DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network management system and, more particularly, to a system for notifying an operator of an alarm event associated with construction work of a network device such as a packet switch, a telephone switch, and a transmission device.

[0002]

2. Description of the Related Art Conventionally, regarding the management and output of faults in this type of network management system, as described in, for example, Japanese Patent Application Laid-Open No. 2-234597, an alarm generated at the time of construction work is masked to obtain a true Although an alarm mutual mask method that outputs only an alarm due to a failure as a failure has been proposed, the handling of higher-level reflection associated with the configuration of the inclusion tree of the construction target device has not been determined.

[0003] In addition, as a method of handling the higher reflection associated with the configuration of the inclusion tree of the construction target device, for example, when a failure occurs during the construction work time, the higher reflection of the alarm event of the failure of the construction target device is performed. However, when a failure is restored during the construction work time, there is a configuration in which an alarm event for restoration of the failure of the construction target device is reflected at a higher level.

As described in Japanese Patent Laid-Open No. Hei 5-207015, a network state in which the influence of a fault that has occurred on a device is counted and the type of the fault is determined by comparing the count value for each monitored object. Management methods have also been proposed.

[0005]

However, the conventional network management systems described in the above publications have the following problems.

A first problem is that fault management for managing occurrence / recovery of a fault represented by an alarm event and management of a fault alarm event due to a construction work are performed for each construction target device.

[0007] In the case of performing higher-level reflection in the configuration of the inclusion tree, if only the alarm event for restoration of a failure of a device to be constructed is reflected in the upper-level, the operator can reflect the failure of the device to be constructed higher even during the construction work period. Is continued, so that it is not possible to distinguish whether or not the real failure is reflected on the upper level, which confuses the network monitoring work of the operator.

[0008] The reason is that, regarding a failure occurrence / recovery alarm event which is naturally predicted to occur due to construction work, the operator is notified only of the recovery alarm event without notifying the occurrence alarm event. That's why.

[0009] The second problem is that, at the end of the construction work, the occurrence of the failure in the construction work time zone is not reflected at the top even though a failure has occurred in the actual network equipment. A mismatch occurs in the notification.

[0010] The reason for this is that regarding the management of faults due to construction work, it is only necessary to judge whether or not to reflect the alarm event at the higher rank, and the occurrence / recovery of faults during the construction work time period is not accumulated. This is because the state of the obstacle and the state of the obstacle at the end of the construction work do not match.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems, and has been made in view of the above problems, and has a work management capable of suppressing a notification of an alarm event accompanying a construction work to an operator and preventing confusion of the operator in a network monitoring work. An object of the present invention is to provide an alarm event suppression method.

[0012]

To achieve the above object, the present invention provides a network management system for notifying an operator of an alarm event from a network device to be managed, the network connection unit being connected to the network device.

The present invention provides a work management alarm event suppression method characterized in that a system event is reflected at a higher level .

In the work management alarm event suppressing method according to the present invention, in the work management section, the work management section manages a construction work time zone in which a construction work is scheduled and a construction target device, and It is preferable to suppress the notification of the alarm event from the device to the operator.

Further, in the work management alarm event suppressing method according to the present invention, the fault management unit may include means for reflecting an alarm event of occurrence and recovery of a failure of a lower device in a containment tree configuration of the network, and an operator inputting the means. Means for accumulating the construction work time zone in which the construction work is to be scheduled and the construction target device, and at the start of the construction work time zone, the upper reflection of the alarm event from the lower device serving as the construction target device in a pseudo manner. Means for restoring, means for stopping higher-order reflection of an alarm event from the lower device serving as the construction target device in the construction work time zone, and means for stopping the reflection of the alarm event from the lower device serving as the construction target device in the construction work time zone. Means for accumulating alarm events, and updating the accumulated alarm events at the end of the construction work period. Means for reflecting, may is intended to include.

According to the work management alarm event suppression method of the present invention, an operator is not notified of a failure occurrence / recovery alarm event which is naturally predicted to occur due to construction work of a network device to be managed. ,
An operator can determine and recognize only a failure to be monitored due to a failure of a network device or a failure that hinders operation.

[0016]

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

FIG. 1 is a diagram showing a configuration of a work management alarm event suppression system according to an embodiment of the present invention.

As shown in FIG. 1, the work management alarm event suppression method according to the present embodiment can be applied to a network management system for managing the network 20.

