This documentation refers to a previously released version of BMC Discovery.
See the information on this topic for the latest version (11.2) or version 11.1.

With the BMC Discovery 11.0 release, the software context view is now extended to cover infrastructure. The infrastructure view replaces the previously existing dependency visualizations. There are two types of view:

  • The Visualize - Software view focuses on software and communication between items of software and shows some details of the hosts and load balancers involved.
  • The Visualize - Infrastructure view focuses on the connectivity to network and storage components. It shows the switches a host is connected to, underlying storage for host filesystems, VMs on VM servers, or if the given host is a VM, the server on which it is hosted.

The Software and Infrastructure visualizations are supported for modern, standards-compliant web browsers only. The view works best in recent versions of Google Chrome and Mozilla Firefox, and it is also supported for Microsoft Internet Explorer version 10 and later. It is not supported for Internet Explorer 9 or earlier.

Launching Software and Infrastructure Visualizations

When you view either a single node or multiple node groups, a Visualize button is shown.

  1. When viewing any node, or selected nodes on a list page, click Visualize. The Visualize window is displayed showing details on the selected node, and the hardware and software it is communicating with. If you select multiple nodes from a list view, those nodes are shown along with the hardware and software they are communicating with.
    The image below shows the software context popup view for a Software Component.

    Make the visualization large by clicking the + in the top right corner.

    Make the visualization occupy the full browser window by clicking the maximize icon in the top right corner. Exit full window mode by clicking the minimize icon in the top right corner
  2. To change the view, click Focus > Infrastructure in the side bar. 
    The infrastructure visualization preview is displayed. You can hide, create, or delete collections by using the modelling controls. The image below displays the infrastructure view.
  3. You can manipulate the image using the tools provided. For more information, see the visualizations tool set.

 

When viewing a large visualization, remember that it is still part of the node view page. Information which may be useful while working on a model is available by scrolling down. In full window mode, only the visualization is displayed, so you must exit full window mode using the minimize button. The Application Model Editor always occupies the full window; click Stop Editing to leave the editor.

Visualizations tools set

The following table lists the options you can use to manipulate a visualization and perform modeling tasks.

When you have saved the model, you can also export a model definition. Exported model definitions can be imported using the Model > Applications page.

Icon Description

Drag and select modes

Toggles the mode in which the visualization can be displayed.

In both docked (maximized) and floating (minimized) views, use the mouse scroll wheel to zoom in and out, and drag on the background to move around. On a touch device, pinch to zoom. Double-click inside the view to recenter and zoom the display to fit the window.

  
Drag mode
Drag the background to move the whole diagram. Drag individual icons to rearrange the view.
 
Select mode
  • Click a node to select it alone. Previously selected nodes are deselected.
  • Shift-click a node to add it to previously selected nodes.
  • Control-click a node to deselect an icon where multiple icons are selected.
  • Click the background and drag around nodes to lasso-select a group of nodes.
  • Hold Shift while dragging the background to add to the current selection with a lasso-select.
  • Hold Control while dragging the background to remove from the current selection with a lasso-select.

Focus
Enables you to change between the Visualize - Software view and the Visualize - Infrastructure view.
 
Software

In the Visualize - Software view, the node that represents the object you are looking at is highlighted. The Visualize - Software view focuses on software and communication between items of software and shows some details of the hosts and load balancers involved.

From the Visualize - Software view, you can begin application modeling.

Click a node to view the object page of that node.

 
Infrastructure

In the Visualize - Infrastructure view, the node that represents the object you are looking at is highlighted. The Visualize - Infrastructure view focuses on the connectivity to network and storage components. It shows the switches a host is connected to, underlying storage for host filesystems, VMs on VM servers, or if the given host is a VM, the server on which it is hosted.

You must change to the Visualize - Software view to begin application modeling. When you are modeling an application, the Focus control is disabled to ensure you remain in the Visualize - Software view.


Layout

Displays the ways in which the object nodes can be arranged. Once a layout has been calculated, you can further manipulate the view by dragging nodes, and by expanding and collapsing collections. Choosing the same layout again recalculates the layout, and can lead to a clearer view.

The following options are available under Layout:

 
Switch wide/tall
Choose a wide or tall layout depending on the shape of the nodes you have selected.
 Manual Groups and Model Definition

Provides options for viewing information node membership of manual groups and model definitions. Click the Groups icon Manual groups next to the help icon in the top right to see a key to reconcile labels, indicators and groups.

 

Do not show
Do not show any group or model definition labels or indicators.  
 

Show indicators
Show indicators. Indicators are small color-coded shapes next to the node icon, a different colored one for each group.  Click the Groups icon to see a key to colors and group membership.
 

Show labels
 Show labels, colored labels containing the group name.
 LayoutProvides options for laying out the nodes. Experimenting with the layouts can reveal structure in the model.
 
Force-directed
Spreads nodes using a balance of attracting and repelling forces.

 


Impact
Shows impacting nodes at lower levels on the view than impacted nodes. For example, a host container impacts a contained host, which impacts a software instance. Arrows on the view show the direction of impact.
 
Root at top
Arranges nodes into a tree view with a root node at the top.
 
Application layers
Arranges the view into the functional layers of the application. Hosts are in a layer at the bottom of the visualization, and user access points, such as load balancers at the top of the visualization.
 

Relationship routing

Provides graphical options for routing the relationships between nodes.
 
Direct
Gently curved lines link nodes. The nodes are arranged for clarity, subject to the selected layout.
 
Orthogonal
Lines link nodes using horizontal and vertical section joined by right angle curves.
 
Avoid nodes
Straight lines link nodes where possible. The lines are curved to avoid crossing nodes.

Choose the node kinds to show. Select the node kinds to show or hide from the list of node kinds shown in the model. Depending on the application that you are modeling, you may see the structure more clearly by hiding certain nodes such as hosts.

You cannot hide Collections. Rather, when all node kinds held in a collection are hidden, the collection itself is no longer displayed.

You can export or print the current view for review at any stage. The images are produced without the associated tools and menus.

When you have saved the model you can export it as a model definition

 


Print Visualization

To print an image of the current view, click Print Visualization and select a paper size from the drop-down list. The browser print dialog is displayed. You must choose the same paper size in the print dialog.

 

 

Export as SVG

To export an SVG image of the current view, click Export and choose SVG.
 
Export as PNG

To export a PNG image of the current view, click Export and choose PNG.

 
Export Model Definition

When you have saved the model, you can also export a model definition. Exported model definitions can be imported using the Model > Applications page.

Provides a list of removed nodes. You can restore any of the removed nodes to the view by clicking the Restore button.

Opens the current view in the application modeling editor. You can choose to:

  • Start a new model.
  • Add to an existing model.

This option is only enabled in the Visualize - Software view.
