CodeIgniter Application Profiling - CodeIgniter

What is CodeIgniter Application Profiling?

When constructing a web utility, we are very much concerned about the overall performance of the website in terms of how much time the controller took to execute and what kind of memory is used. Not only the overall performance, but we also need to see the insights of information like post data, facts of database queries, session data and many others. For restoring purpose while developing some application. CodeIgniter has made this task simpler for us by means of profiling and software.

How to Enable Profiling?

To enable profiling of your application, simply execute the command given below in any of the method of your controller.

$this->output->enable_profiler(TRUE);

The report of the profiling can be seen at the bottom of the page after enabling it.

How to Disable Profiling?

To disable profiling of your application, simply execute the command given below in any of the method of your controller.

$this->output->enable_profiler(FALSE);

Enable / Disable Profiler section

Profiling can be performed by a section basis. you may enable or disable profiling of a segment by using setting a Boolean value true or false. in case you want to set profiling on the application then you can do a record located in software/config/profiler.php
as an example, the subsequent command will allow profiling queries for the whole application.

$config['queries'] = TRUE;

In the following table, the key is the parameter, which can be set in the config array to enable or disable a particular profile.

The profiler set in the file in application/config/profiler.php can be overridden by using the set_profiler_sections() function in controllers as shown below.

$sections = array( 'config' => TRUE, 'queries' => TRUE ); $this->output->set_profiler_sections($sections);
