Description

  The present invention relates to a work system that performs monitoring control of a communication device of a network.

  In a work device that performs network monitoring control, a graphical user interface (GUI) is used because of its operability. To briefly explain an example of GUI work, icons indicating network communication devices are displayed on the screen of the work device, and the maintenance person selects a control target device by selecting the icon. Further, when the selected control target device has a module configuration and has a plurality of individually controllable cards (modules), the work device issues a command to inquire about the mounted card to the control target device, and responds to the response. Based on this, the card mounted on the device to be controlled is graphically displayed. The work device displays a list of a series of commands that can be issued to the selected control target device or the selected control target card, and the maintenance person performs necessary control by selecting the command from the list.

  As described above, the application of the working device using the GUI needs information on the correspondence between the configuration of each communication device and the commands that can be issued. In addition, when a communication device is selected, a predetermined command is issued to the selected communication device in order to acquire information necessary for graphical display according to the configuration of the selected communication device. It is necessary to configure a work device application. However, the command to each communication device of the network differs for each device type (multiplexing device, cross-connect device, switching device, etc.) and for each vendor even for the same device type. Therefore, in order to monitor and control all communication devices in the network using the GUI, it is necessary to modify the application of the work device every time a new communication device is introduced into the network. Absent. Therefore, normally, in a network, a communication device that can be monitored (control of the status of alarms) and control using a GUI, a communication device that can be monitored using a GUI but cannot be controlled, and a communication device that cannot be monitored and controlled using a GUI Etc. will be mixed.

  Monitoring control for a communication device that cannot be monitored and / or controlled by this GUI is performed via a window (hereinafter referred to as a terminal window) on the display of the work device. This supervisory control interface by the terminal window is usually called a command line interface (CLI). An example of CLI work will be briefly explained. By specifying a control target device and opening a terminal window, the work device communicates with the control target device, and the control target device displays a character string for prompting command input in the terminal window. Display. Note that address information for communicating with the communication device, the name of the communication device, and the like are set in the work device in advance. The maintenance person inputs a character string corresponding to the command in the terminal window and presses the enter key or the like to issue the command to the control target device. The device to be controlled executes command processing and displays the response on the terminal window.

  In network monitoring control, when each communication device in the network issues an alarm, the maintenance person grasps the alarm content of each communication device, identifies the failure or problem location according to the alarm content of each communication device, A command for control is sent to each communication device of the network in order to recover the failure or to divert the traffic to the backup transmission path. The alarms issued by each communication device in the network, and the operation contents of each communication device corresponding to the alarm, for example, can be used to refer to the response method when a failure occurs or for other failures. Each case is stored as failure case data. Patent Document 1 discloses a configuration for generating a rule for determining a cause of a failure based on an event log. Patent Document 2 discloses a configuration for recording a GUI operation history.

  In an environment where GUI and CLI monitoring control coexist, in order to create failure case data that can be used later, the commands issued to the device via the CLI and GUI and the information indicating the responses to the commands are not sufficient. There is a need for information on what kind of command is issued to which device for what kind of screen display.

  The present invention provides a work system capable of creating failure case data that can be used later in an environment where monitoring control by GUI and CLI is mixed.

  According to one aspect of the present invention, there is provided a work system for monitoring and controlling a network by using a graphical user interface (GUI) and a command line interface (CLI), and a window for GUI and CLI is provided. A first history information is sent to the database means, including display means for displaying on the display, monitoring control information transmitted / received by the CLI between the communication devices of the network, and information of date / time when the monitoring control information is transmitted / received. When the display screen of the display is changed, the display screen after the change is captured, and the second history information including the screen data of the captured display screen and the changed date and time is transmitted to the database means. And a transmission means.

  In an environment in which monitoring control by GUI and CLI is mixed, it is possible to create failure case data that can be used later.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. In the following drawings, components that are not necessary for the description of the embodiments are omitted from the drawings.

  FIG. 1 is a configuration diagram of an entire system including a work system according to an embodiment. The work device 1 performs monitoring control of each communication device of the target network 6. The work device 1 can perform monitoring and control for some communication devices of the target network 6 using the GUI, but for other communication devices, one or both of monitoring and control can be performed using the GUI. This is not possible, and is configured to be performed by CLI. The work system according to the present embodiment includes a work device 1, a history database 2, a management device 3, and one or more terminals 4, all of which are connected to a management network 5. In addition, although the working apparatus 1, the history database 2, the management apparatus 3, and the terminal 4 will be described as different apparatuses, one or more of the working apparatus 1, the history database 2, the management apparatus 3, and the terminal 4 are set as one apparatus. You can also.

