Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a maintenance diagnosis device that collects log information, and particularly relates to a maintenance diagnosis device that collects log information and data of the maintenance diagnosis device.

[Conventional technology]

Conventionally, when a fault is detected by a check circuit installed in the nodeware of a central processing unit, the occurrence of the fault is reported to the service processor (SVP), which controls maintenance diagnosis, and the SVP collects internal information of the faulty central processing unit. (The collected information is called failure log information).

[Problem that the invention seeks to solve]

The above-mentioned conventional maintenance diagnostic equipment collects failure log information from the central processing unit, which is useful for failure analysis, but the information on the SVP side is not fully collected.
The drawback is that it takes a significant amount of time to recreate the SVP environment related to the central processing unit failure, requires a lot of evaluation time on the system that includes the central processing unit, and also requires a large amount of time to evaluate the system including the central processing unit. However, since this is after the central processing unit has logged, the internal state of the SVP changes and there is a drawback that valid data cannot be obtained.

[Means for solving problems]

The maintenance diagnostic device of the present invention is connected to a central processing unit through a diagnostic interface, and includes a log collection means for collecting the internal state of the central processing unit as log information when the central processing unit fails through the diagnostic interface. a calculation stage consisting of a diagnostic device; a maintenance diagnostic device data collection means for collecting the internal state of the maintenance diagnostic device, which is separate from the log collecting means of the maintenance diagnostic device; a central processing unit failure log collection means for collecting the internal state of the central processing unit as log information; a data file storage means for storing the contents collected by the maintenance diagnosis device data collection means; and log file storage means for storing contents collected by the central processing unit failure log collection means.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a configuration diagram showing one embodiment of the maintenance diagnosis device of the present invention, and Fig. 2 is! 1 is a flowchart showing the configuration of the central processing unit R harm detection means 10 in FIG. 1, FIG. 3 is a flowchart showing the configuration of the maintenance diagnosis device data collection means in FIG. 2 is a flowchart showing the configuration of a processing device failure log collection means 21. FIG.

As shown in FIG. 1, this embodiment includes a central processing unit 1 including a central processing unit failure detection means 10, connected to the central processing unit 1 through a diagnostic interface, and a maintenance diagnostic device data collection means and the central processing unit. fault input means 3; storage means 4 comprising a data file 40 and a log file 41 and connected to the maintenance processor 2 by an interface 8;
It consists of an output means 5 connected to the maintenance processor 2 through an interface 9.

As shown in FIG. 2, the central processing unit failure detection means 10 is composed of a failure detection judgment power and a maintenance/diagnosis device data collection means activation 51.

As shown in FIG. 3, the maintenance diagnostic device data collection means includes a maintenance processor register collection start ω, a maintenance processor register collection 61, a maintenance processor memory collection start 62, a maintenance processor memory collection 63, and a storage means data file. It consists of output 6 and central processing unit log collection means activation ω.

The central processing unit failure log collection means 5 is shown in FIG.
It consists of a central processing unit log collection activation 70, a central processing unit log collection 71, and a storage means log file output cuff 2.

Next, the operation of this embodiment will be explained with reference to the drawings.

When a failure occurs in the central processing wave [1, the central processing unit failure detection means 10 detects the failure, and the presence or absence of a failure is determined by the failure detection judgment 50 of the central processing unit failure detection means 10. If the judgment result of the fault detection judgment power is faulty heat, no action is taken and the processing of the central processing unit fault detection means 10 is finished, but if there is a fault, the maintenance diagnosis device data collection means is activated 5.
Execute 1. The maintenance/diagnosis device data collection means activation 51 activates the maintenance/diagnosis device data collection means in the memory that is not used by the software of the normal maintenance processor 2. When the maintenance/diagnosis device data collection means is activated, maintenance processor register collection activation ω is performed, and maintenance processor register collection 61 is executed. The maintenance processor register collection 61 collects the contents of the software registers of the maintenance processor 2. Next, maintenance processor memory collection startup 62 is performed, and maintenance processor memory collection 8 is executed. The maintenance processor memory collection 63 collects the contents of memory used by software. Next, the data collected by the maintenance processor register collection 61 and the maintenance processor memory collection 63 are inked into the data file 40 of the storage means 4 by the storage means data file output 64 created by normal software. Output through Ace 8. When the output is completed, a central processing unit log collection means activation 65 activates the central processing unit log collection means 4 made of ordinary software. A log collection 71 by the central processing unit log collection means 4 collects internal information of the hardware of the central processing unit 1 as log information through the diagnostic interface 6. Next, the storage means log file output cuff 2 outputs the data collected by the central processing unit log collection 71 to the log file 41 of the storage means 40 through the interface 8.

The data file 40 and log file 41 stored in the storage means 4 as described above are read out through the interface 8 by a normal means specified by the input means 3 connected to the maintenance processor 2 through the interface 7, and then read out through the interface 8. 9 to be displayed on the output means 5.

〔Effect of the invention〕

As explained above, the present invention provides a data collection means for collecting the internal state of the maintenance processor independent of the log collection means for collecting logs of the central processing unit in the event of a failure in the maintenance diagnostic device. By executing the log collection means of the central processing unit after execution, the log of the central processing unit can be collected at the same time as the data of the maintenance processor, and the effect is that information that can easily reproduce the environmental state at the time of failure can be provided. There is.
