<h1>Profiling Your Application</h1>
60
 
 
61
 
<p>The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages.
62
 
This information can be useful during development in order to help with debugging and optimization.</p>
63
 
 
64
 
 
65
 
<h2>Initializing the Class</h2>
66
 
 
67
 
<p class="important"><strong>Important:</strong>&nbsp; This class does <kbd>NOT</kbd> need to be initialized. It is loaded automatically by the
68
 
<a href="../libraries/output.html">Output Class</a> if profiling is enabled as shown below.</p>
69
 
 
70
 
<h2>Enabling the Profiler</h2>
71
 
 
72
 
        <p>To enable the profiler place the following function anywhere within your <a href="controllers.html">Controller</a> functions:</p>
73
 
        <code>$this->output->enable_profiler(TRUE);</code>
74
 
 
75
 
        <p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
76
 
 
77
 
        <p>To disable the profiler you will use:</p>
78
 
        <code>$this->output->enable_profiler(FALSE);</code>
79
 
 
80
 
 
81
 
<h2>Setting Benchmark Points</h2>
82
 
 
83
 
        <p>In order for the Profiler to compile and display your benchmark data you must name your mark points using specific syntax.</p>
84
 
 
85
 
        <p>Please read the information on setting Benchmark points in <a href="../libraries/benchmark.html">Benchmark Class</a> page.</p>
86
 
 
87
 
 
88
 
<h2>Enabling and Disabling Profiler Sections</h2>
89
 
 
90
 
        <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>application/config/profiler.php</dfn> config file.</p>
91
 
 
92
 
        <code>$config['config']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br />
93
 
        $config['queries']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br /></code>
94
 
 
95
 
        <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>
96
 
 
97
 
        <code>$sections = array(<br />
98
 
        &nbsp;&nbsp;&nbsp;&nbsp;'config' &nbsp;=> TRUE,<br />
99
 
        &nbsp;&nbsp;&nbsp;&nbsp;'queries' => TRUE<br />
100
 
        &nbsp;&nbsp;&nbsp;&nbsp;);<br />
101
 
        <br />
102
 
        $this->output->set_profiler_sections($sections);</code>
103
 
 
104
 
        <p>Available sections and the array key used to access them are described in the table below.</p>
