The vCenter Server Appliance provides a composite health indicator that enables you to test a single value that represents the health of all the appliance components. This procedure shows how to test the composite health indicator.
The value of the overall system health indicator reflects the strongest trouble indication among the appliance components. If any component has a red indicator, the overall system health indicator is red, else if any component has an orange indicator, the overall system health indicator is orange, and so on.
A gray value for any component indicates that data for the subsystem is unknown. If one or more components have a gray value, but all other subsystems are green, then the overall system health indicator is gray rather than green. However, if any component has a definite trouble indication, the overall system health indicator reflects the strongest trouble indication among the components.
Verify that you have an active authenticated session with the vCenter Server Appliance. This procedure assumes that the session ID is present in the security context of a stub configuration.
