DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network monitoring system, and more particularly, to a fault information processing method for a network monitoring system that monitors a management target of devices and lines of different types, collects status, and processes fault information. About.

[0002]

2. Description of the Related Art In the fault information processing of a network monitoring system, fault information occurring in devices (devices, lines, etc.) (managed objects) constituting a network is notified / displayed to a network administrator via the monitoring system. Perform processing.

In the conventional network management method,
Since the failure monitoring and the failure information display are executed by the common processing unit, the process of displaying the failure information to be managed and the failure display contents depend on the type of the management target.

A method has also been proposed in which fault information relating to a management target is determined based on the content of a message from a monitoring unit to be managed, and the fault information is displayed.

[0005] Furthermore, a method of displaying fault information that does not depend on the type of management target has been proposed.
It was necessary to hold information in a format common to the management target types for each management target.

For example, the above-mentioned conventional network management method is disclosed in Japanese Patent Application Laid-Open No.
283139.

In the above-mentioned Japanese Patent Application Laid-Open No. 9-223092, in order to manage a network, information is held as one object for each connected device, and is generated on the network configuration diagram based on the information of the object. A state symbol is generated, displayed and presented to the network administrator. If the connected device is abnormal, the information of the object is updated based on the received failure information, and the updated state symbol is displayed on the network configuration diagram. There is disclosed a network management method and system for generating and displaying a network device and performing a failure recovery operation on a connected device based on the displayed information.

[0008] The above-mentioned Japanese Patent Application Laid-Open No. 2-283139 discloses a network fault data management system in which information from a management device is provided in a unified format.

[0009]

However, the above-mentioned prior art has the following problems.

The first problem is that the process for displaying fault information and the fault display content depend on the type of management target, so that the process for displaying fault information cannot be shared.
When a management target of a different type is added, it is necessary to change the processing.

The reason is that the processing for displaying the fault information of the management target and the content of the fault display are of a method depending on the type of the management target. Also, the means for processing messages with different contents notified from the management targets of different types also depends on the type, and it is necessary to change the process of displaying a failure by adding a message type or the like.

A second problem is that when fault information is handled in a common format, management targets of different types are added, and when fault information is added or changed, even when the fault information in the common format is changed. It is likely to be necessary.

[0013] The reason is that it is difficult to define fault information in a format that is commonly valid for all types of managed objects.

The third problem is that the displayed fault information depends on information held in the object to be managed.
It is difficult to change the display contents.

The reason is that there is no means for displaying and defining fault information and related information that differs depending on the type of the management target, or the display processing needs to be changed.

A fourth problem is that, when a managed object having a fault has a relationship with a plurality of managed objects, fault information of the related managed objects cannot be displayed at the same time. This means that when displaying the failure information, it is not possible to specify the related management target.

The reason is that there is no means for designating the attribute of the third problem and the attribute of the related management target as the display target.

The storage device 400 stores the management information data 40
1. Includes failure information definition data 402.

The management information data 401 holds management information on all management targets managed by the monitoring system.
A list of attributes and their values (attribute values) is included for each management target (see FIG. 3). For example, the management target “A1” in FIG.
Indicates “type”, “failure list”, “status”, “node name”, “address”, “contact”, “operating time”, “state of card 1”, “state of card 2” as management information. The monitoring process unit 102 that has attributes such as “A1” and monitors the management target “A1” sets and holds a value for each attribute.

The fault information definition data 402 includes a list of attributes to be displayed as common fault information for all management targets,
A list of attributes to be displayed as fault information is included for each type of management target (see FIG. 4). For example, referring to FIG.
For managed objects having the type attribute of “node A” (managed nodes “A1”, “A2”, “A3”),
The attributes of "status", "node name", "address", "operating time", and "status of card *" are displayed as fault information, and "failure list" is used as fault information common to all management targets.
Is to be displayed.

In the fault information definition data 402, attributes having the same characteristics can be grouped and expressed. In the example of the managed node "A1", "state of card *" corresponds to When searching the management information data 401, the information processing section 103 recognizes “state of card 1” and “state of card 2” as its attributes.

The data processing device 100 includes a communication control unit 10

07, a management target input processing unit 108.

The communication control unit 101 controls a communication protocol for communicating with a communication device or the like to be managed.

The monitoring process unit 102 is composed of individual monitoring processes modularized for each type of management target (device type), and each monitoring process has its attributes and values as a result of collecting the status of the management target. Is written to the management information data 401 via the failure information access control unit 105. The attribute that the monitoring process unit 102 writes in the management information data 401 may be unique to the type of the management target, except for the “type” attribute of the management target. There is no need to unify the format of the file, and management information unique to the management target can be held.

