How to Access Profiling Data Programmatically

Most of the times, the profiler information is accessed and analyzed using its web-based visualizer. However, you can also retrieve profiling information programmatically thanks to the methods provided by the profiler service.

When the response object is available, use the loadProfileFromResponse() method to access to its associated profile:

1
2

// ... $profiler is the 'profiler' service
$profile = $profiler->loadProfileFromResponse($response);

When the profiler stores data about a request, it also associates a token with it; this token is available in the X-Debug-Token HTTP header of the response. Using this token, you can access the profile of any past response thanks to the loadProfile() method:

1
2

$token = $response->headers->get('X-Debug-Token');
$profile = $container->get('profiler')->loadProfile($token);

The profiler service also provides the find() method to look for tokens based on some criteria:

1
2
3
4
5
6
7
8
9
10
11
12

// get the latest 10 tokens
$tokens = $container->get('profiler')->find('', '', 10, '', '', '');

// get the latest 10 tokens for all URL containing /admin/
$tokens = $container->get('profiler')->find('', '/admin/', 10, '', '', '');

// get the latest 10 tokens for local POST requests
$tokens = $container->get('profiler')->find('127.0.0.1', '', 10, 'POST', '', '');

// get the latest 10 tokens for requests that happened between 2 and 4 days ago
$tokens = $container->get('profiler')
    ->find('', '', 10, '', '4 days ago', '2 days ago');
