keyAttributes

The attributes of the entity which identify the specific entity, as a list of key-value pairs. Entities with the same KeyAttributes are considered to be the same entity. For an entity to be valid, the KeyAttributes must exist and be formatted correctly.

There are five allowed attributes (key names): Type, ResourceType, Identifier, Name, and Environment.

For details about how to use the key attributes to specify an entity, see How to add related information to telemetry in the CloudWatch User Guide.