At this time, the monitoring process unit 102
The failure information processing unit 103 is notified of which of the managed objects has undergone a state change using a common format including only data for identifying the managed objects.

The failure information processing unit 103 that has received the notification of the status change of the management target reads out the “type” attribute from the management information data 401 of the management target via the failure information access control unit 105, and Determine the type.

When a management target is designated by the management target input processing unit 108, the failure information processing unit 103 reads the failure information definition data 402 defined by the type of the management target (this data is Definition holding unit 1
04 internally), identifies the attribute described in the fault information definition corresponding to the type of the management target, and extracts the attribute value of the corresponding attribute from the management information data 401, The data is passed to the fault information display unit 106 as data.

For example, when the management target “A1” is specified by the management target input processing unit 108, the attribute value of the type is “node A”, and the fault information definition of the type “node A” is Read from the definition data 402.

Referring to FIG. 4, the fault information definition of the node A is “state”, “node name”, “address”, “operating time”, and “state of the card *”. The attribute value is read from the management information data 401 and passed to the fault information display unit 106 as data.

The failure information display unit 106 displays the data passed here on the output device 200 as the failure information to be managed. By this means, even if the failure information differs for each management target type, the failure information definition data 402
, The attribute defined as the failure information for each type of management target is identified, so that the failure information (attribute) unique to the management target collected by each monitoring process unit 102 is shared by the common processing (failure information processing unit 103). Can be displayed.

Further, when it is specified from the management target input processing unit 108 to output data common to all management targets, the failure information processing unit 103 reads the failure information definition data 402 (this data is Information definition holding unit 1
04), an attribute common to all the management targets is identified, and the attribute values of the corresponding attributes are extracted from the management information data 401 for all the management targets, and passed to the fault information display unit 106 as data.

For example, referring to FIG. 4, since the fault information definition common to all the management targets is a “failure list”, the attribute values of this attribute are extracted from the management information data 401 for all the management targets, and the fault information is displayed. The data is passed to the unit 106 as data.

The fault information display unit 106 displays the data passed here on the output device 200 as fault information common to all management targets.

By this means, it is possible to display the common failure information of the management target in common processing based on the attribute set in the management information data 401 by each monitoring process unit 102.

The failure information definition input processing unit 107 writes the failure information definition for each management target type input via the input device 300 into the failure information definition data 402 and simultaneously stores the failure information definition in the failure information definition holding unit 104. It notifies that the failure information definition data 402 has been updated.

The failure information definition holding unit 104 reads the failure information definition data 402 into a memory. By this means, even when a new monitoring process unit 102 is added due to the addition of a management target of a different type, and when the management information attribute of the monitoring process unit 102 is added or changed, the management target Fault information definitions can be added or changed as needed, so that fault occurrence status and related management information can be displayed without changing the processing (program) of the common fault information processing unit And

As a result, it is possible to reduce the number of development steps for a new process in order to display the fault information of the managed object that has been passed or changed.

The reason is that the monitoring process unit and the fault information processing unit perform fault management using the fault status of the management target and the attribute related to the management information held in the management information data which is a common data holding unit. The notification of the state change from the monitoring process different for each management target type to the failure information processing unit is performed using a common format including only the data for identifying the management target, and the display processing of the failure information for each management target type includes: This is done by referring to fault information definition data that can be redefined for each management target type.

The second effect is that when monitoring the management targets of devices and lines of different types, the failure information can be displayed by the common fault information processing without performing the fault information display processing for each management target type. It can be displayed. As a result, the operator who performs the fault monitoring performs the fault display by the common operation and can recognize the fault information for each management target type, so that the network operation and maintainability is improved.

The reason is the same as that of the first effect.

A third effect is that an attribute to be displayed as fault information can be defined for each type of management target. As a result, for each network monitoring system, it is possible to customize the display contents of fault information to be managed and related information, and it is possible for a network administrator to display necessary management information, thereby improving network operation and maintenance. Is improved.

The reason is that a means for inputting fault information for each management target type is prepared, and the common fault information processing unit refers to the management information for each management target type and displays the fault information of the management target. It is.

A fourth effect is that fault information common to all managed objects can be displayed. As a result, it is possible to display a list of the failure information common to all the management targets, and the operator can recognize the failure information occurring in the network at a glance, thereby improving the maintainability of the network.

The reason for this is that the common attribute set in the management information data by the monitoring process for each management target type can be registered as a failure information definition and displayed as failure information.
