<h1>Profiling Your Application</h1>

<p>The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages.
This information can be useful during development in order to help with debugging and optimization.</p>


<h2>Initializing the Class</h2>

<p class="important"><strong>Important:</strong>&nbsp; This class does <kbd>NOT</kbd> need to be initialized. It is loaded automatically by the
<a href="../libraries/output.html">Output Class</a> if profiling is enabled as shown below.</p>

<h2>Enabling the Profiler</h2>

<p>To enable the profiler place the following function anywhere within your <a href="controllers.html">Controller</a> functions:</p>
<code>$this->output->enable_profiler(TRUE);</code>

<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>

<p>To disable the profiler you will use:</p>
<code>$this->output->enable_profiler(FALSE);</code>

<h2>Setting Benchmark Points</h2>

<p>In order for the Profiler to compile and display your benchmark data you must name your mark points using specific syntax.

Please read the information on setting Benchmark points in <a href="../libraries/benchmark.html">Benchmark Class</a> page.</p>
