A health rule violation canceled warning event or a health rule violation canceled critical event is
generated when the health rule processor can no longer accurately assert that the health rule
violation continues to violate or that it has ended1. This can happen when the health rule is edited or
disabled, among other reasons1. Adding a new condition to the health rule or disabling the health
rule are two actions that would trigger a health rule violation canceled event, as they would change
the evaluation criteria or stop the evaluation altogether1. Marking the health rule as canceled or
removing the health rule from a policy are not valid actions, as they do not affect the health rule
configuration or status
