Abstract

PURPOSE:To enable alarm definition detected by the system to be difined by a user by displaying only the required information of alarms generated in a network only when it is required in the network monitor system. CONSTITUTION:Only the alarm registered by a user using an alarm registration part 8, is detected by an alarm detection part 12 at a main body part 6 based on a message 4 and a terminal part 7 is informed of the alarm by an alarm information part 13. The terminal part 7 receiving that information performs a processing such as alarm display 16 or node control 17 by an alarm display part 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network monitoring system for electronic control devices such as electronic exchanges, and more particularly to a network monitoring system with a user customization processing function for alarm display.

[0002]

2. Description of the Related Art In a conventional network monitoring system, a received message is used as an alarm as it is, and an alarm is displayed by a fixed process. Then, the operation of selecting the alarm to be displayed can be performed only slightly by designating the message class to which the message belongs. Also, the class to which a message belongs has been fixedly determined.

[0003]

In the above-mentioned conventional network monitoring system, for example, even if the message is important to the user, if it is a message of a class of low importance, no alarm is displayed. Also, the same message is the number 1
I want to monitor as an alarm only when it occurs 0 times in succession, but the alarm is displayed every time. Furthermore, because the method of suppressing the alarm display is limited to specifying the display class, it is difficult to display the information that the user really needs, such as being unable to display only the alarms of interest. There are drawbacks.

Since the alarm display processing is fixed,
It was also not possible to specify that an operation should be automatically performed at the same time the alarm is displayed when an alarm occurs.

[0005]

A network monitoring system according to the present invention includes a main body for receiving and accumulating a message indicating a change in the state of a node generated by a large number of electronic control units constituting a network, and the main body. In a network monitoring system having a terminal unit for notifying a user of a network state based on the stored messages, the terminal unit includes an alarm registration unit for registering an alarm definable by the user, Alarm display means for displaying the occurrence of the alarm to the user based on the alarm notification data, and the main body section shows alarm detection means for analyzing the message and detecting the occurrence of the alarm; and showing the alarm occurrence. And an alarm notification means for transmitting the alarm notification data to the terminal unit.

The alarm registration means sets at least an alarm name, an alarm class, an alarm generation node, an alarm generation condition, an alarm registration state, an alarm notification data specification, and an alarm display processing content as an alarm registration item, and the alarm display is performed. The means is characterized by setting at least an alarm name, an alarm class, an alarm occurrence node, an alarm occurrence time, and an alarm display process as parameters for specifying an alarm to be displayed.

[0007]

The network monitoring system with the user-definable alarm processing function of the present invention has the following features.

(A) User-definable alarm processing Only alarms specified by the user are inspected by the user-definable alarm registration means at the time of message reception in the main body, and the alarm occurrence is detected when the alarm occurrence condition is satisfied. To be done. When an alarm is detected, the alarm notification data is transferred from the main unit to the terminal unit, and the alarm display unit performs alarm display processing by inputting the alarm notification data by the alarm display unit. As a result, the alarm occurrence is transmitted to the user. The point that only the alarm specified by the user is detected is significantly different from the conventional one.

(B) Alarm generation condition In order to generate an alarm when it is truly necessary, the alarm registration means specifies the alarm generation condition. The generation conditions consist of the following items. Message type: Specify the message that causes the alarm. Usually, the message type can be identified by the message number, and checking is very easy. It may be the designation of multiple message types. Message content: A specification description of the conditions that the content of the message should satisfy. For example, do not specify this without analyzing the message content, perform the description processing in the program and interpret and execute the program in the main body to check the message content, specify some of the check processing prepared in advance in the main body, etc. Can be considered. It is necessary that the time required for the check process does not burden the main body. Message monitoring period: Specify the period for monitoring messages. It is assumed that only the messages received within the period are involved in the alarm generation. Message occurrence frequency: An alarm occurs if a message satisfying the occurrence condition is received more than a specified number of times within the unit observation period. Alarm registration status: Specify whether or not the registered alarm is detected. It is used to temporarily handle the alarm registered by the parameter in the same way as the unregistered state.

(C) Alarm Registration Items for Alarm Selection The following alarm registration items are used to select the alarms displayed in the alarm display. Alarm name: Specify a name to identify the alarm. Alarm class: Designation of the class to which the alarm belongs. While the message class was fixed, the user can specify a class for each alarm, so that a class structure convenient for the user can be created. Alarm occurrence node: Specify the node where the alarm occurred.

