Notes
With the TraceFile object you can:
Read from a trace log file.
Write to a trace log file.
In addition to the Trace and Replay objects, the trace log file can be accessed manually with Guide de référence du Générateur de profils SQL Server or using a set of Transact-SQL stored procedures called Présentation de SQL Trace.
