SQL profiler is a graphical user interface (GUI) software tool in Microsoft’s SQL Server relational database management system (RDBMS). It monitors, analyzes, troubleshoots and tunes SQL databases and their environment.
Database monitoring, which, arguably, is the most widely-used and important RDBMS function, is performed by generating customized monitoring instances of specific database portions, also known as trace logs.
This term is also known as SQL Server profiler.
SQL Profiler may be used to capture data for real-time or future review. In addition, traces may be scheduled to run at specific times. For example, to compare performance when the database is busy or idle, one trace may be set up to run in the morning at 10 a.m. when the database is busiest, and another set up to run at 2 a.m. when there is little or no database activity.
