+
+
+<h2>Enabling and Disabling Profiler Sections</h2>
+
+ <p>Each section of Profiler data can be enabled or disabled by setting a corresponding config variable to <var>TRUE</var> or <var>FALSE</var>. This can be done one of two ways. First, you can set application wide defaults with the <dfn>system/application/config/profiler.php</dfn> config file.</p>
+
+ <code>$config['config']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br />
+ $config['queries']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br /></code>
+
+ <p>In your controllers, you can override the defaults and config file values by calling the <kbd>set_profiler_sections()</kbd> method of the <a href="../libraries/output.html">Output class</a>:</p>
+
+ <code>$sections = array(<br />
+ &nbsp;&nbsp;&nbsp;&nbsp;'config' &nbsp;=> TRUE,<br />
+ &nbsp;&nbsp;&nbsp;&nbsp;'queries' => TRUE<br />
+ &nbsp;&nbsp;&nbsp;&nbsp;);<br />
+ <br />
+ $this->output->set_profiler_sections($sections);</code>