(D) Alarm registration items related to alarm display processing Alarm notification data specifications: Specification of data and specifications to be notified when the main body unit notifies the terminal unit of an alarm occurrence.
There are usually multiple messages related to alarm occurrence, and what specifies the notification data among them is specified.For example, only the last message, all messages related to alarm occurrence, only certain parameter part in the message, etc. Conceivable. It is desirable to have an efficient specification that does not take time to transfer the alarm notification data. Alarm display process content: When the main unit notifies the terminal unit of an alarm occurrence, the description of the alarm display process that is activated in the terminal unit by inputting the alarm notification data. For example, the display process is always fixed and this specification is not specified, the description is made by a program, the alarm display is performed by interpreting and executing the program at the terminal unit, some of the alarm display processes prepared in advance at the terminal are specified, etc. Can be considered. Since the alarm display process is realized by the program of the terminal unit, processes other than the alarm display can actually be performed. The following are examples of alarm display processing. Alarm notification, that is, ringing of an alarm bell for recognizing an abnormal state of the network, control operation such as state transition (discoloration, blinking) of a node or node configuration diagram in the network diagram shown on the terminal screen, event Automatic issuing of control commands to devices involved in the occurrence.

(E) Display alarm selection item The items for selecting an alarm to be displayed on the alarm display mechanism include the following items in addition to the designation of the alarm name, alarm class, and alarm generation node. Alarm occurrence time: Period (from what hour to what minute)
Is specified, and only alarms that occurred within that period are displayed.

The terminal unit 7 notifies the network state and causes the user to perform a corresponding process.

The main body section 6 has an alarm detection section 12 and an alarm notification section 13, and each time the main body section 6 receives the message 4, the alarm detection section 12 checks the alarm generation condition registered in the alarm registration table 10. However, when the alarm generation condition is satisfied, the alarm notification unit 13 notifies the terminal unit 7 of the generation of the corresponding alarm in the form of alarm notification data 14.

The terminal unit 7 has an alarm registration unit 8. The user uses the alarm registration unit 8 to register the alarm definition 9 as a unit of network monitoring. The alarm registration unit 8 decomposes the specifications of the registered alarm definition 9, registers the designation for detecting the alarm occurrence in the alarm registration table 10 of the main body unit 6, and designates the alarm display processing by the alarm display of the terminal unit 7. Register in the process registration table 11. Further, the terminal unit 7 has an alarm display unit 15, and when an alarm notified from the main body unit 6 is received, it corresponds to the generated alarm in the alarm display processing registered in the alarm display processing registration table 11. Is activated with the alarm notification data 14 as an input.

Various methods can be considered for designating the alarm display processing, but a basic library operation related to network monitoring prepared as a system library is combined to provide a program capable of defining a more complicated procedure. It is possible. In the alarm display processing, in addition to executing the terminal screen control procedure for the alarm display 16,
It includes execution of procedures for issuing node control commands for the node control 17.

FIG. 2 is a diagram showing an example of a user interface screen of the alarm registration section in FIG. Alarm registration items will be described with reference to FIG. (The alarm occurrence frequency display 22 indicates how often the registered alarm is currently occurring and is not directly related to the registration.) The alarm registration item 21 defines the alarm occurrence condition, It can be divided into items that become selection items of display alarms at the time of alarm display and items related to alarm display processing.

Items that can be selected as display alarms are an alarm name (Alarm Name), an alarm class (Alarm Class), and an alarm generation node (Office Name).

Message type (in this example, a single type of message is a message number (Message Number)) is used to define the alarm generation condition.
), The message occurrence frequency (in this example, the observation period (Period) and the threshold value of the number of times a message occurs during the period (Threshold)), and whether the registered alarm is to be detected. There is a specified alarm registration status (Alarm Status),
In addition to these, there are a message content specification that describes the condition that the content of the message should satisfy when an alarm occurs, and a message monitoring time that specifies a time zone in which the message occurs.

As related to the alarm display processing, the alarm display processing content designation (in this example, the processing procedure name (Callbac executed in the terminal when an alarm occurs)
(k Name) specification) and other than this, there is an alarm notification data specification for notifying the terminal unit from the main body unit.
