field

A field in a CloudTrail event record on which to filter events to be logged. For event data stores for CloudTrail Insights events, Config configuration items, Audit Manager evidence, or events outside of Amazon Web Services, the field is used only for selecting events as filtering is not supported.

For more information, see AdvancedFieldSelector in the CloudTrail API Reference.

Selectors don't support the use of wildcards like * . To match multiple values with a single condition, you may use StartsWith, EndsWith, NotStartsWith, or NotEndsWith to explicitly match the beginning or end of the event field.
