Profiling Your Application
+ +The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages. +This information can be useful during development in order to help with debugging and optimization.
+ + +Initializing the Class
+ +Important: This class does NOT need to be initialized. It is loaded automatically by the +Output Class if profiling is enabled as shown below.
+ +Enabling the Profiler
+ +To enable the profiler place the following function anywhere within your Controller functions:
+$this->output->enable_profiler(TRUE);
+
+ When enabled a report will be generated and inserted at the bottom of your pages.
+ +To disable the profiler you will use:
+$this->output->enable_profiler(FALSE);
+
+
+Setting Benchmark Points
+ +In order for the Profiler to compile and display your benchmark data you must name your mark points using specific syntax.
+ +Please read the information on setting Benchmark points in Benchmark Class page.
+ + +Enabling and Disabling Profiler Sections
+ +Each section of Profiler data can be enabled or disabled by setting a corresponding config variable to TRUE or FALSE. This can be done one of two ways. First, you can set application wide defaults with the application/config/profiler.php config file.
+ +$config['config'] = FALSE;
+ $config['queries'] = FALSE;
+
+ In your controllers, you can override the defaults and config file values by calling the set_profiler_sections() method of the Output class:
+ +$sections = array(
+ 'config' => TRUE,
+ 'queries' => TRUE
+ );
+
+ $this->output->set_profiler_sections($sections);
+
+ Available sections and the array key used to access them are described in the table below.
+ +| Key | +Description | +Default | +
