DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network monitoring apparatus, and more particularly, to a terminal based on message information obtained from communication management of a general-purpose computer in a centralized network composed of a general-purpose computer and many terminals connected thereto. The present invention relates to a network monitoring device that monitors the status of a network.

[0002]

2. Description of the Related Art In a centralized network in which many terminals are connected to a general-purpose computer,
With the increase in the scale, that is, the increase in the number of terminals connected to the general-purpose computer, the number of faulty terminals also tends to increase. When a failure occurs in a terminal, it is important to recognize the failure as soon as possible, and to quickly take measures to recover from the failure.

Generally, in a centralized network,
All terminals are collectively managed by a communication management provided in an OS (operating system) of a general-purpose computer. When a failure occurs in a terminal at the start of communication or during communication, information on a state change from the communication management to the OS is provided. Is notified. The notification from the communication management to the OS includes the name of the terminal in which the failure has occurred, a failure code indicating the cause of the failure, and the like.
In addition, various information useful for failure analysis is included. When the OS receives the failure notification from the communication management, the OS converts the failure notification into a message and outputs the message to the console terminal and the message history file. Therefore, by looking at the screen of the console terminal, the operator can recognize whether or not a failure has occurred in the terminal. It is also possible to determine the cause of a failure or the like from the content of the displayed message or the content stored in the message history file.

[0004]

However, the console terminal displays all messages to be notified to the operator, such as messages relating to peripheral devices such as an external storage device connected to the general-purpose computer, and a large number of messages. Is displayed at once, scrolling deletes old messages from the screen. For this reason, the operator is likely to overlook the fault message of the terminal. When some kind of business is performed in a centralized network, the main concern of the operator is whether the terminal is normal or not. Therefore, a method that can more reliably monitor the state of the terminal is desired.

An object of the present invention is to enable an operator to more reliably recognize a change in the state of a terminal.

As a technique for monitoring the state of the network, for example, as disclosed in Japanese Patent Application Laid-Open No. 6-350602, a network management device is connected to each network component via an information line, and all network components are monitored. There is a technology in which status monitoring is controlled by a network management device. However, this method is suitable for a distributed network. However, in the case of a centralized network to which the present invention is applied, a function such as a failure notification function is required on each network component device, and a general-purpose network is required. In addition to the line connecting the computer and each terminal, a new information line connecting the network management device and each terminal is required,
Extensive retrofitting of existing centralized network configurations is required. It is also conceivable to realize the function of the network management device as one process of a general-purpose computer. However, doing so significantly increases the load on the general-purpose computer, and causes a reduction in the original processing.

[0007] It is another object of the present invention to monitor the status of a terminal without significantly increasing the load on a general-purpose computer.

[0008]

According to the present invention, there is provided a network monitoring apparatus for a centralized network comprising a general-purpose computer and a plurality of terminals connected to the general-purpose computer through a communication path.

Next, an example of the above embodiment of the present invention will be described.

FIG. 2 is a functional block diagram of an example according to the first embodiment of the present invention. The centralized network in this example includes a general-purpose computer 200 and a plurality of terminals 20 connected to the general-purpose computer 200 through communication paths 203-1 to 203-n such as a dedicated line, a packet network, and a public line.
1 to 201-n, and a plurality of terminals 202-1 to 202-n connected to the general-purpose computer 200 via the communication path 204 and the LAN line 205.

The general-purpose computer 200 has a communication management 2
In addition, an OS 206 having an OS 07 and a failure monitoring process 208 are mounted, and a console terminal 209 and a message history file 210 are provided. Further, communication path 2
The fault monitoring terminal 211 is connected through 16. The communication management 207 collectively manages all terminals and lines connected to the general-purpose computer 200. When a state change of a terminal or the like occurs on a network, information about a state change including a failure code or the like is sent to the OS 206. Notice. The OS 206 that has received the notification converts the information regarding the state change into a message, displays the message on the console terminal 209, and stores the message in the message history file 210. The OS 206 also displays various other messages to be notified to the operator on the console terminal 209 and further accumulates them in the message history file 210.

The fault monitoring process 208 includes the communication information acquisition processing unit 101 and the information distribution processing unit 10 shown in FIG.
2 realizes an information acquisition distribution processing unit composed of two.
FIG. 3 shows a processing example of the failure monitoring process 208.

