Event Log Record Fields

edit

Contains data from a Windows event log record.

activity_id

edit

type: keyword

required: False

A globally unique identifier that identifies the current activity. The events that are published with this identifier are part of the same activity.

computer_name

edit

type: keyword

required: True

The name of the computer that generated the record. When using Windows event forwarding, this name can differ from the beat.hostname.

event_data

edit

type: object

required: False

The event-specific data. This field is mutually exclusive with user_data. If you are capturing event data on versions prior to Windows Vista, the parameters in event_data are named param1, param2, and so on, because event log parameters are unnamed in earlier versions of Windows.

event_id

edit

type: long

required: True

The event identifier. The value is specific to the source of the event.

keywords

edit

type: keyword

required: False

The keywords are used to classify an event.

log_name

edit

type: keyword

required: True

The name of the event log from which this record was read. This value is one of the names from the event_logs collection in the configuration.

level

edit

type: keyword

required: False

The level of the event. There are five levels of events that can be logged: Success, Information, Warning, Error, Audit Success, and Audit Failure.

message

edit

type: text

required: False

The message from the event log record.

message_error

edit

type: keyword

required: False

The error that occurred while reading and formatting the message from the log.

record_number

edit

type: keyword

required: True

The record number of the event log record. The first record written to an event log is record number 1, and other records are numbered sequentially. If the record number reaches the maximum value (2³² for the Event Logging API and 2⁶⁴ for the Windows Event Log API), the next record number will be 0.

related_activity_id

edit

type: keyword

required: False

A globally unique identifier that identifies the activity to which control was transferred to. The related events would then have this identifier as their activity_id identifier.

opcode

edit

type: keyword

required: False

The opcode defined in the event. Task and opcode are typically used to identify the location in the application from where the event was logged.

provider_guid

edit

type: keyword

required: False

A globally unique identifier that identifies the provider that logged the event.

process_id

edit

type: long

required: False

The process_id identifies the process that generated the event.

source_name

edit

type: keyword

required: True

The source of the event log record (the application or service that logged the record).

task

edit

type: keyword

required: False

The task defined in the event. Task and opcode are typically used to identify the location in the application from where the event was logged. The category used by the Event Logging API (on pre Windows Vista operating systems) is written to this field.

thread_id

edit

type: long

required: False

The thread_id identifies the thread that generated the event.

user_data

edit

type: object

required: False

The event specific data. This field is mutually exclusive with event_data.

user.identifier

edit

type: keyword

example: S-1-5-21-3541430928-2051711210-1391384369-1001

required: False

The Windows security identifier (SID) of the account associated with this event.

If Winlogbeat cannot resolve the SID to a name, then the user.name, user.domain, and user.type fields will be omitted from the event. If you discover Winlogbeat not resolving SIDs, review the log for clues as to what the problem may be.

user.name

edit

type: keyword

required: False

The name of the account associated with this event.

user.domain

edit

type: keyword

required: False

The domain that the account associated with this event is a member of.

user.type

edit

type: keyword

required: False

The type of account associated with this event.

version

edit

type: long

required: False

The version number of the event’s definition.

xml

edit

type: text

required: False

The raw XML representation of the event obtained from Windows. This field is only available on operating systems supporting the Windows Event Log API (Microsoft Windows Vista and newer). This field is not included by default and must be enabled by setting include_xml: true as a configuration option for an individual event log.

The XML representation of the event is useful for troubleshooting purposes. The data in the fields reported by Winlogbeat can be compared to the data in the XML to diagnose problems.
