How do I disable the Symfony 2 profiler bar?

Question

It\'s not adding anything and it makes the page slower and I want it gone. Don\'t ask. There\'s little about the profiler on the website and nothing in the app config.

Answer 1

To still get output in /_profiler but without the toolbar, you can cheat:

$request->headers->add(array('X-Requested-With' => 'XMLHttpRequest'));

That's because in WebProfilerBundle/EventListener/WebDebugToolbarListener.php there's an explicit check for this before injecting the toolbar.

Answer 2

Additional: if you want to disable it for a special action in your controller than use this:

if ($this->container->has('profiler'))
{
    $this->container->get('profiler')->disable();
}

Answer 3

If you are worried about performance - then you should not be running under dev. Dev also limits caching and can pull in additional bundles.

Run in prod mode and warm your cache before you run performance tests.

Answer 4

Try this

framework:
    profiler: { only_exceptions: true }

in your app/config/config_dev.yml

Answer 5

This setting is in app/config/config_dev.yml:

web_profiler:
    toolbar: true
    intercept_redirects: false

Answer 6

If you set framework.profiler.collect to false in your config.yml, the profiler bar won't be shown (even if web_profiler.toolbar is set to true).

 framework:
    profiler:
        collect: false

This then allows you to selectively activate collectors in your code manually, like this:

$this->container->get('profiler')->enable();
