Configuring the Service Graph

This section describes how to operate on the service graph using the CORD GUI.

Adding Information to the Graph

By default, the GUI renders only the Services in the service graph, but you can augment the available information by pressing:

  • Shift + f toggle fullscreen mode
  • Shift + s to add ServiceInstances to the graph
  • Shift + i to add Instances to the graph (this requires ServiceInstances to be shown)
  • Shift + n to add Networks to the graph (this require Instances to be shown)

Defining the Position of Services in the Graph

XOS defines a model called ServiceGraphConstraint that lets you enforce constraints on the nodes position in the display. The following describes the basics of how this works.

Setting the Services on a Line

["a", "b", "c"]

will position the nodes as:

a -> b -> c

Services as a Tree

["a", ["b", "c"]]

will position the nodes as:


Empty Spots in the Graph

[[null, "a"], ["b", "c"]]

will position the nodes as:

 a -> c

Note: All the nodes not defined in the ServiceGraphConstraint model will float around.

Events Monitored by the Service Graph

  • will render the graph again
  • will listen for changes in the state machine
