vCenter Server 7.x
When vCenter Server boots, the health status of certain services changes from an initial state to a healthy state.
If, in the alarm rule for “Health status changed alarm”, the “Trigger the alarm and” setting is changed to “Show as Critical”, the corresponding alarm will be triggered.
In the alarm rule for “Health status changed alarm”, change the “Trigger the alarm and” setting to the default value, “Keep the target’s current state.”
