Abstract

PURPOSE: To quickly detect and inform a highly emergent and important fault when a convergent state is generated in a system due to the generation of many faults. CONSTITUTION: When the generation of a fault is reported from each of devices A to N to be managed, a data judging part 21 judges whether the fault data are important fault data or not and stores the data in a 1st buffer 22 in the case of important fault data or stores the data in a 2nd buffer 23 in the case of light fault data. A data transmission switching part 24 weights the 1st and 2nd buffers 22, 23 at a prescribed rate, reads out respective fault data from the buffers 22, 23 based upon the weight and displays the read data on a fault display part 3. Since important fault data stored in the 1st buffer 22 can be displayed with priority, a highly emergent and important fault can quickly be detected and reported even when a convergent state is generated in the system due to the generation of many fault.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault alarm output control system for displaying an output of a fault occurring in a network.

[0002]

2. Description of the Related Art As a technique similar to the output display control of a fault alarm of this type occurring in a network, there is one disclosed in Japanese Patent Laid-Open No. 5-30157, for example. Such a network management system includes a central management device 11 and a display unit 1 as shown in FIG.
The display unit 12 is configured to display a fault on the display unit 12 in response to a fault alarm notification from each of the managed devices A to J. Here, each managed device is divided into managed devices A to F that are operated all day, and managed devices G to J that are suspended during the nighttime hours, and are subject to actual failure alarm notification and suspension of operations. It is configured so that a failure notification can be immediately determined.

That is, as shown in FIG. 3, the central management device 11 constantly monitors the operating time period of each management target device, and, for example, when a failure notification is received from the management target device G, the management is performed. If the target device G is in the operating time zone, a failure alarm is displayed on the display unit 12 as a failure has occurred in the management target device G. Further, when the failure notification is received from the managed device G, if the managed device G is outside the operating hours, the failure notification is determined to be a notification of operation stop, and the fact is displayed on the display unit 12.

[0004]

As described above, in the conventional network management system, when a fault notification is received from the managed device, a fault alarm is notified due to the occurrence of a fault in the managed device, or the management thereof is performed. Whether the failure is notified due to the stop of the operation of the target device is separated according to the operating time zone of the managed device. Therefore, since the failure notification from each managed device outside the operating hours is not displayed as a true failure alarm, the network administrator generates the alarm during the operating hours and the display unit 1
It is possible to recognize the true failure alarm displayed in 2 and maintain the corresponding managed device, and thus reduce the burden on the network administrator.

However, when there are a large number of managed devices, and when the managed devices in operation are simultaneously notified of failure alarms and become in a congestion state, these failure alarms are generated in the conventional network management system. Regardless of whether the fault is a critical one with a high degree of urgency or a minor one, it is sequentially displayed on the display unit 12 in the order of notification. Therefore, there is a problem that detection of a failure that is important for the system and that requires urgent repair is delayed. Therefore, it is an object of the present invention to promptly detect and notify an important fault having a high degree of urgency even when a large number of faults occur in the system and a congestion state occurs.

[0006]

In order to solve such a problem, the present invention provides a data judging section for judging whether or not each failure data notified from each management target apparatus is important failure data, and an important failure. A first buffer for accumulating data, and a second buffer for accumulating minor failure data among each failure data
And a data transmission switching unit for weighting the first and second buffers at a predetermined ratio and reading out and displaying the respective fault data of the first and second buffers on the display unit according to the weighting. Is. Further, the data determination unit stores the data in the second buffer when the first buffer becomes full due to the notification of the respective critical failure data from the respective management target devices due to the frequent occurrence of the serious failures in the respective management target devices. The faulty data present is discarded and important faulty data is accumulated in the second buffer.
The failure data of the first and second buffers are sequentially displayed on the display unit. In addition, the data determination unit is the head of the first buffer when a significant failure occurs frequently on the side of each management target device and each management target device notifies each critical failure data to fill the first and second buffers. A message indicating that the buffer is full is stored in the section.

[0007]

When each fault data is notified from each device to be managed, the data determination unit determines whether or not the fault data is important fault data, and if the fault data is important fault data, stores it in the first buffer. If the data is a light failure data, the data is stored in the second buffer, and the data transmission switching unit weights the first and second buffers at a predetermined ratio, and according to this weighting, each failure data in the first and second buffers. Is read out and displayed on the display unit. As a result, the important fault data accumulated in the first buffer can be preferentially displayed, so that even if a large number of faults occur in the system and a congestion state occurs, an important fault with a high degree of urgency. Can be promptly detected and notified. Further, when a significant failure occurs frequently on each managed device side and each important failed data is notified from each managed device and the first buffer becomes full, the failed data accumulated in the second buffer is discarded. And stores important fault data in the second buffer,
And each fault data in the second buffer is sequentially displayed. As a result, even when the important faults occur frequently and the congestion occurs, the respective important faults can be sequentially detected and notified. In addition, each of the managed devices causes more serious failures, and each managed device notifies each of the critical failure data.
When the second buffer becomes full, a message indicating that the buffer is full is stored at the head of the first buffer. As a result, since this message is displayed on the display unit, the network administrator can easily recognize that there are many important failures in the system.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a network management system to which the present invention is applied. The network management system 1 comprises a failure processing section 2 and a failure display section 3. Here, the failure determination unit 2 includes a data determination unit 2
1, a first buffer 22, a second buffer 23, a data transmission switching unit 24, and a table unit 25 are provided. Further, A to N represent managed devices including lines and the like,
It is managed by the network management system 1.

