Viewing Devices in Graphics and Details View (Map View Frame)

Click the Devices tab in Net Inspector header to display the Devices page (as shown in the figure below).

By default, the Devices page contains two frames:

The Map View frame provides two views:

Both views also provide information about the current status of devices and active alarms, as described in the Information Provided by Icons on Maps topic.

The Explorer panel in the left portion of the Map View frame displays the Net Inspector user view structure. A user view can have a hierarchical tree-like structure of (sub)maps. Maps contain zero or more devices, submaps, and graphic elements (lines, connections, rectangles, bitmaps, etc.). Click a (sub)map in the Explorer, to view its contents in the main section of the Map View frame. Explorer panel also provides a quick overview of device statuses by propagating the color of the most severe device status up the hierarchical tree to the root map. 

This section describes the principle of monitoring active alarms and object statuses in the Map View frame.

 

Graphics View

The Graphics view displays the contents of maps in a graphical manner, by showing device and submap icons, and optionally, graphic elements (lines, connections, rectangles, bitmaps, etc.). It also provides information about the current status of devices and active alarms, as described in the Information Provided by Icons on Maps topic.

 

  1. To enable the Graphics view, select the Graphics entry from the toolbar drop-down menu.

  1. To view the contents of the map in full screen mode, click the Full screen mode button (). This command displays the contents of the map spread across the entire screen. In full screen mode, you can still use your mouse to zoom and pan the map view. To exit the full screen mode, press the ESC key or click a device name hyperlink.

  2. To view the device performance statistics for a device, click the device name hyperlink below the relevant device icon to open the Device Performance Page in a new tab in web browser.

  3. To view or edit the device properties (e.g., name, address, class, polling profile access profile, etc.) and device monitoring options (interfaces, storage units, processes, services), select the device icon on the map and click the Edit button ()  in the toolbar. This opens the Edit Device Monitoring Options dialog box. You can select more than one device on the map by holding down the CTRL button while clicking device icons or by making a selection with the mouse (click and drag the mouse cursor to select a map area) and then click the Edit Device button to edit specific properties of all selected devices at the same time (e.g., polling profile, access profile, polling engine).

  1. To disable monitoring of one or more devices, select the device(s) on the map (by holding down the CTRL button while clicking device icons or by  making a selection with the mouse) and click the Stop monitoring button () in the toolbar.

  2. To enable monitoring of one or more devices, select the device(s) on the map (by holding down the CTRL button while clicking device icons or by making a selection with the mouse) and click the Start monitoring button () in the toolbar.

  3. To make other changes to the map (e.g., reposition devices, add devices, remove devices, add text, images, connections, etc.), you need to switch into the map Configuration mode by clicking the Configure button () in the upper-right section of the Devices frame.

 

Viewing Link Status and Utilization

In the Graphics view you can view the current link status (up or down) and traffic information (interface in/out bitrate and utilization).

The width of a connection line automatically increases with increasing connection data throughput (the higher bitrate, the thicker the line) and its color automatically changes with increasing link utilization (black – low utilization, brown – moderate utilization, orange – medium utilization, dark red – high utilization). If a link is down, the color of the connection line is pure red.

The link status, bitrate and utilization is shown only for connections between objects that support SNMP MIB-II Interfaces table and for which the endpoint interfaces are known. Connection endpoint interfaces and labels can be configured in the Connection Labels dialog box.

Details View

 

The Details view of a map displays information about devices and (sub)maps in form of a table. It also provides information about the current status of devices and active alarms associated with devices on the current map, as described below.

 

  1. To enable the Details view, select the Details entry from the Map View frame drop-down menu.

  1. The Details view displays a list of all devices and submaps on the selected map. The following columns let you monitor the status of and active alarms on the listed devices (see also Information Provided by Icons on Maps topic):

Displays the current status of the device. In case of a submap, this field displays the most critical status of the devices(s) included in the submap.

Displays the total number of active alarms on the device or the total number of active alarms on all devices in the submap (in case of a submap). This field reflects the color of the most severe active alarm that currently exists on the device (see alarm severity colors). In case of a submap, this field reflects color that matches the color of the most severe alarm that exists on the objects within the given submap branch.

Displays the number of new alarms on the device or the number of new alarms on all objects in the submap (in case of a submap). “New” alarms are active alarms, which are not acknowledged. The New Alarms field reflects the color of the most severe new alarm that currently exists on the device (see alarm severity colors). In case of a submap, this field reflects color that matches the color of the most severe new alarm that exists on the objects within the given submap branch.

  1. To display or hide individual columns in the Map View frame - Details view , click the  column selector displayed in Map View toolbar and check or uncheck the columns you want to display or hide, respectively.

  2. To sort the list of devices by a particular column, click the relevant column header (Name, Address, Status, etc.). For example, to sort listed devices by their status, click the Status column header.

  3. To view the device performance statistics for a device, click the device name hyperlink in the Name column to open the respective Device Performance Page.

  4. To quickly find the devices of interest, use quick filters. All columns in the map details view have quick filter fields below the header row. Enter the desired text phrase into the respective quick filter filed (or select the desired entry for a quick filter drop-down list) to filter the list and display only the matching devices. For example, to find devices, whose name contains string "serv", type this string into the Name quick filter field. You can use two or more quick filter fields to achieve the desired filtering effect (combined filter criteria). Note that quick filters are short-lived, i.e., they are automatically removed when the page/frame is reloaded. For more details about using quick filters, please refer to the Managing Active Alarms topic.

  5. To view or edit the device properties (e.g., name, address, class, polling profile access profile, etc.) and device monitoring options (interfaces, storage units, processes, services), select the corresponding device by checking the checkbox in the first column in the map details view and click the Edit Device button ()  in the toolbar. This opens the Edit Device Monitoring Options dialog box. You can select more than one device  and then click the Edit Device button to edit specific properties of all selected devices at the same time (e.g., polling profile, access profile, polling engine).

  6. To disable monitoring of one or more devices, select the device(s) on the map (by checking their checkboxes in the first column) and click the Stop monitoring button () in the toolbar.

  7. To enable monitoring of one or more devices, select the device(s) on the map (by checking their checkboxes in the first column) and click the Start monitoring button () in the toolbar.
