Event Code event_code String The Event ID or Code that the product uses to describe the event.
Schema Extension extension Schema Extension[] The schema extension used to create the event.

Schema Extensions extensions Schema Extension[] The schema extensions used to create the event.
Labels labels String[]

The list of category labels attached to the event or specific attributes. Labels are user defined tags or aliases added at normalization time.

For example: ["network", "connection.ip:destination", "device.ip:source"]
Log Level log_level String The audit level at which an event was generated.
Log Name log_name String The event log name. For example, syslog file name or Windows logging subsystem: Security.
Log Provider log_provider String The logging provider or logging service that logged the event. For example, Microsoft-Windows-Security-Auditing.
Log Version log_version String The event log schema version that specifies the format of the original event. For example syslog version or Cisco Log Schema Version.

Loggers loggers Logger[] An array of Logger objects that describe the devices and logging products between the event source and its eventual destination. Note, this attribute can be used when there is a complex end-to-end path of event flow.
Modified Time modified_time Timestamp The time when the event was last modified or enriched.
Original Time original_time String The original event time as reported by the event source. For example, the time in the original format from system event log such as Syslog on Unix/Linux and the System event file on Windows. Omit if event is generated instead of collected via logs.
