration of a computer according to the first embodiment.
The computer 1 includes a CPU 100, a main memory 200, a nonvolatile memory 300, a storage 400, and an interface 500.
The CPU 100 reads a program from the nonvolatile memory 300 or the storage 400, expands it in the main memory 200, and executes processing according to the program.
The nonvolatile memory 300 stores the BIOS01. Examples of the non-volatile memory 300 include an EEPROM (Electrically Erasable Programmable Read-Only Memory), a flash memory, and the like.
The storage 400 stores OS02 and a failure information processing program 03 that is an application program that runs on the OS02. Examples of the storage 400 include an HDD (Hard Disk Drive), an SSD (Solid State Drive), a magnetic disk, a magneto-optical disk, a CD-ROM (Compact Disc Read Only Memory), and a DVD-ROM (Digital Versatile Disc Read Only Memory). And semiconductor memory. The storage 400 may be an internal medium directly connected to the bus of the computer 1 or an external medium connected to the computer 1 via the interface 500 or a communication line.
The main memory 200, the non-volatile memory 300, and the storage 400 are examples of storage devices.

Further, the CPU 100 secures the first storage area M1 and the second storage area M2 in the main memory 200 in accordance with the BIOS01.
The first storage area M1 is an area for storing first log data, which is log data generated by the BIOS 01, a failure detection date and time, and an analyzed flag. The analyzed flag is a bit indicating whether or not the analysis of the associated first log data has been completed, and indicates 0 when not analyzed and indicates 1 when analyzed.
The second storage area M2 is an area for storing second log data, which is log data generated by the failure information processing program 03, a failure detection date and time, and a reported flag. The reported flag is a bit indicating whether or not reporting to the BMC of the associated second log data has been completed, and indicates 0 when not reported and indicates 1 when reported. .
Both the first storage area M1 and the second storage area M2 are referred to by both the BIOS 01 and the failure information processing program 03. Therefore, the CPU 100 secures areas of a predetermined size as the first storage area M1 and the second storage area M2 at a predetermined address of a memory block (fixed memory) whose address does not change in the main memory 200. To do.

FIG. 2 is a schematic block diagram illustrating a software configuration of the computer according to the first embodiment.
The CPU 100 functions as the log collection unit 101, the first log recording unit 102, the second log acquisition unit 103, and the transmission unit 104 by executing the BIOS 01.

  The log collection unit 101 reads a register holding information that can identify the failure location of the hardware that has detected the failure, and generates first log data based on the read information.

  The first log recording unit 102 records the first log data generated by the log collection unit 101 in the first storage area M1 in association with the analyzed flag. The first log recording unit 102 sets the analyzed flag to 0 when recording the first log data.

  The second log acquisition unit 103 acquires information stored in the second storage area M2. Since the second storage area M2 is secured in the memory block of the fixed memory, the second log acquisition unit 103 refers to the second storage area M2, and stores the second log data generated by the failure information processing program 03. Can be acquired. The second log acquisition unit 103 acquires the second log data associated with the analyzed flag indicating 0.

  The transmission unit 104 transmits the second log data acquired by the second log acquisition unit 103 to the BMC. The transmission unit 104 sets 1 in association with the second log data for which transmission has been completed among the reported flags stored in the second storage area M2.

  The CPU 100 functions as a first log acquisition unit 105, an analysis unit 106, a reduction unit 107, and a second log recording unit 108 by executing the failure information processing program 03.

  The first log acquisition unit 105 acquires information stored in the first storage area M1. Since the first storage area M1 is secured in the memory block of the fixed memory, the first log acquisition unit 105 can acquire the first log data generated by the BIOS 01 by referring to the first storage area M1. it can. The first log acquisition unit 105 acquires first log data associated with an analyzed flag indicating 0.

  The analysis unit 106 performs analysis of the acquired first log data. That is, the CPU 100 performs a temporary analysis on the OS 02 before the analysis by the BMC. The analysis unit 106 sets 1 in the analyzed flag recorded in the first storage area M1 and associated with the first log data that has been analyzed.

  The reduction unit 107 generates second log data having a data amount smaller than that of the first log data based on the analysis result by the analysis unit 106. For example, the reduction unit 107 reduces the data amount by deleting an event log having a small relationship with the failure from the first log data. Since the reduction unit 107 generates the second log data after the analysis by the analysis unit 106 is completed, the analyzed flag is information indicating whether or not the second log data has been created based on the first log data. It can be said that.

  The second log recording unit 108 records the second log data in the second storage area M2 in association with the reported flag. The second log recording unit 108 sets the reported flag to 0 when recording the second log data.

FIG. 3 is a flowchart showing log collection processing by the computer according to the first embodiment.
When a failure occurs in the computer 1 and the hardware that detects the failure issues an interrupt request to the CPU 100, log collection processing is started. First, the CPU 100 transfers the control right from the OS 02 to the BIOS 01 by handover (step S001). By executing the BIOS 01, the log collection unit 101 of the CPU 100 reads information from a register that holds information that can identify a hardware failure location, and generates first log data based on the read information (step S002).

  Next, the first log recording unit 102 determines whether or not there is a free space in the first storage area M1 (step S003). If there is no free space in the first storage area M1 (step S003: NO), the oldest first log data stored in the first storage area M1 is deleted (step S004). When the first storage area M1 is empty (step S003: YES) or when the first log data is deleted from the first storage area M1, the first log recording unit 102 generates the first log generated in step S002. Data is recorded in the first storage area M1 (step S005). At this time, the first log recording unit 102 sets the analyzed flag associated with the first log data to 0. The first log recording unit 102 records the first log data at the end of the free area of the first storage area M1.

