DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to an information processing system constituted by a plurality of processors. The present invention relates to collecting fault information when a fault occurs in an information processing system.

〔overview〕

The present invention is an information processing system in which a plurality of processors are interconnected via a communication line, in which each processor checks communication data sent and received between each other,
When a failure is detected in one of the processors, by sending a request to collect failure information to that processor, even if the failure is not detected in the own processor, the failure can be detected and the failure information can be collected. This eliminates delays in collection, prevents the disappearance of information related to the cause of failures, and saves the manpower required to collect information.

[Conventional technology]

Conventionally, in this type of fault information collection, faults were detected only by fault detection means in a processor where a fault occurred, and fault information was collected based on instructions from the fault detection means.

Furthermore, when another processor detects a fault in its own processor, the operator collects the fault information.

[Problem to be solved by the invention]

In the conventional failure information collection described above, failure information discovered in other processors due to disturbances or omissions in data sequences sent to other processors is not automatically collected.
When this is done manually, information regarding the root cause of the failure is lost due to timing delays, which has the drawback of hindering analysis of the cause of the failure.

The present invention eliminates these drawbacks, and provides a system that can detect even faults discovered in other processors, eliminate delays in collecting fault information, and prevent information about the cause of faults from disappearing. The purpose is to provide

The present invention is characterized by comprising a collection activation means.

A second aspect of the present invention is that a plurality of processors are connected to each other via a communication line, and each of the processors has a communication means for communicating with each other, and detects a failure occurring within its own processor and collects failure information. In an information processing system, each of the processors has another processor failure detection means for detecting a failure in another processor, and another processor failure detection means that detects a failure in another processor when the other processor failure detection means detects a failure in another processor. , a fault information collection requesting means for sending a startup request to the fault information collection means of another processor in which a fault has occurred; and receiving a fault information collection startup request from the fault information collection requesting means, and starting the fault information collection means. The present invention is characterized by comprising a failure information collection activation means.

Preferably, the fault information collecting means includes means for collecting fault information when receiving a startup request from the fault information collection starting means.

[Effect]

Communication data is checked between processors, and when a fault in another processor is detected, a request to collect fault information is sent to the processor where the fault was detected, and the processor that receives this request collects the fault information. conduct.

As a result, it is possible to know that a failure has occurred even if the failure is not detected in the own processor, eliminating delays in collecting failure information, preventing information related to the root cause from disappearing, and reducing the need for human resources to collect information. It can be omitted.
