Abstract

PURPOSE:To accurately judge the significance of a fault in a network(NW) to be monitored by an NW monitoring device by deciding the significance of the fault and informing plural network monitoring devices of fault information including the fault significance and fault contents by the NW monitoring device when the fault occurs or is restored. CONSTITUTION:When the fault occurs or is restored in an NW 1(1) to be monitored, a NW monitoring device 2(1) receives fault information b1 to indicate either the occurrence or the restoration of the fault with a reception part 4(1). A significance deciding part 6(1) takes out composition information (c) corresponding to the fault information b1 from an NW composition information part 5(1) based on the fault information b1. The significance deciding part 6(1) decides the significance of the fault based on the composition information (c) and the fault information b1 and classifies the significance of the fault into either serious significance or slight significance for the fault. Information (d) about the significance of the fault is displayed from the significance deciding part 6(1) onto a screen display part 7(1). Thus, the significance of the fault can be accurately judged.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a failure notification system for notifying failure information from a network monitoring device (-NW monitoring device) to multiple network monitoring devices (multiple NW monitoring devices) [Conventional] [Technology] Conventionally, each NW monitoring device monitors a monitored network (monitored NW) and notifies multiple NW monitoring devices of failure information indicating the occurrence of a failure or recovery within the monitored NW. Based on the failure information, detailed configuration information of the network configuration was used to check the importance of the failure.

[Problem to be solved by the invention]

As described above, conventionally, the degree of importance of a failure has been checked using detailed configuration information in a plurality of NW monitoring devices, which has the following drawbacks.

The importance of the same fault differs depending on the configuration of the monitored NW. Since the devices that make up a monitored NW are arbitrarily provided for each network, a multiple NW monitoring device can
Each NW to be monitored must have W configuration information. However, the detailed configuration information regarding monitored NWs is large in number even if it covers only one network, and even more so if it covers all monitored NWs. Therefore, it is difficult for a plurality of NW monitoring devices to have detailed configuration information of all monitored NWs. As a result, multiple N
The W monitoring device was unable to accurately check the importance of the failures with respect to the failure information notified from each NW monitoring device, and ended up determining all failures as severe failures.

An object of the present invention is to solve the above-mentioned conventional problems, and to determine the degree of failure severity in multiple NW monitoring devices by notifying the multiple NW monitoring devices of failure information indicating the failure details and failure importance from the NW monitoring device. The purpose of the present invention is to provide a failure notification method that facilitates.

[Means to solve the problem]

The present invention provides a system for reporting failure information of a monitored network from a plurality of independent work monitoring devices each monitoring one monitored network to a plurality of network monitoring devices monitoring a plurality of the monitored networks. The above-mentioned network monitoring device uses a notification method when a failure occurs or is restored in the monitored network to be monitored.
The present invention is characterized in that the degree of importance of the failure is determined, the degree of importance of the failure and the details of the failure are included in the failure information, and the information is notified to the plurality of network monitoring devices.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a failure notification system according to an embodiment of the present invention.

The fault notification method uses one monitored NWIII (~1(n)
) - NW monitoring device 2 fl) (~2 (n
) Failure information fIi indicating the failure details and failure severity from )
a.

The method of transmitting (~an) to multiple NW monitoring devices 3 The monitored NW 1 fl) (~1 (n)) is, for example, a data communication or telephone communication network, and the type and number of devices that make up the network are is each monitored NWill (~
1(n)).

-NW monitoring device 2 (11 (~2 (n)) receives failure information b1 (11 (~2 (n)) from monitored NW1 (1) (~1 (n)).
Receiving unit 4 (11(~4 (n)
), and the NW configuration information section 5 [1] (~5 (
), the failure information b1 from the receiving unit 4(1) (~4(n)), and the configuration information C from the NW configuration information unit 5f1) (~5(n)). an importance determination unit 6(1) (~6(n)) that determines the importance of the failure, classifies it as severe or mild, and forms failure information al (~an) indicating the importance of the failure and the content of the failure; The screen display unit 7 (11 (~7
(n)) and the transmitting unit 8 (11 (~8( n)).

The multiple NW monitoring devices include -NW monitoring devices 2(1) to 2(n
) for receiving the failure information Mal~a from
and a detailed configuration information unit that has a predetermined amount of detailed configuration information regarding the configuration of the monitored N W 1 (1) to 1 (n) and performs predetermined processing based on the failure information a, ~a, from the receiving unit 9. 10.

Next, the operation of this embodiment will be explained.

When a failure occurs or is restored in the monitored NW 1 (11), the -NW monitoring device 2 (1) receives the reception unit 4 (
1) receives failure information indicating failure occurrence or recovery. The receiving unit 4(1) sends the received failure information bl to the importance determining unit 6(1). Based on the failure information b1 from the receiving unit 4(1), the importance determination unit 6(1) extracts configuration information C corresponding to the failure information b1 from the NW configuration information unit 5(1).
Take out. With this configuration information C and failure information b1,
The importance determining unit 6(1) determines the importance of a failure and classifies the failure as severe or minor. This failure severity information d is sent from the importance level determination unit 6(1) to the screen display unit 7(1), and is displayed on the screen by the screen display unit 7(1). Further, the importance level determining unit 6 (1) forms failure information a indicating the failure importance level and failure details, and transmits the failure information to the transmitting unit 6 (1).
Output to (1).

The transmitting unit 8(1) transmits the failure information a1 from the importance determining unit 6(1) to the multiple NW monitoring device 3.

The multiple NW monitoring device 3 receives the fault information a1 from the -NW monitoring device 2(1) through the receiving section 9, and sends the fault information a from the receiving section 9 to the detailed configuration information section 10. The detailed configuration information unit 10 recognizes the content of the failure and the severity of the failure based on the failure information *1a+ from the receiving unit 9, and identifies the monitored N W 1 (
After performing predetermined processing based on the detailed configuration information of No. 11,
A plurality of NW monitoring devices 3 are monitored N W 2 (11, -N
Necessary monitoring control is performed on the W monitoring device 1 (1).

〔Effect of the invention〕

As explained above, the fault notification method of the present invention is such that: - When a fault occurs or is restored in a network to be monitored, the network monitoring device determines the importance of the fault, and determines the fault importance and the details of the fault. Since the failure information is included in the failure information and notified to the multiple network monitoring devices,
The multiple network monitoring devices do not need to have a large amount of unnecessary information, and even if they cannot have a large amount of information, there is an effect that they can accurately judge the importance of a failure. Furthermore, there is no need to make the same determination redundantly in the network monitoring device and the multiple network monitoring devices.
