General information associated with a UDM event.
| JSON representation | 
|---|
| { "id" : string , "productLogId" : string , "eventTimestamp" : string , "eventTimestampAttributes" : [ enum ( | 
| Fields | |
|---|---|
| id |   ID of the UDM event. Can be used for raw and normalized event retrieval. A base64-encoded string. | 
| productLogId |   A vendor-specific event identifier to uniquely identify the event (e.g. a GUID). | 
| eventTimestamp |   The GMT timestamp when the event was generated. Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:  | 
| eventTimestampAttributes[] |   Attributes associated with eventTimestamp. This field is used to distinguish between different types of timestamps that can be used to represent the eventTimestamp. | 
| collectedTimestamp |   The GMT timestamp when the event was collected by the vendor's local collection infrastructure. Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:  | 
| ingestedTimestamp |   The GMT timestamp when the event was ingested (received) by Chronicle. Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:  | 
| eventType |   The event type. If an event has multiple possible types, this specifies the most specific type. | 
| vendorName |   The name of the product vendor. | 
| productName |   The name of the product. | 
| productVersion |   The version of the product. | 
| productEventType |   A short, descriptive, human-readable, product-specific event name or type (e.g. "Scanned X", "User account created", "process_start"). | 
| productDeploymentId |   The deployment identifier assigned by the vendor for a product deployment. | 
| description |   A human-readable unparsable description of the event. | 
| urlBackToProduct |   A URL that takes the user to the source product console for this event. | 
| ingestionLabels[] |   User-configured ingestion metadata labels. | 
| tags |   Tags added by Chronicle after an event is parsed. It is an error to populate this field from within a parser. | 
| enrichmentState |   The enrichment state. | 
| logType |   The string value of log type. | 
| baseLabels |   Data access labels on the base event. | 
| enrichmentLabels |   Data access labels from all the contextual events used to enrich the base event. | 
| structuredFields |   Flattened fields extracted from the log. | 
| parserVersion |   The version of the parser that generated this UDM event. | 
Tags
Tags are event metadata which is set by examining event contents post-parsing. For example, a UDM event may be assigned a tenantId based on certain customer-defined parameters.
| JSON representation | 
|---|
| { "tenantId" : [ string ] , "dataTapConfigName" : [ string ] } | 
| Fields | |
|---|---|
| tenantId[] |   A list of subtenant ids that this event belongs to. A base64-encoded string. | 
| dataTapConfigName[] |   A list of sink name values defined in DataTap configurations. |