  Next, the first log recording unit 102 transfers the control right from the BIOS 01 to the OS 02 by handover (step S006), and ends the log collection processing. As a result, in the computer 1, the OS 02 acquires the control right before sending the log data to the BMC.

FIG. 4 is a flowchart showing failure notification processing by the computer according to the first embodiment.
The CPU 100 executes the failure information processing program 03 at a timing related to a predetermined cycle, and starts failure notification processing. First, the first log acquisition unit 105 refers to the information stored in the first storage area M1, and determines whether there is an analyzed flag indicating 0 (step S101). If there is no analyzed flag indicating 0 (step S101: NO), the computer 1 ends the failure notification process.

  On the other hand, when there is an analyzed flag indicating 0 (step S101: YES), the first log acquisition unit 105 acquires first log data associated with the analyzed flag indicating 0 (step S102). Next, the analysis unit 106 analyzes the acquired first log data (step S103). The reduction unit 107 generates second log data in which the data amount of the first log data is reduced based on the analysis result by the analysis unit 106 (step S104). The analysis unit 106 sets the value of the analyzed flag associated with the first log data to be analyzed to 1 (step S105).

  Next, the second log recording unit 108 determines whether or not there is a free space in the second storage area M2 (step S106). If there is no free space in the second storage area M2 (step S106: NO), the oldest second log data stored in the second storage area M2 is deleted (step S107). When the second storage area M2 is empty (step S106: YES), or when the second log data is deleted from the second storage area M2, the second log recording unit 108 generates the second log generated in step S104. Data is recorded in the second storage area M2 (step S108). At this time, the second log recording unit 108 sets the reported flag associated with the second log data to 0. The second log recording unit 108 records the second log data at the end of the free area of the second storage area M2.

  Next, the CPU 100 transfers the control right from the OS 02 to the BIOS 01 by handover (step S109). By executing the BIOS 01, the transmission unit 104 refers to the information stored in the second storage area M2, and determines whether there is a reported flag indicating 0 (step S110). If there is no reported flag indicating 0 (step S110: NO), the CPU 100 transfers the control right from the BIOS 01 to the OS 02 by the handover (step S111), and ends the failure notification process.

  On the other hand, when there is a reported flag indicating 0 (step S110: YES), the second log acquisition unit 103 acquires second log data associated with the analyzed flag indicating 0 (step S112). Next, the transmission unit 104 transmits the second log data acquired to the BMC (Step S113). Since the second log data has a smaller data amount than the first log data, the transmission time of the second log data is shorter than the transmission time of the first log data. When the transmission unit 104 completes the transmission of the second log data, the transmission unit 104 sets the value of the reported flag associated with the second log data to 1 (step S114). Then, the CPU 100 transfers the control right from the BIOS 01 to the OS 02 by the handover (step S111), and ends the failure notification process.

  As described above, according to the first embodiment, when a failure occurs in the computer 1, the CPU 100 reduces the data amount of the first log data by executing the failure information processing program 03 and outputs the second log data. Generate. The inventor has obtained the knowledge that much of the processing time is spent on transmitting log data in failure processing in a general computer. That is, according to the computer 1 according to the first embodiment, it can be understood that the time for which the BIOS 01 occupies the control right is shortened by reducing the amount of log data to be transmitted to the BMC.

  According to the first embodiment, the computer 1 analyzes the first log data by executing the failure information processing program 03, and generates the second log data based on the first log data. That is, the computer 1 performs a primary analysis of the first log data and causes the BMC to analyze the second log data that is the analysis result. Thereby, the computer 1 can shorten the time for which the BIOS 01 occupies the control right while ensuring the analysis accuracy of the log data.

As described above, the embodiment has been described in detail with reference to the drawings. However, the specific configuration is not limited to that described above, and various design changes and the like can be made.
The computer 1 according to the first embodiment functions as the first log acquisition unit 105, the analysis unit 106, the reduction unit 107, and the second log recording unit 108 by the failure information processing program 03 that runs on the OS02. Not limited to. For example, in another embodiment, the BIOS 01 may include a program for realizing at least some of these functions. In this case, the handover to the OS02 is not performed after the first log data is generated, but the amount of data to be transmitted is reduced, so that the performance degradation of the OS02 is prevented compared to the case where the first log data is transmitted by the BIOS01. be able to. For example, in another embodiment, the OS 02 may include a program for realizing at least some of these functions.

  Moreover, although the computer 1 which concerns on 1st Embodiment transmits 2nd log data to BMC by BIOS01, it is not restricted to this. For example, the computer 1 according to another embodiment may transmit the second log data by the failure information processing program 03 or the OS02.

  The fault information processing program 03 according to the first embodiment causes the computer 1 to analyze the first log data, but is not limited thereto. For example, the failure information processing program 03 according to another embodiment may reduce the amount of data without analysis by causing the computer 1 to thin out the first log data.

  In the first embodiment, the first storage area M1 and the second storage area M2 are secured on the main memory 200. However, the present invention is not limited to this. For example, in another embodiment, the first storage area M1 and the second storage area M2 may be secured on the nonvolatile memory 300. In this case, even if the service of the computer 1 is stopped due to shutdown or the like, the log data can be retained.

  Moreover, although the computer 1 which concerns on 1st Embodiment transmits log data to BMC, it is not restricted to this. For example, the computer 1 according to another embodiment may transmit failure information other than log data (for example, failure analysis result) to the BMC. In this case, the computer 1 generates second failure information in which the data amount of the failure information (first failure information) is reduced.
