How to Use SQL Server Profiler and Tuning Advisor

What is SQL Server Profiler

Microsoft SQL Server Profiler is a graphical user interface to SQL Trace for monitoring an instance of the Database Engine or Analysis Services. You can capture and save data about each event to a file or table to analyze later. For example, you can monitor a production environment to see which Stored Procedures are affecting performance by executing too slowly.

What is Tuning Advisor

Tuning advisor helps to get the performance report that is generated by SQL Profiler and provide the appropriate indexing. It takes one or more SQL statements as input and invokes the Automatic Tuning Optimizer to perform SQL tuning on the statements.

Real Time Example

The following is a real time example:

  • First of all start SQL Server 2008
  • Click on New Query
  • Select Northwind database

Let’s fire some select statements.

Now let’s start SQL Profiler, go to the tools.


You will see it is shows the trace properties, like name, provider name and provider type.

You will see that there are many queries running internally but we want only the Northwind report. Let’s make some changes in the trace properties.

Since we are creating this for tuning puposes, select the template for tuning and select the event selection tab and click the “Column filters” button.
