Abstract

PROBLEM TO BE SOLVED: To perform efficient patrol diagnosis by utilizing monitoring information at the time of normal access and changing dynamically the cycle of a patrol diagnosis according to a normal access ratio. SOLUTION: Monitoring information that is recorded by a monitoring function is read (step 10). A normal access ratio α is calculated by counting the number of accesses to a component that is an object within a fixed time and the number of normal accesses among them based on the monitoring information. The calculated ratio αis compared with a defined value β that is previously defined (step 11). When the ratio α is <= the value β, the cycle of a patrol diagnosis of the component is shortened (step 13). On the contrary, when the ratio αexceeds the value β, the cycle of a patrol diagnosis of the component is made long (step 12).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a computer and the like.
Regarding the preventive maintenance / failure diagnosis method of various components such as an arithmetic processing unit, a main storage unit, a peripheral / communication control unit, and a terminal of an information communication processing device, the access state of a target component to be diagnosed is determined. The present invention relates to a patrol diagnosis method that checks to make diagnosis more efficient.

[0002]

2. Description of the Related Art In a conventional patrol diagnosis system for maintenance / failure diagnosis of components of a computer system, all or some of the components of the computer system are periodically performed at predetermined time intervals. Then, a patrol diagnosis is performed, and based on the diagnosis result, it is determined whether the system component is normal or abnormal (failure).

[0003]

However, the above-described conventional patrol diagnosis method has the following problems.

[0004] The problem is that in the conventional method, patrol diagnosis is performed at regular time intervals irrespective of the state of normal access until immediately before, and as a result, useless diagnosis is performed. It is that.

The reason is as follows. That is, if the normal access up to immediately before is normally performed, then
Even if a patrol diagnosis is performed, the probability of normality is high. For components that have been accessed normally until just before,
It is wasteful to perform the diagnosis just because it is time to perform the regular patrol diagnosis, and this patrol diagnosis consumes resources such as an arithmetic processing unit and a main storage unit of the computer system ( That is, the overhead of the system is increased), and the system performance is reduced.

Accordingly, the present invention has been made in view of the above problems, and an object thereof is to dynamically change the period of patrol diagnosis by using monitoring information at the time of normal access. Accordingly, an object of the present invention is to provide a patrol diagnosis method that enables efficient patrol diagnosis and reduces system overhead.

[0007]

In order to achieve the above-mentioned object, a patrol diagnosis system of the present invention provides a patrol diagnosis system that, whenever an access to each system component of a computer system occurs, the time of the access and whether the access result is normal or abnormal. Monitoring means for recording whether or not, and patrol diagnosis means for each of the system components, comprising, at regular intervals, analyzing the monitoring information collected by the monitoring means, the number of accesses within a given time, Calculate the ratio with the number of times the access result was normal as a normal access ratio, and when the normal access ratio exceeds a predetermined value, increase the period of subsequent patrol diagnosis, If the normal access ratio is equal to or less than a predetermined value, the period of the subsequent patrol diagnosis is shortened. Wherein, further comprising means for controlling to.

[Summary of the Invention] In order to perform an efficient patrol diagnosis, it is desirable to perform a diagnosis with a high ratio of abnormalities in normal access until immediately before. In other words, for those who are performing normal access, increasing the period of the patrol diagnosis and reducing the number of patrol diagnoses will reduce the overhead of the entire system.

The present invention has been made based on the above findings, and adjusts a cycle (time interval) of performing patrol diagnosis for a component of a computer system based on a normal access state immediately before. By doing so, it is possible to omit stochastic useless patrol diagnosis. Thereby, the overhead of patrol diagnosis given to the system can be reduced.

As a result, it is possible to speed up the entire computer system and perform efficient maintenance.

[0011]

Embodiments of the present invention will be described below. In a preferred embodiment of the patrol diagnosis method of the present invention, a diagnosis means for the various components in the computer system (3 in FIG. 1) and a monitoring means for recording and leaving a normal access result to the various components (FIG. 1) 1) and 4). Specific monitoring information includes, for each normal access, time information and an access result status indicating whether the access ended normally or abnormally.

In the embodiment of the present invention, the monitoring information in which the access results of the component parts are recorded is analyzed at regular intervals, and the ratio of the normal access count to the access count within the fixed time is calculated. If the ratio exceeds a predetermined value, the period for executing the patrol diagnosis is lengthened, and otherwise, the period for executing the patrol diagnosis is shortened, thereby reducing the overhead of the patrol diagnosis itself. And efficient diagnosis can be performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. Referring to FIG. 1, in one embodiment of the present invention, a patrol diagnosis function 3
And the monitoring function 4 are executed. When the patrol diagnosis function 3 and the monitoring function 4 are realized by software control, the programs are developed in the main storage unit 2 and executed by the arithmetic processing device 1 including the CPU.

The monitoring function 4 includes time information of normal access to the peripheral control unit 5, the peripheral device 6, the communication control unit 7, the communication terminal 8 and the like, which are components of the computer system to be executed by the patrol diagnosis function 3, The result of the access, that is, information (status information) indicating normal or abnormal is recorded. The components to be patrol-diagnosed may include the arithmetic processing unit 1 and the main storage unit 2 in some cases.

The patrol diagnosis function 3 diagnoses a component to be diagnosed at a certain time interval. The present embodiment is characterized in that the execution cycle of the patrol diagnosis is automatically and dynamically varied.

FIG. 2 is a flowchart for explaining the operation of one embodiment of the present invention. The operation of one embodiment of the present invention will be described with reference to FIGS.

First, the monitoring information recorded by the monitoring function 4 is read (step 10). In this monitoring information, time information at the time of access for each component and result information indicating whether the access ended normally or abnormally are recorded. Based on this monitoring information, the number of accesses to the target component within a certain period of time and the number of times of normal access among them are counted, and the normal access ratio α is calculated. Then, the obtained normal access ratio α is compared with a specified value β specified in advance (step 11).

By this comparison processing, the normal access ratio α
Is less than or equal to the specified value β, the period of the patrol diagnosis for the component is shortened (step 13).

That is, a component having a low normal access ratio is a component having a high frequency of failure or failure.
For the components, it is necessary to check the problem part in detail by performing a detailed patrol diagnosis.

Conversely, if the normal access ratio α exceeds the specified value β, the period of the patrol diagnosis for the component concerned is lengthened (step 12). This is because it is a component having no problem and the number of patrol diagnoses may be small.

[0022]

As described above, according to the present invention,
By using the monitoring information at the time of normal access and dynamically changing the period of the patrol diagnosis according to the normal access ratio, there is an effect that an efficient patrol diagnosis can be performed.

The reason is as follows. If the component to be patrol diagnosed has been normally accessed up to immediately before, the probability of continuing normal operation after that is high, and the number of patrol diagnoses may be small. This is because if the component is a component, it is necessary to perform a detailed patrol diagnosis and check the location of the problem.