As shown in FIG. 3, the failure monitoring process 20
8 obtains the message every time a message is output from the OS 206 to the console terminal 209 (step S1). Then, a message ID (or number) at the head of the obtained message is obtained (step S2), and it is determined whether or not the message ID is a communication-related message ID (step S3). If the message ID is not a communication-related message ID, the process returns to step S1 and waits until the next message is output from the OS 206. If the message ID is a communication-related message ID, it is further determined whether the message ID is a line-related message ID.
It is checked (steps S4 and S5) if it is not a line-related or terminal-related message ID, the process returns to step S1 and waits until the next message is output from the OS 206. On the other hand, if the message ID is a line-related message ID or a terminal-related message ID, the message is transmitted to the fault monitoring terminal 211 through the communication path 216 using the communication function of the OS 206 (step S6). ). Then, the process returns to step S1, and waits until the next message is output from the OS 206.

The fault monitoring terminal 211 is equipped with a fault monitoring process 212, and is connected to a display device 213, an input device 214, and a history information file 215. Fault monitoring process 20 of general-purpose computer 200
8, when the line-related and terminal-related messages are sent through the communication path 216 as described above, they are received by the fault monitoring terminal 211 and the fault monitoring process 212
Is started.

The failure monitoring process 212 includes the line information analysis processing unit 103 and the line information editing processing unit 10 shown in FIG.
4, an information analysis / editing processing unit including a terminal information analysis processing unit 105 and a terminal information editing processing unit 106, an information output processing unit 107, and a detailed information output processing unit 110 are realized. FIG. 4 shows a processing example of the failure monitoring process 212.

As shown in FIG.
2 acquires the message from the general-purpose computer 200 received by the failure monitoring terminal 211 (step S1).
1) The line-related message and the terminal-related message are separated by the message ID at the head of the message (step S12).

In the case of a line-related message, the name of the line whose state has changed is acquired from the message (step S19). Next, it is determined whether the message is a failure message indicating that a failure has occurred in the line or a restoration message indicating that the failure that has occurred has been recovered (step S20).

In the case of a failure message, information (fault code, etc.) necessary for failure analysis is extracted from the message (step S21), and the communication procedure of the failed line, the cause of the failure, and other information are analyzed. (Step S22), the corresponding area on the line table is updated with the analysis result (Step S23). Here, the line table is a table prepared in advance for each line for monitoring the state of the line, and an area for setting the presence or absence of a failure, and the cause of the failure if a failure has occurred. And the like are provided. Then, based on the updated line table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S2).
4) Update information to the line table is stored in the history information file 2
15 (step S25) and step S25.
24 is displayed in a predetermined area on the screen of the display device 213 (step S2).
6). As a result, a summary of the line failure, for example, the fact that the line has entered the failure state, the name of the line where the failure has occurred, and the cause of the failure are displayed.

On the other hand, if the message is a recovery message, processing such as analysis is not necessary, so that steps S21 and S22 are skipped and the process proceeds to step S23, where a failure is detected in the corresponding area on the line table. Update that the state has transitioned to the recovery state. Then, based on the updated line table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S24), and the update information to the line table is written into the history information file 215 ( (Step S25), the screen image generated in step S24 is displayed in a predetermined area on the screen of the display device 213 (step S26). As a result, the display indicating that the line is in a failure state, which is displayed in a predetermined area of the display device 213, is changed to a display indicating that the line is in a recovery state, and the operator is notified that the line failure has been recovered. Can be recognized. Note that the display on the line for which the failure has been restored may be deleted when the operator inputs a confirmation instruction from the input device, for example, or may be automatically deleted after a certain period of time. Further, when the line failure is restored, the display of the summary of the line failure displayed on the display device may be deleted to notify the operator that the line failure has been restored.

If the message received from the general-purpose computer 200 is a terminal-related message,
The name of the terminal that has changed the status is acquired from the message (step S13). Next, it is determined whether the message is a failure message indicating that a failure has occurred in the terminal or a recovery message indicating that the failure that has occurred has been recovered (step S14).

In the case of a failure message, information (failure code, etc.) necessary for failure analysis is extracted from the message (step S15), and the communication procedure of the failed terminal, the cause of the failure, and other information are analyzed. (Step S16), the corresponding area on the terminal table is updated with the analysis result (Step S17). Here, the terminal table is a table which is prepared in advance for each terminal to monitor the state of the terminal, and is an area for setting the presence or absence of a failure, and the cause of the failure if a failure has occurred. And the like are provided. Then, based on the updated terminal table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S1).
8) Update information to the terminal table is stored in the history information file 2
15 (step S25) and step S25.
18 is displayed in a predetermined area on the screen of the display device 213 (step S2).
6). As a result, a summary of the information relating to the terminal failure, such as the fact that the terminal has entered the failure state, the name of the terminal in which the failure has occurred,
The cause of the failure will be displayed.

