WHAT TO EXPECT
The Topology Graph gives users a visualization of their cloudSwXtch network, highlighting the data flowing between the various components. This includes cloudSwXtches, swXtchBridges, and the endpoints (with and without xNICs). With a wealth of different filtering tools, users have complete flexibility on how they monitor and configure their data.
In this article, users will learn how to navigate to the topology graph in wXcked Eye and also an intro on the various panels.
The Topology Graph page is split into multiple page’s , this page is organized into the following functions:
Locating the wXcked Eye Topology Graph page
To navigate to the Topology Graph page, users will need to click on the menu (≡) option at the top left-hand corner by the swXtch.io logo.

From there, select Topology Graph.
Topology Graph Layout
The Topology Graph can be organized into four points of interest. To start, the main topology graph, at the center, displays traffic traveling to and from one or more the cloudSwXtch(s). Then, there are two configuration panels: The View By/Filter Bar and the Laters Toolbox. Both are collapsible. Finally, on the left of the page, there are some additional tools, such as Center Graph, Resize Nodes, Remove Groups Config, Glossary, and Settings.
Below shows the Tools expanded:
From left to right: Close expansion, Center Graph, Resize Nodes, Remove Groups Config, Glossary and Settings.
Center Graph - will center the graph in the window. If there are nodes currently outside the window the center will take that into account and they will then be shown.
Resize Nodes - will auto-scale each node only if it's too small for the amount of Sockets around it.
Remove Groups - will remove any groups the user has created, it will not remove groups that are set in the settings for auto-group.
Glossary - will bring up a glossary of terms.
Settings: Will bring up settings for the graph.
Min pps to show a stream link: Some communications that are multicast are systems talking to one another as opposed to user intended multicast. Typically these are very small, to reduce traffic in the graph this setting will eliminate any traffic that is just noise.
Min stream links to auto group: For ease of use this setting will automatically group streams going into or out of a node if it hits this threshold. Note that the tool “Remove Groups” above will not ungroup streams that are within this threshold.
Component Information Panel
In addition to these four main areas, selecting a component node in the topology graph will open its Component Information Panel. Here, users will find metrics specific to that component and additional specific information, such as Environmental and Hardware data. Selecting a component with a right click opens the Radial Menu for configuration options. Depending on the component class (cloudSwXtch, bridge, or xNIC), this could include adding adaptors for protocol fanout via the cloudSwXtch component node, configuring HA at the xNIC level, and toggling deduplication on or off for the endpoints. Note that most of this configuration can also be accomplished via System Management.
For information on specifics for each component and the options refer to the Component Information Panel article.
Moving and collapsing tool boxes
The Layers Toolbox and Other Tool boxes are all collapsible. Floating windws cand be moved.
Statistics Explained
Each cloudSwXtch component (cloudSwXtch, cloudSwXtch Bridge, and xNIC) acts as a probe point, illustrating the following metrics:
TX
RX
Out of Order (OoO)
Missing Packets
These values will display when the Statistics layer is toggled on.
Resize and Edit Components in Topology Graph and adding Tags
The components can be resized and edited in the Topology graph by left mouse click to bring up the options.
Select the plus or minus button to make the component larger or smaller in the graph. In the case below it has been selected to the largest size, therefore the plus button is greyed out.
Select the edit button to rename or to add tags to a component.
Grouping and Highlighting Streams
Grouped streams
Streams can be grouped into components that have stream links between them. In most cases, this will be a cloudSwXtch and a VM with an xNIC installed. In this example, the streams will be grouped between a cloudSwXtch and an XNIC.
Below is an example before the stream links are grouped between the cloudSwXtch and the xNIC.
Group Streams
To group the streams click on one of the streams in the set and select “Group stream links”.
Below is after the selection:
View Grouped Stream Links
By selecting the “+” button, users can see the details of the streams within the linked multicast groups.
Result:
Ungroup Streams
By selecting the “ungroup” button, the data for the streams is no longer grouped.
Result:
Highlight Stream
To see where a particular stream is used select the “Highlight the Stream” icon.
To Highlight a stream:
The result is below, now the stream is highlighted everywhere it is consumed or produced:
To remove the highlight click anywhere in the Topology Graph.
