The management middleware 105c also supports a drawing processing function of displaying the autonomous notification information received from the managed device 20 using the device icons representing the managed devices 20. Hereinafter, the autonomous notification drawing processing function using this device icon will be described.

FIG. 7 shows an example of a display screen of a drawing application "IPMaP" supported by the management middleware 105c. This "IPMaP"
Displays, for example, the managed devices 20a, 20b, and 20c in the communication network system as shown in FIG. 1 as device symbols 71, each of which is iconified, and receives the autonomous device received from each managed device 20. The processing for changing and displaying the color of the device symbol 71 corresponding to the transmission source managed device 20 in accordance with the information indicating the system failure state in the notification information (see FIGS. 5 and 6) is performed. In FIG. 7, the Hino center device corresponds to, for example, the managed device 20a in FIG. Similarly, in FIG. 7, Toyota remote device 1 and Toyota remote device 2
Respectively correspond to the managed devices 20b and 20c in FIG. Device symbol 7 arranged in “IPMaP”
Regarding the operation of the device status color 1, for example, it is possible to set green for a normal range, yellow for a warning zone, and red for a danger zone.

Next, a description will be given, with reference to a flowchart shown in FIG. 8, of an operation of operating the device symbol color on the "IPMaP". To realize the device symbol color operation, first, an initialization setting process is performed (step 801), and then a trap event callback registration process is performed (step 802). That is, in the initialization setting process, the trap (autonomous notification) process is started by the process start from the management middleware 105c, and the API (Applic
Initialization of the connection state between these two (OVwIni
Perform t). In the trap event callback registration process, a trap event callback is registered (OVsnmpEventOpen) to receive a trap (callback call) from the management middleware 105c.

After the above processing is completed, in the "IPMaP", the state analysis processing of the apparatus symbol 71 is performed upon receiving a trap from the managed apparatus 20 through the management protocol 105d (step 811) (step 811). 803). Specifically, the source I of the notified trap
The current failure state of the trap transmission source device symbol 71 is read from the P address, compared with the notified system state of the trap, and analyzed for any change.

In this analysis, if there is no change in the state, the monitoring of the occurrence of a trap is continued (step 811).
If there is a change in the state, a device symbol color change process is performed (step 804). In this device symbol color change process, only when a change is detected in the device symbol status analysis process in step 803, the color of the trap transmission source device symbol 71 is changed according to the system failure received by the trap (OVwSetStatusOnSymbol). I do. FIG.
9 is a table showing the relationship between the system failure state received by the trap and the color of the trap transmission source device symbol changed from the status of the trap transmission source device symbol 71. FIG.

As described above, according to the network management apparatus 10 of the present invention, not only the occurrence of a failure in the managed device 20 but also the recovery of the failure,
Since the change is displayed as the color change of the device symbol 71 representing 0, the administrator can recognize both the occurrence and the recovery of the failure of the managed device 20 in a timely manner. Further, the display by the device symbol 71 is displayed on the management middleware 10.
By combining this with the autonomous notification history display by 5c, it is possible to realize a configuration that can determine the occurrence or recovery of a past failure.

The network management device 10 of the present invention
Has a configuration / status display function of displaying information related to the configuration and status of the managed device 20 in addition to the autonomous notification display function described above. The configuration referred to here is, for example, the managed device 2

The screen display application 105b is responsible for processing related to the configuration / status display function.

The configuration / status display processing operation of the managed device 20 in the network management device 10 will be described below. The configuration / status display processing in the screen display application 105b in the network management apparatus 10 is as follows.
For example, it can be activated in response to a predetermined configuration / state confirmation operation from the input unit 103. As an example of the configuration / state confirmation operation, the administrator may specify the IP address of the managed device 20 to be confirmed on the input unit 103, and then perform an operation to instruct the display process to be activated. In addition, for example, on the “IPMap” screen in FIG. 7, with the device symbol 71 corresponding to a certain managed device 20 displayed in color indicating that a failure has occurred, the managed device 2
It is also possible to perform an operation of clicking in the area of the device symbol 71 corresponding to 0, and to activate the display function in response to this operation.

After the start operation described above, the screen display application 105b uses the management middleware 105c and the management protocol 105d to display information relating to the above-described configuration and state of the managed device 20 connected via the communication path 30. Managed middleware 204 of the managed device 20

In the managed device 20 to which this request is sent,
A request from the screen display application 105b is received using the management protocol 204d, and the request is passed to the managed middleware 204c. The managed middleware 204 receives the request, and the storage
4 reads the configuration / state management information 204b (information reflecting the external connection slot structure, the operation state of the internal board, the state of the power supply, the state of alarm occurrence, and the like in the apparatus), and manages the information 204b. Network management device 1 using protocol 204d
A response process for sending to 0 is performed.

On the other hand, the network management device 10 uses the management protocol 105d to
The configuration / state management information 204b transmitted as a response from 0
And the information 204b is stored in the management middleware 105c.
To be stored. Further, the screen display application 105b
Is the above-mentioned configuration stored in the management middleware 105c.
A drawing process is performed on the display unit 104 based on the state management information 204b. In this drawing processing, the screen display application 105b draws an image related to the configuration and state corresponding to each item in the configuration / state management information 204b acquired from the managed device 20, as it is, as an actual device image of the managed device 20. .

Generally, in the managed device 20 (real machine), an interface slot or the like is provided on the front surface of the housing, and the operation state of the internal board connected to the interface slot or the like, the power supply state, the alarm occurrence state, and the like are determined. A display element or the like for displaying is provided. The actual device image means an image content that can be recognized in the same manner as when the front surface of the housing of the managed device 20 (actual device) is actually seen.

After the network management device 10 draws the configuration and state of the managed device 20 in the actual device image as described above, the network management device 10 periodically performs the configuration / state management of the managed device 20 by the same processing. The information 204c is obtained. On the other hand, the managed device 20 responds to a periodic information acquisition request from the network management device 10 in response to the status monitoring unit 2.
The configuration / state management information 204c reflecting the latest contents is returned based on the monitoring result of No. 03. The screen display application 105b updates the past contents with the latest contents using the configuration / state management information information 204c acquired periodically, and continues drawing with the actual device image. As a result, even if the configuration or state of the managed device 20 changes, the latest configuration and state of the managed device 20 are always drawn as an actual device image. Accordingly, the administrator can actually update the latest configuration and state of the managed device 20 to the managed device 2.
It is possible to recognize exactly the same as when the user goes to 0 and looks at the front of the housing, and the maintenance and management work of the managed device 20 can proceed smoothly.

Next, a specific example of a drawn image related to the configuration and state of the managed device 20 in the network management device 10 will be described. 10 and 11 show display examples of the configuration and status of the managed device 20 in the network management device 10, respectively.