On the other hand, if the message is a recovery message, processing such as analysis is not required, so steps S15 and S16 are skipped and the process proceeds to step S17, where a failure is detected in the corresponding area on the terminal table. Update that the state has transitioned to the recovery state. Then, based on the updated terminal table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S18), and the updated information to the terminal table is written into the history information file 215 ( (Step S25), the screen image generated in step S18 is displayed in a predetermined area on the screen of the display device 213 (step S26). As a result, the display indicating that the terminal is in the failure state, which has been displayed in the predetermined area of the display device 213, is changed to the display indicating that the terminal is in the recovery state, and the operator is notified that the terminal failure has been recovered. Can be recognized. The display on the terminal that has recovered from the failure may be deleted when the operator inputs a confirmation instruction from the input device, for example, or may be automatically deleted after a certain period of time. Further, when the terminal failure is recovered, the display of the summary of the information relating to the terminal failure being displayed on the display device may be deleted to notify the operator that the terminal failure has been recovered.

Although not shown in the flowchart of FIG. 4, the fault monitoring process 212 is executed when the operator inputs a request for displaying detailed information from the input device 214.
A process of reading the detailed information accumulated in the history information file 215 and displaying the detailed information on the screen of the display device 213 is also performed.

FIG. 5 is a sequence chart of the above embodiment. As shown in the drawing, when the communication management 207 recognizes a line failure, the communication management 207 notifies the OS 206 that a failure has occurred in the line. The OS 206 that has received the failure notification,
Output a message. The fault monitoring process 208 obtains this message. Then, it recognizes that the message is a fault message relating to the line, and notifies the fault monitoring terminal 211 of the fault message. After performing the fault analysis, the fault monitoring process 212 of the fault monitoring terminal 211 that has received the notification displays the fault information on the screen to allow the operator to recognize that a fault has occurred on the line.

When the communication manager 207 recognizes that the line failure has been recovered, it notifies the OS 206 that the failure has been recovered. Upon receiving the failure recovery notification, the OS 206
Output a message. The fault monitoring process 208 obtains this message. Then, it recognizes that the message is a restoration message relating to the line, and notifies the failure monitoring terminal 211 of the restoration message. The failure monitoring process 212 of the failure monitoring terminal 211 that has received the notification cancels the display of the failure information on the screen and makes the operator recognize that the line failure has been recovered.

The detailed information output processing unit 306 is also provided in the fault monitoring terminal, and when a request for displaying detailed information is input from the operator via the input device 111, the detailed information is read out from the history information file 109 and is displayed on the display device 108. indicate.

Next, an example of the above embodiment of the present invention will be described.

FIG. 7 is a functional block diagram of an example according to the second embodiment of the present invention. The centralized network of this example is similar to the embodiment of FIG.
00, a plurality of terminals 201- to 201-n connected to the general-purpose computer 200 via communication lines 203-1 to 203-n such as a dedicated line, a packet network, and a public line. LAN line 205
Are connected to a plurality of terminals 202-1 to 202-n.

The general-purpose computer 200 has communication management 2
In addition, an OS 206 having an OS 07 and a failure monitoring process 401 are mounted, and a console terminal 209 and a message history file 210 are provided. Further, communication path 2
The fault monitoring terminal 211 is connected through 16. The communication management 207 collectively manages all terminals and lines connected to the general-purpose computer 200, and notifies the OS 206 of information on the state change when a state change of the terminal or the like occurs on the network. OS20 that was notified
6 uses the information about this state change as a message,
The information is displayed on the console terminal 209 and stored in the message history file 210. The OS 206 also displays various other messages to be notified to the operator on the console terminal 209 and further accumulates them in the message history file 210.

The failure monitoring process 401 includes a communication information acquisition processing unit 301 and an information distribution processing unit 30 shown in FIG.
2 realizes an information acquisition distribution processing unit composed of two.
FIG. 8 shows a processing example of the failure monitoring process 401.

As shown in FIG. 8, the failure monitoring process 40
1 acquires a message every time a message is output from the OS 206 to the console terminal 209 (step S1). Then, a message ID (or number) at the head of the obtained message is obtained (step S2), and it is determined whether or not the message ID is a communication-related message ID (step S3). If the message identification ID is not a communication-related message ID, the process returns to step S1 and waits until the next message is output from the OS 206. If the message ID is a communication-related message ID, it is further checked whether the message ID is a terminal-related message ID (step S5).
The process returns to 1 and waits until the next message is output from the OS 206. On the other hand, if the message ID is a terminal-related message identification ID, the message is transmitted to the fault monitoring terminal 211 through the communication path 216 using the communication function of the OS 206 (step S6). Then, the process returns to step S1, and waits until the next message is output from the OS 206.

