Fields

• date :: Maybe POSIX

  The date and time when the event occurred.

newEvent :: Event

Create a value of Event with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:date:Event', event_date - The date and time when the event occurred.

$sel:message:Event', event_message - A user-defined message associated with the event.

$sel:sourceName:Event', event_sourceName - The source of the event. For example, if the event occurred at the node level, the source would be the node ID.

$sel:sourceType:Event', event_sourceType - Specifies the origin of this event - a cluster, a parameter group, a node ID, etc.

event_date :: Lens' Event (Maybe UTCTime)

The date and time when the event occurred.

event_message :: Lens' Event (Maybe Text)

A user-defined message associated with the event.

event_sourceName :: Lens' Event (Maybe Text)

The source of the event. For example, if the event occurred at the node level, the source would be the node ID.

event_sourceType :: Lens' Event (Maybe SourceType)

Specifies the origin of this event - a cluster, a parameter group, a node ID, etc.
