Privileges needed to run SQL Server Profiler without sysadmin privileges

 

In starting with SQL Server 2005 and above a SQL Server user or login does not need to have SYSADMIN privileges to use the SQL Server Profiler.

It can be accomplished by,

GRANT ALTER TRACE to [Login]

BOL explanation:

By default, running SQL Server Profiler requires the same user permissions as the Transact-SQL stored procedures that are used to create traces. To run SQL Server Profiler, users must be granted the ALTER TRACE permission
