In this post, I am sharing a SQL DBA Script for getting the definition of default trace of SQL Server.

Why is this important?

When you are running multiple traces on your SQL Server while troubleshooting particular event, you should know the definition of the particular trace which helps you in the better investigation.

Using fn_trace_geteventinfo, you can get the trace definition.

Get the default trace_id of instance:

SELECT distinct traceid 
FROM ::fn_trace_getinfo(default)
GO

traceid
-----------
1

Pass trace_id in fn_trace_geteventinfo() and get the definition of Trace:

select
	tg.eventid as EventID
	,te.Name as EventName 
	,tg.columnid as ColumnID
	,cols. name as ColumnName
from :: fn_trace_geteventinfo (1) as tg 
INNER JOIN sys.trace_events as te 
	ON tg.eventid = te.trace_event_id
INNER JOIN sys.trace_columns cols 
	ON tg.columnid = cols.trace_column_id
