Description

Description Status monitoring method, network system, and recording medium

The present invention relates to a state monitoring method, a network system, and a recording medium, and more particularly, to a state monitoring method, a network system, and a recording medium that monitor states of a plurality of information processing units connected to a network.

In recent years, as network systems such as LANs (Lacal Area Networks) have become large-scale, it has become important to manage the state of each computer connected to the network.

For example, if a failure occurs in the file device or memory of a computer connected to the network, using the computer as it is will cause problems such as the inability to save the transmitted information. If the user immediately recognizes such a condition and repairs the fault, there is no problem, but if the user cannot recognize such a condition of the computer, the computer remains connected to the network with the fault. And trouble occurs. For this reason, it was necessary to manage the status of the convenience store connected to the network, and to be able to take appropriate measures according to the status. Background art

FIG. 11 shows a block diagram of an example of a conventional network system.

The conventional network system 100 is connected to the network 101 and provides a server 102 that provides information, and a client that is connected to the network 101 and accesses the server 102 and receives information provided. It consists of 103.

The server 102 acquires status information from the client 103 and manages it. Also

The client 103 notifies the server 102 of status information.

In the conventional monitoring method, the server 102 simply stores the state of the client 103. As such a monitoring method, for example, Japanese Patent Application Laid-Open No. Sho 63-18

Proposed by No. 0 144 Also, in this monitoring method, if the failure is not recognized by the client 103, the damage of the chapter P occurs until the administrator of the server 102 notifies the user of the client 103 of the failure. The user of the client 103 cannot perform necessary measures, and a trouble has already occurred if the administrator notifies the user of the failure late.

Therefore, Japanese Patent Application Laid-Open Nos. 6-26635 and 3-104446 have already been proposed in order to promptly notify a failure.

For example, in the network resource monitoring method disclosed in JP-A-6-26635, when a failure occurs in a monitored device, when the monitored device notifies the monitoring device of the occurrence of the failure, the monitoring device registers in advance. Notify another monitored device that a failure has occurred.

In this way, a predetermined administrator is notified of the failure, and the administrator can reliably recognize the failure of the monitored device.

However, in the conventional method of monitoring the status of a network system, the server simply collects the status information of the client, and the server administrator recognizes the status information collected from the client, and the client in which the failure has occurred. It is necessary to notify the user of the service, and there is a problem that it is left as it is while it is out of order, which may hinder the network.

In the fault information monitoring methods disclosed in JP-A-6-63635 and JP-A-3-104446, when a failure occurs in a monitored device, the monitored device simply switches from the monitored device to the monitoring device. When the occurrence of the failure is notified, the monitoring device notifies the other registered monitored device of the occurrence of the failure, so that not only the user of the monitored device but also the monitored device in which the failure has occurred can be monitored. It only notifies the administrator of the problem.If it takes time for the user and the administrator to recognize the notification and take measures to deal with the problem, the system will be left with a failure and cause problems to the network. was there.

The present invention has been made in view of the above points, and it is possible to prevent a network trouble due to a failure of an information processing unit by analyzing a state of the information processing unit on a network and performing a measure according to the state. It is an object to provide a state monitoring method, a network system, and a recording medium. Disclosure of the invention

The present invention monitors the states of a plurality of information processing means connected to a network, acquires the states of the plurality of information processing means, and determines the importance of the state of each information processing means according to the acquired state. It analyzes and notifies each information processing means of the analyzed importance, and causes each information processing means to execute a process according to the notified importance.

According to the present invention, by causing each information processing means to execute processing according to the importance notified by the notification procedure, the user of the information processing means notified of the importance automatically performs the processing without performing the processing. Therefore, it is possible to prevent trouble on the network due to a failure of each information processing means.

In addition, the management means for managing the information processing means is notified of the importance analyzed in the state analysis procedure.

According to the present invention, by notifying the management means of the importance analyzed in the state analysis procedure, the state of the information processing means can be managed collectively in a case where a plurality of information processing means are provided.

