  • Page 8 Using MegaVision as a plug-in application for standard NMS platforms. Working under HP OV NNM UNIX MegaVision-WEB GUI can be accessed from any standard NMS platform. Please, review the following notes for HP OV NNM UNIX as an example how to organize such interface.
  • Page 9 Optional. You may perform step b. for any supported device located on the HP OV map. In this case you can receive MegaVision-WEB GUI without looking for the MegaVision-WEB PC Icon first.

  • Page 10: Logging In

    Logging In When you start MegaVision, you can log in as user or supervisor. As a user, you can view network configuration and device status, but you cannot make any changes in the network. As a supervisor, you can view network configuration and device status, and change configurations and parameters of network devices.
  • Page 11 “Using Passwords” section in this chapter. To Login as a User The following directions describe how to login for the first time you enter MegaVision as USER. After this initial login procedure, you can set up a new password for USER mode, or set up the Password window to bypass the Login window.

  • Page 12: Using Passwords

    Using Passwords In its default configuration, MegaVision requires a password to login. You can also set up the Password window to start the program without a password.. To Change Password Settings As A User Or Supervisor 1. From the Options menu, choose Password. The Password dialog box opens.

  • Page 13: Main Window

    Main Window The MegaVision main window is the major gateway to all monitoring and control functions of devices on your network. The main window contains the map/submap - the graphical representation of your network. Each device that has been correctly added to the map appears as an icon with its device name.
  • Page 14 (e.g. see “Paris” icon on Figure 3.) If a device is colored gray, MegaVision does not have any information about it (it is currently being polled). Devices are gray immediately after MegaVision is loaded, or just after you have added it to the map.

  • Page 15: Adding Background Images

    You may add a background image to the main map by selecting Select Background Image from the Map menu item. Some bitmaps are included with MegaVision, or you may specify your own bitmap (only the .bmp format is supported). Use Images editing programs (like MS Windows “Paint”) to create/edit bitmaps.

  • Page 16: Device Main Window

    Device Main Window Each device on the MegaVision map has a main window that displays the front panel of that device. From this panel you can quickly monitor the device’s operations in real time. LEDs on the port image buttons indicate activity, collisions, and flow control for each port on the device.

  • Page 17: Control Windows

    Control Windows The Device Main Window provides access to a set of Control Windows, through which the Network Manager can perform remote control operations on the managed devices, change the device parameters. Although control windows come in a variety of layouts and perform different functions, most have a common set of features as can be seen in the following Port Configuration window.

  • Page 18: Graphics Support

    Graphics Support You can graphically view counters data as speedometer, line, or bar graphs. These alternate views of data make it easier to analyze and compare statistics at a glance. A tiling option allows you to neatly line up several graphic windows on the screen. Statistics in any window that contains the Graphics image can be viewed as a graph.
  • Page 19 Speedometers This type of display shows the instantaneous value of a selected counter in a speedometer- like window. The window contains a moving indicator, the counter category, and the current value. This view is most helpful during situations such as excessive collisions, where you need to adjust system parameters to improve traffic flow.
  • Page 20 Line Graphs The line graph feature provides a wide variety of options for monitoring and comparing data. In its simplest form, one graph for each counter is displayed in separate windows showing current activity. When you open a line graph window, the selected counter’s activity is dynamically recorded in one polling interval increments on the graph.
  • Page 21 in a new window. Figure 11b. Multiple Line Graphs. For some statistic-to-graph conversions, you will need to use the multiply coefficients to properly scale graph lines, especially when you use two counter categories, where values might have large differences. By entering a multiply coefficient for a counter, its current graph value is multiplied by the coefficient.

  • Page 22: Polling Interval

    Figure 12. Graph Options Dialog. 1. Polling Interval Changes the value for the Lines graph main window and its parent (see figure 8.) 2. Min Y, Max Y, Min t, Max t axis. If you check Automatic Change of Ranges, changes are made automatically. NOTE: For graphs, where the X-axis indicates time, the X check box should be always checked.
  • Page 23 In addition to Line and Speedometer Graphs, MegaVision also supports bar graphs. You can display data from any counter with bars. You can add data from a counter to an existing bar graph (default), or generate a new graph Use bar graphs for comparing the relative amounts of two or more values.

