Is also present. When such an information file is monitored, an operation on the highly confidential information file can be accurately monitored by specifying the information file in the file specification mode and executing the linked display.

  From a different point of view, when grasping the operation status of the communication terminal C operated by a user who is inexperienced, the user to be managed by specifying the terminal in the terminal specification mode and executing the associated display The operation at the communication terminal C operated by can be accurately managed.

[Another embodiment]
The present invention may be configured as follows in addition to the embodiment described above.

(A) Of the operation screens G displayed in the operation screen display area 40A of the management screen 40, a display target is selected (designated) with the cursor Cu, and then the association display button 43 is selected and operated. Thus, the processing form may be set so that the display in the file designation mode is performed without displaying the designation dialog 50.

  The processing mode in this file designation mode is shown in the flowchart of FIG. That is, when the link display button 43 is operated after the selection of the operation screen G, the connection information acquisition unit 25 creates an information file on the file server D based on the operation log stored in the operation log storage unit 23. Processing for acquiring the terminal identification information of the communication terminal C in the connected state (being connected) and the file name to which the communication terminal C is connected (the same processing as the first processing form in the management display output), Alternatively, a process of acquiring terminal identification information of the communication terminal C connected to the information file of the information storage unit 37 of the file server D from the connection information storage unit 38 (a process similar to the second processing form in the management display output). Perform (Step # 201).

  Next, the display mode is set to the file designation mode, and the association setting means 26 sets the information file designated in the designation dialog 50 and the communication terminal C determined by the connection information as a display target (# 202). Step) After that, as in the case shown in FIG. 9, the association image generation means 28 displays the file image F corresponding to the information file on the association display screen 60, and at the communication terminal C connected thereto, The operation screen G as the corresponding terminal display information is displayed, and the line image S is displayed at the position connecting them to perform the association (step # 203). Such display is continued until the association display for the linking display screen 60 is reset (step # 204).

  By setting such a display form, the trouble of inputting information in the designation dialog 50 is saved, and an information file connected to the communication terminal C to be monitored is immediately displayed to realize efficient monitoring.

(B) As shown in FIG. 13A, an icon X (an example of file display information) of a folder including an information file and an operation screen G of the communication terminal C are displayed in association with each other by a line image S. By selecting the icon X with the cursor Cu (for example, double-clicking), as shown in FIG. 13B, the file image F (an example of file display information) of the information file included in the folder and the corresponding communication terminal The operation screen G of C is displayed in association with the line image S. By adopting a display form capable of hierarchical display in this way, the display on the association display screen 60 can be simplified, and the information such as the directory of the information file can be easily grasped.

(C) As shown in FIG. 14, the file image F of the information file and the operation screen G are displayed on the association display screen 60, and the file image F and the operation screen G that are in the connected state are connected. When the line image S is displayed and there are many communication terminals C connected to the information file, the operation screen G corresponding to the communication terminal C is displayed in an area that can be displayed outside the link display screen 60. The display mode is set so that the line image S is displayed between them. That is, since the operation screen G is information displayed on the monitor 8 of the communication terminal C, an appropriate display area is necessary for grasping the contents. For this reason, the association display is realized without degrading the monitoring function by effectively using the vacant space of the management monitor 5 for the information file to which many communication terminals C are connected.

(D) As an association display that associates the file image F (file display information) of the information file with the operation screen G (terminal display information) of the communication terminal C, as shown in FIG. (File display information) and the operation screen G (terminal display information) of the communication terminal C are displayed in a region image S surrounding the screen, or displayed so as to be connected with a wide belt-like image. Various display forms can be adopted as long as they are in the association state.

(E) As shown in FIG. 16A, the file image F (file display information) of the information file is displayed on the file display screen 65, and the operation screen G (terminal display information) of the communication terminal C is displayed on the terminal display screen. A line image S is displayed which associates the file image F and the operation screen G in the connected state with each other. The line image S displayed in this way is displayed across the file display screen 65 and the terminal display screen 66. Further, as shown in FIG. 16B, when displaying a line image S that associates a file image F and an operation screen G that are in a connected state, a lower portion of a display frame E that displays the operation screen G. The file name of the information file in the connected state is displayed on the information display unit Ea. By displaying the file name in this manner, for example, the scroll bar 65A of the file display screen 65 or the scroll bar 66A of the terminal display screen 66 is operated, so that the corresponding item is not displayed on the screen. It will be able to grasp that.

(F) When one communication terminal C is connected to a plurality of information files, the line image S associated with the file image F of the information file in the active state is displayed darker than the line image S in the inactive state. Or display thickly (the line image S may be hidden in the inactive state). In this case, the inactive line image S may be deleted. By changing the display form in this manner, the management monitor 5 can effectively manage and monitor the terminal. In this embodiment, the line image S has been described as an example of the association display. However, even if the line image S is different, the active state is deactivated by changing the density or thickness when displaying the line image S. The same effect can be achieved by displaying the state.

(G) For example, when displaying the operation screen G for the linked display as shown in FIG. 4, FIG. 9, or FIG. 10, the size of the operation screen G is displayed larger as the display time is longer. . By changing the size in this way, it is possible to grasp the long connection time from the size of the operation screen.

(H) For example, when the file image F is displayed for the linked display as shown in FIG. 4, FIG. 9, or FIG. 10, the larger the number of communication terminals C connected to the information file is. Display large or display at a high position (upper side on the monitor). By setting the display form in this way, the number of connections of the communication terminal C to the information file can be visually grasped from the display form of the file image F.

In the present invention, the file display information may be set as display information corresponding to the information file, or may be set as display information corresponding to a folder including the information file. According to this, the display information of the information file or the image of the folder including the information file can be associated.

  In the present invention, the connection information acquisition means connects from the file server connected to the communication network to the terminal identification information of the communication terminal connected to the information file stored in the file server, and the communication terminal is connected. File information including the file name of the existing information file may be acquired. According to this, when acquiring the terminal identification information of the communication terminal connected to the information file of the file server, the terminal identification information of the communication terminal connected to the information file by accessing the file server and the file name are Since the file information can be acquired, the file name of the information file and the identification information of the communication terminal connected to the information file can be acquired and display by the association display means can be realized without acquiring the operation log.
