  The present invention relates to a network communication state monitoring device capable of monitoring a connection state of a network and easily identifying a cause by easily finding a cause when a connection to a predetermined network or a connection terminal cannot be made and notifying a user. Is.

  Conventionally, a network monitoring terminal has been provided to constantly monitor the communication status with other communication devices on the network, and in the event of a failure, refer to the pre-categorized failure factors and pre-register the occurrence factors from the failure information that has occurred In general, it is specified from the factor list obtained (see, for example, Patent Document 1).

  FIG. 8 is a block diagram showing a general configuration of a conventional network communication state monitoring apparatus.

  In FIG. 8, a network monitoring terminal 801 is connected to a network and monitors the communication state of a partner terminal 809 to be monitored. The network monitoring terminal 801 executes the network monitoring program 802 and controls the communication unit 803 that monitors the connection state of the network. Communication information of the communication unit 803 is input to the communication monitoring unit 804 as communication packet information, and the communication monitoring unit 804 constantly monitors the communication state. The monitoring result is input to the abnormality detection unit 805. The abnormality detection unit 805 monitors the communication state of the partner terminal 809 existing on the network. If a communication abnormality occurs, the disconnection or error data is displayed.

Display means.

  Further, the failure factor automatic detection means includes resource information classification means for classifying the type of resource information of the communication terminal, communication device analysis means for acquiring communication device related information of the communication terminal and analyzing an operation state, and the communication terminal A connection state detection unit that monitors communication state and connection state of the device and detects failure occurrence information such as disconnection, resource information classified by the resource information classification unit, and communication device related information analyzed by the communication device analysis unit, The acquired information list generating means for generating a list acquired as a cause of failure from the communication information, the disconnection determining means for determining that a failure has occurred from the communication information detected by the connection state detecting means, and the disconnection determining means And a switch unit for registering the acquired information list of the acquired information list generating unit in the storage unit based on the cut information. It is.

  The present invention automatically determines the current operating state from the setting information of the wireless terminal to be used or the information of the communication device, lists up information that may cause a failure, and lists when a communication failure occurs. By notifying the user of the failure factor list that has been uploaded, there is no need to pre-register the failure factor, and there is no need to have an external monitoring management terminal. It becomes possible to shorten the time.

  In addition, if you save the created failure factor list and notify the user of the failure factor with higher priority based on the difference from the previous failure factor list saved at the next startup, the failure factor can be identified in a shorter time. become.

  If the failure factor solution technique is stored, the failure factor can be automatically resolved without notifying the user when the failure occurs.