  • Page 24: Alarms

    Alarms Alarms are activated by status changes in network devices. When MegaVision detects a change in a device, it generates an alarm. A beep is sounded and the alarm is recorded in the Alarm Log, indicating the date and time, the device in which it occurred, the severity, and a short description of the reason for the alarm.
  • Page 25 Only alarms received after the configuration will adhere to the new settings. Please note that when the Generic radio button is selected the configuration changes apply to all MegaVision devices. In order to see/configure specific alarms for the current device type (if any) select the Specific radio button.
  • Page 26 Clicking the OK button will send the message. Please note that this feature may be also useful if you want to send a brief e-mail message to somebody and the access to the Send E- mail window is provided via MegaVision-WEB remote GUI interface.
  • Page 27 Figure 19. Remote MegaVision-WEB GUI interface.

  • Page 28: Snmp Mib Browser

    SNMP Management Information Base (MIB) Browser MegaVision provides an SNMP MIB browser. From the Main Window menu Control item, select MIBView. You can carry out any SNMP operation on the value of an object from any MIB listed in the MIB files list. Select a device from the Devices list and a MIB from the MIB files list.
  • Page 29 Add, Remove, Change, and Compile buttons are used to add new MIBs to the MibView window. It is recommended to place the MIB file in the application’s MIBS directory. Important: There is no guarantee that new MIBs will be compiled properly. That is why those users, who want to use this feature, must have ability to analyze the output errors and understand ASN1 language.

  • Page 30: Interfaces Monitoring

    Interfaces Monitoring MegaVision provides extensive monitoring performance of any SNMP devices interfaces, whether they belong to the supported set of devices or not. Interfaces monitoring may be accessed through the Monitor menu item on the main menu bar. The various options will be described below.
  • Page 31 Operational Status of the Interface (up/down/testing) – the current operational state of the interface. The testing state indicates that no operational packets can be passed. Double click on the desired interface line or click on the Statistics and Graphs per Interface button to open Interfaces Statistics (per interface) window (described immediately after this section, figure 22.) This action will display performance information about this particular interface.
  • Page 32 The information is based on the ifTab (RFC1213, MIB-II). The counters are described there as follows: Input Bytes - the total number of octets received on the interface, including framing characters. Input Unicast Packets - the number of subnetwork-unicast packets delivered to a higher-layer protocol.
  • Page 33 Figure 23. Statistics and Graphs per Counter window Interfaces Utilization Window. You may enter this window from: 1. The Main Menu Bar (under Monitor) 2. The Utilization button in the Interfaces Table window 3. From the device window menu bar of certain devices.
  • Page 34 Figure 24. Interfaces Utilization window The buttons at the bottom of the graphs have the same function as those in the line graphs window. This window shows the interface’s utilization in percent (right bar graphs) and the interface’s errors per second (left trend graph). The information is based on device Interface Table (ifTable from MIB-II, RFC1213).

  • Page 35: Rmon Support

    RMON Support MegaVision supports RMON Groups 1,2,3,9 for any RMON-capable device, which supports the same groups via SNMP. RMON Group 1 Statistics Window You can enter this window from: 1. The Main Window Menu Bar (under Monitor: RMON Group 1 Statistics) 2.
  • Page 36 This window shows the Control Table in the upper left corner. The table presents control entries for RMON Group 1. Each entry corresponds to one of the device’s interfaces. Usually this table contains entries for all of the interfaces on the monitored device.
  • Page 37 RMON Group 2 (History) Window You can enter this window from 1. The Main Window Menu Bar (Monitor: RMON Group 2) 2. From the device window menu bar for certain devices. Figure 30. RMON Group 2 Window. Information presented in the window includes: The History Control Table.
  • Page 38 Figure 31. Add RMON Group 2 Control Entry Window. You are required to enter some information, which describes how to collect statistics for reporting: 1. The desired Interface Number. 2. The Owner String to identify the entry owner (not required); Number of Buckets: the requested number of discrete time intervals over which data will be collected.
  • Page 39 When you open RMON Group 2 Window or select any History Control Table Entry, two Trend Graph Windows open (in addition to the main window) to reflect the History Table Information graphically: Interface Errors per interval (right window). Interface Utilization per interval in % (left window). While in the RMON Group 2 Window, you may jump to any other device without selecting it in the main map via the Device Name box (in the bottom right corner of Figure 30).
  • Page 40 interfaces, but may be empty as well (this is the default ). If this table is empty, it is due to one of the following reasons: RMON Group 3 is not supported on this device. RMON Group 3 is supported but there are no control threshold entries. You can create a threshold entry for any interface by clicking on the Create button.
  • Page 41 Rising Event Index: The Index from the Events Table (see below) which corresponds to Rising Event. Falling Event Index: The Index from the Events Table (see below), which corresponds to Falling Event. Start Up: The start-up alarm, i.e., conditions for an alarm to be sent as a result of the first sample.