By the way, in the network management system 1 configured as described above, when the fault data (alarm data) generated in each of the managed devices A to N and notified from each of the managed devices is input, the fault in the fault processing unit 2 occurs. Processing is performed, the processing result is sent to the failure display unit 3 and displayed in the order of sending, and the failure is notified to the network administrator. The network manager recognizes the managed device to be maintained from the display status of the failure display section 3 and repairs the managed device.

Here, in the first buffer 22 in the failure processing unit 2 which processes the failure data, important failure data which has a high degree of urgency and is desired to be detected preferentially is accumulated. Further, in the second buffer 23, minor fault data that should be suppressed on the managed device side that can be ignored by the network administrator is stored. It should be noted that the failure data includes an identification code indicating the failure type, and the table unit 25 in the failure processing unit 2 stores data indicating the urgency level of the failure corresponding to the identification code of each failure data. Has been done.

Now, for example, if a fault occurs in the managed device A and this fault data is notified to the network management system 1, the data discriminating unit 21 in the fault processing unit 2 will include the fault included in this fault data. The identification code of the type is detected, and the table unit 2 corresponding to this identification code
Refer to the urgency data in 5. Then, it is determined whether or not this failure data is important failure data of high urgency that must be immediately repaired by the network administrator,
If it is the important fault data, it is stored in the first buffer 22. If the fault data is a mild fault data that does not require maintenance by the network administrator, it is stored in the second buffer 23.

In this way, the fault data notified from each managed device is stored in the first buffer 22 or the second buffer 23 according to the urgency. When each fault data is accumulated in the first buffer 22 and the second buffer 23 in this way, the data transmission switching unit 24 reads each fault data from each buffer and sends it to the fault display unit 3 for fault display. In this case, the data transmission switching unit 24 stores, for example, 3 data stored in the first buffer 22.
After displaying one piece of important failure data on the failure display unit 3 sequentially, weighting control is performed to display one piece of failure data accumulated in the second buffer on the failure display unit 3. That is, the data transmission switching unit 24 weights the first and second buffers at a ratio of 3: 1 respectively, and reads the fault data of each buffer at a ratio according to this weighting, and the fault display unit 3 Control to be displayed on.

Thus, the present network management system 1
Then, a first buffer 22 for accumulating important fault data and a second buffer 23 for accumulating minor fault data are provided, and when each fault data accumulated in each buffer is to be displayed, a predetermined ratio is used for each. Since the buffer is accessed and each failure data is displayed, priority is given to failure information with a high degree of urgency even during failure congestion when a large amount of important failure data and minor failure data is notified from each managed device. It can be instantly detected and displayed. If the fault data is stored only in the first buffer 22, the data transmission switching unit 24 sends only the important fault data to the fault display unit 3 for display. Further, when the fault data is stored only in the second buffer 22, only the mild fault data is sent to the fault display unit 3 and displayed.

[0016] Here, when each management target device has a large number of urgent failures, and each management target device notifies the critical failure data, the first buffer 22 is filled with the critical failure data. Become. In this case, when the data determination unit 21 detects the full state of the first buffer 22, the light failure data accumulated in the second buffer 23 is discarded and the important failure data is accumulated in the second buffer 23. Control to do. At this time, in the data transmission switching unit 24, when the full state of the first buffer 22 is detected, the above-described weighting control for displaying each failure data accumulated in each buffer according to a predetermined ratio is not performed, First
Display the important failure data in the buffer 22 of
After this is completed, control is performed to display the important fault data in the second buffer 23, and the important faults are sequentially notified to the network administrator side.

Under such a circumstance, if more urgent failures occur on each managed device side, the second buffer 23 also becomes full. When the data determination unit 21 detects the full state of the second buffer 23, the data determination unit 21 controls the accumulation of this important fault data from the beginning of the first buffer 22, but if the first buffer 22 is full at this time. Then, the head portion of this buffer 22 is emptied and a message to the effect that "the buffer is full and the fault data is discarded" is inserted into the head portion. In this way, the message inserted at the beginning of the first buffer 22 is
Is displayed on the screen and is notified to the network administrator. Therefore, the network administrator can recognize that there are many urgent failures in the system.

[0016]

As described above, according to the present invention, when each fault data is notified from each device to be managed, the data determination unit determines whether or not the fault data is important fault data, and the important fault is detected. The data is stored in the first buffer, and the lightly disturbed data is stored in the second buffer. The data transmission switching unit weights the first and second buffers at a predetermined ratio, and the weighting is performed. According to the above, since the respective fault data of the first and second buffers are read out and displayed on the display unit, the important fault data accumulated in the first buffer can be preferentially displayed, and therefore the system Even if a large number of faults occur and a congestion state occurs, it is possible to promptly detect an important and highly urgent fault and notify the network administrator. Further, when a significant failure occurs frequently on each managed device side and each important failed data is notified from each managed device and the first buffer becomes full, the failed data accumulated in the second buffer is discarded. The important fault data is stored in the second buffer and the fault data in the first and second buffers are sequentially displayed. Therefore, even when the important faults occur frequently and congestion occurs, Failures can be sequentially detected and notified. Further, when more important failures occur on each managed device side, and each important failed data is notified from each managed device, and the first and second buffers become full, a buffer is added to the head of the first buffer. Since a message indicating that the computer has become full is accumulated, this message is displayed on the display unit, so that the network administrator can easily recognize that there are many serious failures in the system.