Furthermore, when the importance is significant, the processing of the information processing means is stopped. According to the present invention, when the degree of importance reaches a predetermined level and the state becomes serious, the processing of the information processing means is stopped, so that the information processing means is not used with a serious failure, Troubles on the network due to failure of the processing means can be prevented.

In addition, status acquisition, status analysis, and notification should be performed periodically.

According to the present invention, by periodically acquiring the state, analyzing the state, and notifying the information, the state of the information processing means can be periodically recognized, and a measure can be taken in accordance with the state. Network problems due to failure of information processing means can be reliably prevented.

Further, a plurality of information processing means are connected to the network.

According to the present invention, by connecting a plurality of information processing means to a network, it is possible to reliably prevent a plurality of information processing means from having a network trouble due to a failure of the information processing means on the network.

Here, the operation of the server 3 will be described with reference to the drawings.

FIG. 3 shows a processing flowchart of the server of one embodiment of the present invention.

The server 3 issues a status acquisition request for acquiring status information of the client 4 to the client 4 at regular intervals (steps S1 and S1-2). When status information is notified from the client 4 in response to the status acquisition request (step S1-3), the status information obtained from the client 4 is analyzed (step S1-4).

The status information from the client 4 is composed of an event code. The event code notified from the client 4 is issued according to the operation in the client 4.

The event code consists of the codes "1" to "6".

The event code “1” indicates that one retry processing occurred in the write processing to the hard disk in client 4.

The write processing to the hard disk is processed by the hard disk driver, and the occurrence of the retry processing is recognized by the hard disk driver. The hard disk driver generates event code "1" every time a retry process occurs. The event code "1" generated by the hard disk driver is stored as status information in the client 4.

Event code “2” indicates that one retry occurred in the read processing to the hard disk in client 4.

The read processing to the hard disk is performed by the hard disk driver, and the occurrence of the retry processing is recognized by the hard disk driver. The hard disk driver generates event code "2" every time a retry process occurs. The event code “2” generated by the hard disk driver is stored in the client 4 as status information.

Event code "3" indicates that one retry occurred in the write processing to the floppy disk in client 4.

The floppy disk driver generates event code "4" each time a retry process occurs. The event code "4" generated by the floppy disk driver is held in the client 4 as status information.

Event code "5" indicates that one parity error occurred in memory at client 4.

A memory parity error is detected by hardware such as a memory controller and reported to the CPU. In hardware such as a memory controller, an event code “5” is reported to the CPU every time a notify error occurs. The CPU holds the notified event code “5” in the client 4 as state information.

Event code “6” indicates that one communication error occurred when connecting client 4 to network 2.

The communication error is detected by hardware such as a communication control unit, and is notified to the CPU. The hardware such as the communication control unit notifies the CPU of the event code "6" every time a communication error occurs. The CPU holds the notified event code “6” in the client 4 as state information.

If the same event code occurs, the frequency is counted.

As described above, the event codes “1” to “6” are held in the client 4 every time an event occurs, and are notified to the server 3 together with the frequency in response to a status communication request from the server 3.

In step S1-4, the server 3 determines the importance of the failure according to the event codes "1" to "6" and the frequency as shown in FIG. At this time, an importance determination table 26 is set in the file device 19 of the server 3, and the server 3 refers to the importance determination table 26 to determine the importance of the failure. Determine the degree. FIG. 5 shows a data configuration diagram of the importance determination table according to one embodiment of the present invention.

For example, as shown in FIG. 5, if the event code is “1” and the frequency is “1” as shown in FIG. 5, the importance determination table 26 indicates that the importance is “4”, the event code is “1”, and the frequency is “1”. If it is "2" times, the importance is "1", and the event code is "1". If the frequency is "3" or more, the importance is "0".

At this time, the importance is set so that the smaller the value, the greater the importance. FIG. 6 is a diagram for explaining the importance of one embodiment of the present invention.

The importance is divided into five levels from "0" to "4".

A severity of "0" means the most serious, indicating that it is necessary to immediately "power off and prohibit use of the machine" as shown in Figure 6. o

In addition, the importance level “1” means that the importance level is next to the importance level “0”, and as shown in FIG. 6, “A warning message is displayed and access to the corresponding device is prohibited. It indicates that it is necessary.

