Performing ML-based root cause isolation of an impacted service

Toggles the mode in which the visualization can be displayed.

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.

Enables you to change the following:

• Focus of the visualization
• Background shading to indicate locations and cloud regions
• Indicators and labels for model definitions and manual groups

Focus

Enables you to change between the Visualize - Software - Connected,  Visualize - Software, and the Visualize - Infrastructure views. In each view, the node that represents the object you are looking at is highlighted. Click a node to view its details panel.

Software - Connected

The Software-Connected view focuses on software and communication between items of software and shows some details of the hosts and load balancers involved.

Software

In the Software focus, the node that represents the object you are looking at is highlighted. The Software view focuses on software and communication between items of software running on a host, and is particularly useful for understanding what is running on a host.

Infrastructure

In the Infrastructure focus, the node that represents the object you are looking at is highlighted. The 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.

Show indicators. Indicators are small color-coded shapes next to the node icon, a different colored one for each group. Model definitions are shown as triangles; manual groups are shown as circles. Hover the mouse pointer over an indicator to see the name of the model definition or group.

 Show colored labels containing the group name.

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:

Layout

Provides 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

Root at top

Arranges nodes into a tree view with a root node at the top.

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.

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

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.

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

Undo/Redo

Enables you to undo or redo recent operations. Where no operation can be undone, the undo icon is disabled. Where no operation can be redone, the redo icon is disabled.

Using the keyboard, Control-Z is undo; Control-Y is redo.

When you save removal rules, the Undo/Redo queue is cleared.

Models and Groups

Provides information on any application models and manual groups to which nodes in the view belong. The Models and Groups icon is only displayed when show indicators or show labels is selected.

Key

Shows a key for the symbols used in views.

Zoom slider

Click + to zoom in and - to zoom out. Or drag the slider up or down respectively.

The mouse scroll-wheel can be used to zoom in and out.

To zoom using the keyboard, press '+' or '=' to zoom in, and '-' to zoom out.

Click the zoom to fit control to fit the image to the window.

Stop layout updates

Prevents any further layout updates. Sometimes with a large or complex model, the layout may take a long time to stabilize. Select this option to stop the updates.

Select all

Selects all nodes in the view.

Clear selection

Deselects all selected nodes.

Invert selection

Inverts the current selection. Nodes previously not selected are selected, and the reverse.

Undo action

For example, Undo extend model. If you have performed an action, undo it and return to the previous state. You can also use the Undo arrow at the top right of the visualization, or via the keyboard with Control-Z.

Redo action

If you have undone an action, redo it. You can also use the Redo arrow at the top right of the visualization, or via the keyboard with Control-Y.

Select node

Select a selected node. Available when right-clicking a node that is not selected.

Deselect node

Deselect a selected node. Available when right-clicking a selected node.

Add to selection

Add the node to the current selection. Available when right-clicking a node which is not currently selected.

Shows the impact flow into and from the selected node. Nodes whose outage would affect the selected node, and nodes that would be affected by an outage of the selected node are highlighted by dimming other connections. The arrows show the direction of impact. Also operates on multiple node selections (Show selection impact flow).

See Impact flow for an illustration of the use of the impact flow controls.

Show outgoing impacts /
Show selection outgoing impacts

Shows the impact flow from the selected node. Nodes that would be affected by an outage of the selected node are highlighted by dimming other connections. The arrows show the direction of impact. Also operates on multiple node selections (Show selection outgoing impacts).

Show incoming impacts /
Show selection incoming impacts

Shows the impact flow into the selected node. Nodes whose outage would affect the selected node are highlighted by dimming other connections. The arrows show the direction of impact. Also operates on multiple node selections (Show selection incoming impacts).

Keep only impact flow

The nodes and relationships that are not highlighted are discarded from the visualization.

Clear impact display

Clears the highlighting to show the rest of the visualization,

Expand collection

A collection is an automatically created group of closely related items. Expand collection expands the selected collection so that the individual nodes are visible in the view. The nodes from the expanded collection are highlighted. You can see what is contained in the collection using Preview collection.

Collapse back into collection

Collapses the nodes from an expanded collection back into the collection. Available when right-clicking a node that was expanded from a collection.

Hide highlighting of collection

Hides the highlighting of the named expanded collection.

Hide all highlighting

Hides all highlighting that shows the nodes from an expanded collection.

Remove link

Deletes the selected link. Available when you right-click a link between two nodes.
