sys.traces (Transact-SQL)

The sys.traces catalog view contains the current running traces on the system. This view is intended as a replacement for the fn_trace_getinfo function.

For a complete list of supported trace events, see SQL Server Event Class Reference.

Important

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use Extended Event catalog views instead.
