  In the fault detection technology for network connection according to the prior art, the fault monitoring device determines that the message source is a faulty device, and displays a fault. For example, a client computer via a hub goes down, When a hub detects it, it is determined that a failure has occurred in the hub, and thus there is a problem that the system administrator cannot easily identify which connected device has a failure.

  An object of the present invention is to eliminate the above-mentioned problems caused by the prior art, and to provide a fault message processing method and fault message processing system that can easily identify a network device in which a fault has occurred.

  In order to achieve the above object, the present invention provides a fault message processing method in a network in which a plurality of network devices and network monitoring devices are connected, wherein the network monitoring device includes an interface number assigned to a network device and the interface. An error message character string or error message corresponding to the message ID from the network device when a message ID and / or error message character string is received from the network device that has detected the failure, and has a conversion table with the IP address corresponding to the number A first feature is that an interface number included in a character string is extracted, and an IP address corresponding to the extracted interface number is obtained using the conversion table.

  Furthermore, the present invention is a failure message processing system in a network to which a plurality of network devices and network monitoring devices are connected, and a plurality of message IDs and / or error message character strings corresponding to the failure are transmitted when a failure is detected. A network device and a network monitoring device, wherein the network monitoring device converts an interface number assigned to the network device and an IP address corresponding to the interface number, and an error message character corresponding to the message ID An error message storage unit that stores a column, and when a message ID is received from a network device that has detected a failure, an error message character string or network corresponding to the message ID received from the error message storage unit Extract the interface number included in the error message character string received from the device, the second feature to obtain the IP address corresponding to the interface number and the extracted using the conversion table.

  The failure message processing method and the failure message processing system according to the present invention provide an error corresponding to a message ID when the failure monitoring apparatus receives a message ID and / or error message character string included in a message from a network device that detects the failure. By extracting the interface number included in the message character string or error message character string and obtaining the IP address corresponding to the extracted interface number using the conversion table, the device in which the failure has occurred can be easily identified. .

  Hereinafter, a failure message processing method and a failure message processing system according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a network system to which a failure message processing method and a failure message processing system according to the present embodiment are applied, FIG. 2 is a diagram illustrating a flowchart for explaining failure message processing according to the present embodiment, and FIG. It is a figure which shows an example of a conversion table at the time of the failure message process by this embodiment.

  As shown in FIG. 1, the network to which the present embodiment is applied includes a plurality of network devices 100 (only one is shown in the figure) and a monitoring program for monitoring the network device 100. When the network device 110 detects that the specific function is not functioning normally by the monitoring program, the network device 110 is configured to report the abnormality. The network device 110 may be included in the function of the network monitoring device 120.

  The network device 100 has a function of sending a message ID corresponding to an error message corresponding to the abnormality to the network or a function of sending the error message itself to the network when an abnormality is detected by itself. Anomaly detection is reported to the network device 110 by sending its own IP address over the network.

  When the network device 110 receives the message ID via the network, the network device 110 converts the error message together with the IP address of the device that detected the failure into a character string of the error message and sends it to the network monitoring device 120. A function for sending, and a function for sending the error message to the network monitoring device 120 together with the IP address of the device that detected the failure when the error message character string itself is received.

  The network monitoring device 120 performs conversion for identifying a failed device from the received message using a message receiving unit 121 that receives the message from the network device 110 and a conversion table 123 described later. A message source information conversion unit 122 and a faulty device display unit 124 that displays an IP address of the faulty device identified by the source information conversion unit 122 to the administrator.

  For example, as shown in FIG. 3, the conversion table 123 corresponds to the IP address 301 of the device in which the failure is detected and the character string 302 of the error message. ) 303 is stored. Specifically, for example, when the network device 100 is a switching hub in which a plurality of clients are connected to a plurality of ports, and the client connected to the port 1 goes down, the network device 100 (hub) Connects to port 1 (interface 1) of the network device 100 (hub) in response to messages such as its own IP address (172, 21, 119, 10) and error message string "Interface 1 does not respond to agent interface" The IP address of the client that has been registered is “172, 21, 119, 123”. In the example of FIG. 3, the IP address of the client connected to port 2 (interface 2) of the network device 100 (hub) is “172, 21, 119, 124”.

  In the network system configured in this way, as shown in FIG. 2, the network device 110 detects the occurrence of a failure, and sends the IP address of the network device 100 that has detected this failure and the character string of the error message to the network monitoring device 120. Then, the network monitoring apparatus 120 accepts the message (step 202) in a state where the contents of the conversion table 123 have been read in advance (step 201), and whether the sender information 301 exists in the conversion table 123. (Step 203). If it is determined that the message exists in step 203, it is determined whether a part of the message (for example, “Interface 1”) exists in the conversion table (step 204). In step 204, the corresponding conversion data If there is no data, the steps 203 to 204 are repeated for all the column data of the conversion table 123 (step 205). If there is a part of the corresponding message in the step 204, the character string 302 of the message is displayed. Is used as a key to convert the IP address 303 that is the transmission source information of the failed device (step 206), and the IP address is sent to the failed device display unit 124 (step 207). For example, in the example of FIG. 3, when an error message character string “the interface of the agent is not responding at interface 1” is input from the source of the IP address “172, 21, 19, 10”, the “interface 1 ”Is extracted, and the IP address“ 172, 21, 19, 123 ”of the machine in which the failure corresponding to this character string has occurred is transmitted.

  In step 204, if the source information of the received message is not in the conversion table 123 or does not partially match the specified character string even if it exists in the conversion table 123, the message as it is is displayed as the faulty device display unit 124. By displaying the sender information that is the IP address on the faulty device display unit 124, for example, it can be identified that a fault has occurred in the detection device itself.

  Therefore, according to the present embodiment, when the monitoring device 120 receives the message ID and / or error message character string included in the message from the network device that detected the failure, the error message character string or error message corresponding to the message ID is received. By extracting the interface number included in the character string and obtaining the IP address 303 corresponding to the extracted interface number using the conversion table, the device in which the failure has occurred can be easily identified.
