It generally denotes some state change in the system.

Events have a limited retention time and triggers and messages may evolve with time. 
Event consumers should not rely on the timing of an event with a given reason reflecting a consistent underlying trigger, 
or the continued existence of events with that reason. 


Events should be treated as informative, best-effort, supplemental data.

In Kubernetes, [auditing](/docs/tasks/debug-application-cluster/audit/) generates a different kind of
Event record (API group `audit.k8s.io`).
