The following table shows the attributes for the product event node.

Table: Attributes for the product event node

Name	Description
`dataCenter`	Optional. Specifies the data center of the event. If this attribute is not specified, GLOBAL is assumed. GLOBAL implies that the resource is without an assigned data center.
`endTime`	Optional. Specifies the time that the event ends. The format must be ISO 8601 format: yyyy-mm-ddThh:mm:ss.SSSZ (Z designates UTC). For an event of type EXIST, the `startTime` and `endTime` reflect the event duration for the resource instance. The end time is exclusive — that is, the event occurred up to, but not during the specified value. The end time must occur after the start time.
`environment`	Specifies the environment from which the message originated. If this attribute is not specified, PROD is assumed. This attribute is required for events of type USAGE_SNAPSHOT, but is optional for all other event types.
`eventTime`	Optional. Specifies the time of the event, using ISO 8601 format and UTC. Use this attribute instead of `startTime` and `endTime` in cases where the event does not have a range.
`id`	Required. Specifies the UUID for the event record. This value should be UUID version 1, 2, or 4. For more information, see RFC 4122.
`referenceId`	Optional. Specifies a GUID that identifies the event record that this record is updating. This attribute should be used if this event is correcting another event.
`region`	Specifies the region in which the event is located. If this attribute is not specified, GLOBAL is assumed. GLOBAL implies that the resource is without an assigned region.
`resourceId`	Specifies the ID of the resource. This attribute is required if the `resourceType` attribute is specified in the product node, but is optional otherwise.
`resourceName`	Optional. Specifies the customer-defined name of the resource.
`resourceURI`	Optional. Specifies a URI that uniquely identifies the resource.
`rootAction`	Optional. Specifies the action that caused the event.
`severity`	Optional. Specifies the severity of the event. Valid values are INFO, WARNING, and CRITICAL. This is attribute is valid only for system events, not for usage events.
`startTime`	Specifies the time that the event starts. The format must be ISO 8601 format: yyyy-mm-ddThh:mm:ss.SSSZ (Z designates UTC). The start time is inclusive, which means that the event occurred starting at the start time, not after. This attribute is required for events of type USAGE, but is optional for all other event types.
`tenantId`	Optional. Specifies the tenant Id of the feeds publisher
`type`	Required. Specifies the type of event. If one of the existing event types fails to produce any feeds, set this attribute to EXTENDED and add an `eventType` attribute to your product schema.
`version`	Required. Specifies the version of the event record.

Info
Cloud Feeds evaluates all product events against their XML schemas.

User access events in CADF

Cloud Feeds supports the Cloud Auditing Data Federation (CADF) standard. CADF provides a standard for the submission and retrieval of normative audit event data from cloud providers in the form of customized reports and logs.

For more information about CADF, see Cloud Auditing Data Federation.

Cloud Feeds defines a set of event types, which take different attributes.

The following examples show a user access event that is encoded as a CADF event. The CADF event is located inside the Atom content element.

User access events in Cloud Feeds

Cloud Feeds supports user access events, which use the CADF standard.
User access events provide a generic approach to capturing all API calls
that are issued against Rackspace product web services.

Cloud Feeds extends the CADF standard by providing a specific user
access event profile that captures audit data that is specific to the
user and the Rackspace cloud services they are using.

User access event data is included in the atom entry as a CADF
attachment of type auditData.
