creation_unix_timestamp

Records the creation time of a resource as a unix timestamp.

deletion_unix_timestamp

Indicates the deletion time of a resource as a Unix timestamp. If not provided, the resource is considered running.

id

A unique identifier for the tracked resource.

kind

Specifies the kind of the tracked resource.

time_unit
