How do I disable the Symfony 2 profiler bar? - debugging

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

This setting is in app/config/config_dev.yml:
web_profiler:
toolbar: true
intercept_redirects: false

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 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();
Documentation here: http://symfony.com/doc/current/reference/configuration/framework.html#collect

Answer 4

If you have created a new Symfony project since Symfony 2.5, these parameters are set in app/config/paramaters.yml
parameters:
# ...
debug_toolbar: true
debug_redirects: false
Just set debug_toolbar to false.

Answer 5

Symfony 5.3.7
I changed the toolbar value to false in the web_profiler.yaml and the toolbar was disabled.
{# [root_directory]/config/packages/dev/web_profiler.yaml #}
web_profiler:
toolbar: true --> Change to false
intercept_redirects: false

Answer 6

Try this
framework:
profiler: { only_exceptions: true }
in your app/config/config_dev.yml

Answer 7

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 8

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 9

Another way that seems to disable it, is to not have _dev in the routing of the application.
So for me in a bitnami install of Symfony 2, simply by changing app/conf/httpd-app.conf slightly it would change the program:
RewriteBase /symfony/app_dev.php
to
RewriteBase /symfony/
and it would keep the toolbar from coming up.