Further, the importance “2” means that the importance is next to the importance “1”, and as shown in FIG. 6, “displays a warning message and then prompts the user to power off.” Means.

In addition, the importance level “3” means that the importance level is next to the importance level “2”, and as shown in FIG. 6, “After the warning message is displayed, the use of the network is prohibited.” Means.

The importance “4” means that the importance is the least important, and simply means “display a warning message” as shown in FIG.

The server 3 determines the above-mentioned importance levels “0” to “4” from the event code from the client 4 and its frequency. At this time, if there is no event code in the status information notified to the server 3 from the client 4, the server 3 determines that the client 4 has no abnormality.

Here, returning to FIG. 3, the description will be continued.

If any of the above-mentioned priorities is determined in step S 1-4 (step S 1-5), the client 4 that has notified the determined importance of the status information, and Then, it notifies the management device 5 (step S1-6).

The server 3 repeats the processing of steps S1-1 to S1-6 at regular intervals, and executes normal processing during the processing of steps S1-1 to S1-6 (step S1). 1-8). Steps S1-1-1 to S1-6 and S1-8 are repeatedly executed until the processing is stopped, for example, when the power of the server 3 is turned off (Step S17)

Next, the configuration of the client 4 will be described with reference to the drawings.

When the client 4 is notified of the status acquisition request from the server 3 (step S2-1), the client 4 sends the event code stored in the status storage area 40 and its frequency to the server 3 as status information. (Step S2-2).

As a result of transmitting the status information to the server 3 in step S2-2 and receiving a message, that is, an analysis result (importance) from the server 3, the processing corresponding to the received importance is executed (step S2-2). twenty four ) .

For example, when the server 3 notifies the importance level “0”, the power is immediately turned off as shown in FIG. 6, and the use of the device is prohibited. When the importance “1” is notified from the server 3, a warning message is displayed on the display 37 and access to the device is prohibited.

Furthermore, when the server 3 notifies the server of the importance “2”, a warning message prompting power off is displayed. When the server 3 notifies the importance level “3”, a warning message is displayed and access to the network 2 by the communication control unit 27 is prohibited.

When the server 3 notifies the server of the importance "4", a warning message is displayed.

In addition, since the normal processing is hindered for the importance levels "0" to "2", the processing itself on the client 4 is stopped, and normal processing is possible for the importance levels "3" and "4". When the server 3 notifies the server of the importance "3" or "4", the normal processing is executed (steps S2-5, S2-7).

The processes of steps S2-1 to S2-5 and S217 are repeatedly executed until the power of the client 4 is turned off and the process is stopped (step S2-6).

In the normal processing of step S2-7, when an event code "1" is generated in the hard disk driver, the CPU 28 detects this, and the event code "1" of the state information storage area 40 is detected. The frequency of “11”. When the event code “2” occurs in the hard disk drive, the CPU 28 detects this and sets the frequency of the event code “2” in the state information storage area 40 to “11”.

When the event code “3” occurs in the floppy disk driver, the CPU 28 detects this and sets the frequency of the event code “3” in the status information storage area 40 to “10”. 1 "Yes. When the event code "4" is generated in the floppy disk driver, the CPU 28 detects this and sets the frequency of the event code "4" in the state information storage area 40 to "+1".

When an event code “5” occurs in the memory controller that controls the RAM 29, the CPU 28 detects the event code and changes the frequency of the event code “5” in the state information storage area 40 to “+1”. I do. When the event code “6” is generated in the communication control unit 27, the CPU 28 detects this and sets the frequency of the event code “6” in the state information storage area 40 to “11”.

As described above, the event code generated in the normal process and the frequency of the event code until the status information request is notified from the server 3 are accumulated in the status information storage area 40.

As described above, in the case of a serious failure or the like, the use of the client 4 is automatically prohibited according to the result of the state analysis from the server 3, that is, the importance. Therefore, even if the user of the client 4 cannot recognize the failure, it is possible to suppress the occurrence of a serious trouble in the network 2.