The fault monitoring terminal 211 is equipped with a fault monitoring process 402, and is connected to a display device 213, an input device 214, and a history information file 215. Fault monitoring process 40 of general-purpose computer 200
1 to the communication channel 2 as described above.
When the message is sent through the server 16, it is received by the fault monitoring terminal 211, and the fault monitoring process 402 is started.

The failure monitoring process 402 includes an information analysis / edit processing section composed of a terminal information analysis processing section 303 and a terminal information edit processing section 304 shown in FIG. 6, an information output processing section 305, and a detailed information output processing section. 306 are realized. FIG. 9 shows a processing example of the failure monitoring process 402.

As shown in FIG. 9, the failure monitoring process 40
2 first obtains a message from the general-purpose computer 200 received by the fault monitoring terminal 211 (step S11). In the present embodiment, the acquired message is limited to a terminal-related message. Next, the failure monitoring process 402 acquires the name of the terminal that has caused a state change from the message received from the general-purpose computer 200 (step S13). Next, it is determined whether the message is a failure message indicating that a failure has occurred in the terminal or a recovery message indicating that the failure that has occurred has been recovered (step S14).

In the case of a failure message, information necessary for failure analysis (such as a failure code) is extracted from the message (step S15), and the communication procedure of the failed terminal, the cause of the failure, and other information are analyzed. (Step S16), the corresponding area on the terminal table is updated with the analysis result (Step S17). Here, the terminal table is a table which is prepared in advance for each terminal to monitor the state of the terminal, and is an area for setting the presence or absence of a failure, and the cause of the failure if a failure has occurred. And the like are provided. Then, based on the updated terminal table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S1).
8) Update information to the terminal table is stored in the history information file 2
15 (step S25) and step S25.
18 is displayed in a predetermined area on the screen of the display device 213 (step S2).
6). As a result, a summary of the information relating to the terminal failure, such as the fact that the terminal has entered the failure state, the name of the terminal in which the failure has occurred,
The cause of the failure will be displayed.

On the other hand, if the message is a recovery message, processing such as analysis is not required, so steps S15 and S16 are skipped and the process proceeds to step S17, where a failure is detected in the corresponding area on the terminal table. Update that the state has transitioned to the recovery state. Then, based on the updated terminal table, summary information to be displayed on the display device 213 is created and developed into a screen image (step S18), and the updated information to the terminal table is written into the history information file 215 ( (Step S25), the screen image generated in step S18 is displayed in a predetermined area on the screen of the display device 213 (step S26). As a result, the display indicating that the terminal is in the failure state, which has been displayed in the predetermined area of the display device 213, is changed to the display indicating that the terminal is in the recovery state, and the operator is notified that the terminal failure has been recovered. Can be recognized. The display on the terminal that has recovered from the failure may be deleted when the operator inputs a confirmation instruction from the input device, for example, or may be automatically deleted after a certain period of time. Further, when the terminal failure is recovered, the display of the summary of the information relating to the terminal failure being displayed on the display device may be deleted to notify the operator that the terminal failure has been recovered.

Although not shown in the flowchart of FIG. 9, the failure monitoring process 212 is executed when the operator inputs a request for displaying detailed information from the input device 214.
A process of reading the detailed information accumulated in the history information file 215 and displaying the detailed information on the screen of the display device 213 is also performed.

[0063]

As described above, according to the present invention, the following effects can be obtained.

The operator can more surely recognize the terminal state change. The reason is that when a failure occurs in the terminal, an outline is displayed on the display device of the failure monitoring terminal, but this display device is different from the console terminal of a general-purpose computer, and only the information related to the terminal or in addition to it This is because displaying only the information on the line reduces the possibility that the operator will overlook the occurrence of the failure.

The terminal status can be monitored without significantly increasing the load on the general-purpose computer. The reason is that, on the general-purpose computer side, only processing related to terminal-related messages or only line-related messages from the messages output from the OS to the console terminal and transmitting them to the fault monitoring terminal is performed. This is because message analysis, editing, display, and the like are performed on the fault monitoring terminal side.

The detailed information can be obtained quickly,
In addition, the load on the general-purpose computer accompanying this can be eliminated. The reason is that the detailed information is stored in the history information file on the failure monitoring terminal side, so that the acquisition of the detailed information can be performed only by the processing on the failure monitoring terminal side.

In a configuration in which not only monitoring of the terminal status but also monitoring of the line status is performed, if a fault occurs in the terminal due to a line fault, the operator can recognize the fault and isolate the fault location. Becomes easier.