  FIG. 2 is an example of a display screen 50 displayed on the display by the work apparatus 1. In the example of FIG. 2, a terminal window 51 and a GUI window 52 are displayed on the display screen 50. For example, the terminal window 51 is communicating with a communication device named “Device1”, and the communication device returns a response “r1” to the command “c1” input by the maintenance person. It is shown that the communication device returns a response “r2” to the command “c2” input by the maintenance person. An area 521 of the GUI window 52 is an area for a search operation. For example, a search for a communication apparatus that can be operated by the GUI can be performed. Further, in the area 522 of the GUI window 52, communication devices to be controlled or monitored are displayed as icons. When the maintenance person selects the communication device displayed in the area 522 with a mouse or the like, a screen showing the device configuration is displayed. In the area 523 of the GUI screen 52, for example, an alarm issued from the communication device selected in the area 522 is displayed.

  FIG. 3A shows a communication sequence between the working device 1 related to the CLI and the history database 2, and FIG. 3B shows a communication sequence between the working device 1 related to the GUI and the history database 2. In the present embodiment, the work device 1 stores monitoring control information transmitted / received to / from the control target device in a log file as history information together with the date / time of transmission / reception in communication via the CLI. Note that the monitoring control information includes a command transmitted to the control target device, information received from the control target device as a response to the command, alarm information autonomously transmitted by the control target device, and the like. The log file is generated for each communication device, for example. The work device 1 periodically transmits log file difference information to the history database 2. Note that the history information including the monitoring control information and the date and time when the monitoring information is transmitted / received may be directly transmitted to the history database 2 without being stored as a log file in the work device 1.

  In the present embodiment, the work device 1 transmits, to the history database 2, history information including the monitoring control information transmitted / received to / from the control target device and the date / time when the monitoring control information was transmitted / received in communication via the GUI. Further, when the display screen displayed on the display of the work apparatus 1 is changed by GUI operation, the display screen after the change is captured, and the captured display screen data and history information including the date and time of change are transmitted to the history database 2. . Even if the maintenance person does not perform a GUI operation, even when the display screen is changed due to an alarm or the like issued by the communication device, the changed screen data and history information including the date and time of change are transmitted to the history database 2. . In the present embodiment, the screen to be captured is not only the GUI window 52 but the entire display of the work apparatus 1 including the terminal window. The monitoring control information transmitted / received by the GUI operation and the display screen data obtained by capturing the display screen may be temporarily stored in the work apparatus 1 and the difference may be periodically transmitted to the history database 2.

  FIG. 4 is an example of history information held in the history database 2. Note that FIG. 4 is a conceptual display and does not indicate how actual history information is stored. In FIG. 4, reference numeral 70 is history information of communication performed via the CLI with the communication apparatus named “Device1”, and reference numeral 71 is performed via the CLI with the communication apparatus named “Device2”. It is the history information of communication. Reference numeral 72 denotes history information of communication with each communication apparatus performed via the GUI. Reference numeral 73 denotes history information on the display screen.

  As shown in FIG. 4, the history database 2 stores each display screen displayed on the display of the work apparatus 1 and communication contents between the apparatus via the CLI and the GUI together with the date and time. For example, when a failure or the like occurs and recovery is performed by subsequent maintenance, failure case data is created by extracting history information from the occurrence to the recovery. In the present embodiment, when the management device 3 inputs the date and time of occurrence of failure (start date and time) and the date and time of failure recovery (end date and time) to the history database 2, the history database 2 stores the change date and time and the date and time of transmission and reception. Failure case data is created by extracting history information within the period from the start date to the end date. FIG. 5 is an example of failure case data. As shown in FIG. 5, the failure case data is data including a communication history by CLI and GLI with each communication device and a full screen displayed on the display of the work device 1 during the failure period.

  For example, all the operation contents including CLI can be grasped by displaying each display screen of a certain failure case data on the terminal 4 in the chronological order. However, the display screen contains information such as commands sent and received via the CLI and their responses, but these are stored as graphic data, not text data. It cannot be used for searching. In this embodiment, in order to have communication contents between the CLI and each communication device in the failure case data as text data, for example, the failure case data using a specific command or a specific response is received. You can quickly search for what you have done, making it easier to use as a reference for later failures. In this way, the terminal 4 displays the display screens of failure case data, for example, in chronological order, before and after using a specific command by CLI or GUI, and before and after receiving a specific response or alarm. It is possible to display a screen, or to search and display failure case data using a specific command. The same applies to the monitoring history information transmitted / received via the GUI.

  In the above embodiment, the display screen of the entire display of the work apparatus 1 including the terminal window 51 is captured. However, transmission and reception of the monitoring control information with the communication apparatus via the CLI and the GUI are stored as text data. Therefore, only the GUI window 52 can be used for capturing the display screen.

  The work system can be realized by a program that causes the computer to operate as the work device 1, the history database 2, the management device 3, and the terminal 4. At that time, for example, the working device 1, the history database 2, and the management device 3 can be realized on one computer. Further, the work device 1 can be realized as one computer, and the history database 2 and the management device 3 can be realized as one computer. Furthermore, each device can be realized on an individual computer.
