Mapping with LogRhythm Schema

Device Key in Log Message	LogRhythm Schema	Data Type	Schema Description
Provider	N/A	N/A	Identifies the provider that logged the event. The Name and Guid attributes are included if the provider used an instrumentation manifest to define its events. The EventSourceName attribute is included if a legacy event provider (using the Event Logging API) logged the event.
EventID	<vmid> <tag1>	Number	The identifier that the provider used to identify the event.
Version	N/A	N/A	The version number of the event's definition.
Level	<severity>	String/Number/Text	The severity level defined in the event.
Task	<vendorinfo>	Text/String	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.
Opcode	N/A	N/A	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.
Keywords	<result>	Text/String	A bitmask of the keywords defined in the event. Keywords are used to classify types of events (for example, events associated with reading data).
TimeCreated	N/A	N/A	The time stamp that identifies when the event was logged. The time stamp will include either the SystemTime attribute or the RawTime attribute.
EventRecordID	N/A	N/A	The record number assigned to the event when it was logged.
Correlation	N/A	N/A	The activity identifiers that consumers can use to group related events together.
Execution	N/A	N/A	Contains information about the process and thread that logged the event.
Channel	N/A	N/A	The channel to which the event was logged.
Computer	<dname>	Text/String	The name of the computer on which the event occurred.
DestinationDRA	N/A	N/A	The destination directory replication agent distinguished name.
SourceDRA	N/A	N/A	The source directory replication agent distinguished name.
SourceAddr	N/A	Number	DNS record of the server from which information or an update was received.
NamingContext	N/A	Text/String	The naming context to replicate.
Options	N/A	Text/String	The decimal value of DRS Options.
StatusCode	<responsecode> <tag2>	Number	If there are no issues or errors, the status code will be 0. If an error happened, you will receive Failure event and Status Code will not be equal to 0.
