serviceNamespace

The service namespace for an Amazon Web Services service. Provide the service namespace to learn when the IAM entity last attempted to access the specified service.

To learn the service namespace for a service, see Actions, resources, and condition keys for Amazon Web Services services in the IAM User Guide. Choose the name of the service to view details for that service. In the first paragraph, find the service prefix. For example, (service prefix: a4b). For more information about service namespaces, see Amazon Web Services service namespaces in the Amazon Web Services General Reference.