The workstation 21 comprises a display 21a and a workstation body 21b. The workstation main body 21b includes a network connection unit 22 connected to a network device of the network 20, a failure management unit 23 that processes an alarm event 27 received via the network connection unit 22,
A failure display unit 24 for displaying information about a failure in a predetermined format on the display 21a, a work management unit 25 for managing construction work of the network device, and a state storage unit 26 for holding information about the state of the network device. Included as main components.

The network connection unit 22 receives an alarm event 27 sent from a network device of the network 20 to be managed and sends it to the fault management unit 23.

The fault management unit 23 manages and manages the occurrence / recovery of a fault for each region, station, device, etc. (hereinafter, also simply referred to as "device") having a containment tree structure.
In accordance with an instruction from the work management unit 25, the reflection of the alarm event of the lower device to the higher device (referred to as “higher reflection”) is stopped during the construction work time zone, and the information during that period is sent to the state storage unit 26.

The fault display unit 24 displays the alarm event sent from the fault management unit 23 on the display 21a in the form of a list or a network monitoring diagram.

The work management unit 25 has an interface with the operator, and takes in the construction schedule device name, the scheduled start time and the end time of the construction work input by the operator. The work management unit 25 monitors the time, and when the scheduled work start time comes, instructs the failure management unit 23 not to reflect the occurrence / recovery of the failure occurrence / recovery for the device to be constructed, and sets the scheduled work start time. When the work end time comes, the failure management unit 23 is instructed to perform higher-level reflection on the construction-scheduled device.

The status accumulation unit 26 accumulates and manages the response to the occurrence / recovery of a fault and the status of the device that has not been reflected during the construction work. When the end of the construction work is notified by an instruction from the work management unit 25, the failure management unit 2
Reference numeral 3 reads the status of the corresponding device from the status storage unit 26, and if a failure has occurred, reflects the higher level.

FIG. 2 is a schematic diagram for explaining an example of fault management by the work management alarm event suppression method according to one embodiment of the present invention.

As shown in FIG. 2, it is assumed that the state of each device having the configuration of the containment tree changes from state (a) to state (g) over time. 10 indicates a normal state, 11 indicates a state in which a corresponding unit failure has occurred, and 1
Reference numeral 2 denotes a state in which a failure of a lower device is reflected at a higher level and a higher reflection failure is displayed, and reference numeral 13 denotes a work setting position serving as a reference for stopping higher reflection.

The operator sets the construction work time zone 14 by inputting the work start time 15 and the work end time 16, and designates a setting place 13 during construction work and sets a device below this as a construction scheduled device. I do.

In normal times other than the construction work time zone 14, as shown in the state (a), the occurrence of the failure is reflected in the device higher than the part where the corresponding part failure 11 has occurred, and these are reflected in the higher reflection failure. Represented as display 12. When the failure of the lower-level device is restored, as shown in the state (b),
Similarly, the recovery of the failure of the lower-level device is reflected on the upper level.

After that, when the scheduled work start time 15 comes, as shown in the state (c), the faults occurring below the working set point 13 are not reflected on the upper level. Also, when the failure of the lower-level device is restored, the restoration of the failure is not similarly reflected in the higher order as shown in the state (d). If there is a failure in the lower device that has been reflected higher before that time, this is restored in a pseudo manner, so that the failure of the lower device is not shown to the operator.

At the scheduled work end time 16, if the failure of the equipment below the work setting location 13 set in the construction work time zone 14 continues to occur, The failures accumulated for the devices below the part of the set point 13 are read out and reflected on the higher order.

In this way, during the construction work, the network monitoring work is performed without the operator being conscious of the occurrence / recovery of the trouble caused by the construction work of the devices below the part set during the work 13. Will be able to do it.

While one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, but includes various embodiments according to the principle of the present invention.

[0033]

As described above, according to the work management alarm event suppression method of the present invention, during the construction work, the occurrence / recovery of a failure that is naturally predicted by the construction work for devices below a predetermined part is performed. Since no notification is given to the operator, confusion of the operator in the network monitoring work is prevented, and the network monitoring work can be performed without any awareness of the construction work.

Further, according to the work management alarm event suppression method of the present invention, the occurrence / recovery of failures during the construction work time period is accumulated, so that the reflection of the failure of the construction target device is not continued. Since only the actual occurrence of a fault is reflected as a fault, the fault in the host device can be easily recovered.

Further, according to the work management alarm event suppression method of the present invention, the occurrence / recovery of a failure during the construction work time period is accumulated, so that a failure occurs in an actual network device at the end of the construction work. However, since the occurrence of a failure in the construction work time zone is appropriately reflected in the higher rank, it is possible to prevent occurrence of inconsistency in the notification of the failure to the operator.
