Event

Event is a report of an event somewhere in the cluster. 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.

Event

Field	Description
`action` string	action is what action was taken/failed regarding to the regarding object. It is machine-readable. This field cannot be empty for new Events and it can have at most 128 characters.
`apiVersion` string	APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
`deprecatedCount` integer	deprecatedCount is the deprecated field assuring backward compatibility with core.v1 Event type.
`deprecatedFirstTimestamp` Time	deprecatedFirstTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type.
`deprecatedLastTimestamp` Time	deprecatedLastTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type.
`deprecatedSource` EventSource	deprecatedSource is the deprecated field assuring backward compatibility with core.v1 Event type.
`eventTime` * MicroTime	eventTime is the time when this Event was first observed. It is required.
`kind` string	Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
`metadata` ObjectMeta	Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
`note` string	note is a human-readable description of the status of this operation. Maximal length of the note is 1kB, but libraries should be prepared to handle values up to 64kB.
`reason` string	reason is why the action was taken. It is human-readable. This field cannot be empty for new Events and it can have at most 128 characters.
`regarding` ObjectReference	regarding contains the object this Event is about. In most cases it's an Object reporting controller implements, e.g. ReplicaSetController implements ReplicaSets and this event is emitted because it acts on some changes in a ReplicaSet object.
`related` ObjectReference	related is the optional secondary object for more complex actions. E.g. when regarding object triggers a creation or deletion of related object.
`reportingController` string	reportingController is the name of the controller that emitted this Event, e.g. `kubernetes.io/kubelet`. This field cannot be empty for new Events.
`reportingInstance` string	reportingInstance is the ID of the controller instance, e.g. `kubelet-xyzf`. This field cannot be empty for new Events and it can have at most 128 characters.
`series` EventSeries	series is data about the Event series this event represents or nil if it's a singleton Event.
`type` string	type is the type of this event (Normal, Warning), new types could be added in the future. It is machine-readable. This field cannot be empty for new Events.

EventList

EventList is a list of Event objects.

Field	Description
`apiVersion` string	APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
`items` * Event array	items is a list of schema objects.
`kind` string	Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
`metadata` ListMeta	Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

EventSeries

EventSeries contain information on series of events, i.e. thing that was/is happening continuously for some time. How often to update the EventSeries is up to the event reporters. The default event reporter in "k8s.io/client-go/tools/events/event_broadcaster.go" shows how this struct is updated on heartbeats and can guide customized reporter implementations.

Field	Description
`count` * integer	count is the number of occurrences in this series up to the last heartbeat time.
`lastObservedTime` * MicroTime	lastObservedTime is the time when last Event from the series was seen before last heartbeat.
