filename

Specifies the initial trace file to be read. filename is nvarchar(256), with no default.

number_files

Specifies the number of rollover files to be read. This number includes the initial file specified in filename. number_files is an int.

If number_files is specified as default, fn_trace_gettable reads all rollover files until it reaches the end of the trace. fn_trace_gettable returns a table with all the columns valid for the specified trace. For more information, see sp_trace_setevent (Transact-SQL).

This function can read a trace that is still active on the instance on which it is executed.

Requires ALTER TRACE permission on the server.
