VersionN/A N/AThe version number of the event's definition.
Level<severity>String/Number/TextThe severity level defined in the event.
Task<vendorinfo>Text/StringThe task defined in the event. Task and Opcode are typically used to identify the location in the application from where the event was logged.
OpcodeN/A N/AThe opcode defined in the event. Task and Opcode are typically used to identify the location in the application from where the event was logged.
Keywords<result>Text/StringA bitmask of the keywords defined in the event. Keywords are used to classify types of events (for example, events associated with reading data).
TimeCreatedN/A N/AThe time stamp that identifies when the event was logged. The time stamp will include either the SystemTime attribute or the RawTime attribute.
EventRecordIDN/A N/AThe record number assigned to the event when it was logged.
CorrelationN/A N/AThe activity identifiers that consumers can use to group related events together.

  • Domain NETBIOS name example: CONTOSO
  • Lowercase full domain name: contoso.local\
  • Uppercase full domain name: CONTOSO.LOCAL
  • For some well-known security principals, such as LOCAL SERVICE or ANONYMOUS LOGON, the value of this field is NT AUTHORITY.
  • For local user accounts, this field will contain the name of the computer or device that this account belongs to.
SubjectLogonId<session>Text/StringA hexadecimal value that can help you correlate this event with recent events that might contain the same Logon ID.
PreviousTimeN/A Text/StringThe previous time in UTC time zone. The format is YYYY-MM-DDThh:mm:ss.nnnnnnnZ:
Y - years
M - months
D - days
T - the beginning of the time element, as specified in ISO 8601.
h - hours
m - minutes
s - seconds
n - fractional seconds
Z - the zone designator for the zero UTC offset. 09:30 UTC is therefore represented as 09:30Z. 14:45:15 UTC would be 14:45:15Z.
