Symfony integration for Sentry.

Stable release Total Downloads Monthly Downloads License

Build Status Coverage Status Discord


Use sentry-symfony for:

  • A fast Sentry setup
  • Easy configuration in your Symfony app
  • Automatic wiring in your app. Each event has the following things added automatically to it:
    • user
    • Symfony environment
    • app path
    • excluded paths (cache and vendor)

Installation with Symfony Flex (Symfony 4 or newer):

If you're using the Symfony Flex Composer plugin, you can install this bundle in a single, easy step:

composer require sentry/sentry-symfony

This could show a message similar to this:

   The recipe for this package comes from the "contrib" repository, which is open to community contributions.
    Review the recipe at

    Do you want to execute this recipe?

Press y and return to allow the installation.

Installation without Symfony Flex:

Step 1: Download the Bundle

You can install this bundle using Composer:

composer require sentry/sentry-symfony:^3.0

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

// app/AppKernel.php

// ...
class AppKernel extends Kernel
    public function registerBundles()
        $bundles = [
            // ...
            new \Sentry\SentryBundle\SentryBundle(),

        // ...

    // ...

Note that, unlike before in version 3, the bundle will be enabled in all environments; event reporting, instead, is enabled only when providing a DSN (see the next step).

Configuration of the SDK

Add your Sentry DSN value of your project, if you have Symfony 3.4 add it to app/config/config_prod.yml for Symfony 4 or newer add the value to config/packages/sentry.yaml. Keep in mind that leaving the dsn value empty (or undeclared) in other environments will effectively disable Sentry reporting.

    dsn: ""
        enabled: true # flushes Sentry messages at the end of each message handling
        capture_soft_fails: true # captures exceptions marked for retry too
        environment: '%kernel.environment%'
        release: '%env(VERSION)%' #your app version
        excluded_exceptions: #exclude validation errors
            - App\Exception\UserNotFoundException
            - Symfony\Component\Security\Core\Exception\AccessDeniedException

The parameter options allows to fine-tune exceptions. To discover more options, please refer to the Unified APIs options and the PHP specific ones.

Optional: use monolog handler provided by sentry/sentry (available since 3.2.0)

Note: this step is optional

If you're using monolog for logging e.g. in-app errors, you can use this handler in order for them to show up in Sentry.

First, enable & configure the Sentry\Monolog\Handler; you'll also need to disable the Sentry\SentryBundle\EventListener\ErrorListener to avoid having duplicate events in Sentry:

    register_error_listener: false # Disables the ErrorListener
            enabled: true
            level: error

Then enable it in monolog config:

            type: service
            id: Sentry\Monolog\Handler

Additionally, you can register the PsrLogMessageProcessor to resolve PSR-3 placeholders in reported messages:

        tags: { name: monolog.processor, handler: sentry }

Optional: use custom HTTP factory/transport

Since SDK 2.0 uses HTTPlug to remain transport-agnostic, you need to have installed two packages that provides php-http/async-client-implementation and http-message-implementation.

This bundle depends on sentry/sdk, which is a metapackage that already solves this need, requiring our suggested HTTP packages: the Curl client and Guzzle's message factories.

If instead you want to use a different HTTP client or message factory, you can override the sentry/sdk package adding the following to your composer.json after the require section:

    "replace": {
        "sentry/sdk": "*"

This will prevent the installation of sentry/sdk package and will allow you to install through Composer the HTTP client or message factory of your choice.

For example for using Guzzle's components:

composer require php-http/guzzle6-adapter guzzlehttp/psr7

A possible alternate solution is using pugx/sentry-sdk, a metapackage that replaces sentry/sdk and uses symfony/http-client instead of guzzlehttp/guzzle:

composer require pugx/sentry-sdk

Maintained versions

  • 3.x is actively maintained and developed on the master branch, and uses Sentry SDK 2.0;
  • 2.x is supported only for fixes; from this version onwards it requires Symfony 3+ and PHP 7.1+;
  • 1.x is no longer maintained; you can use it for Symfony < 2.8 and PHP 5.6/7.0;
  • 0.8.x is no longer maintained.

Upgrading to 3.0

The 3.0 version of the bundle uses the newest version (2.x) of the underlying Sentry SDK. If you need to migrate from previous versions, please check the document.


The Sentry 2.0 SDK uses the Unified API, hence it uses the concept of Scopes to hold information about the current state of the app, and attach it to any event that is reported. This bundle has three listeners (RequestListener, SubRequestListener and ConsoleListener) that adds some easy default information. Since 3.5, a fourth listener has been added to handle the case of Messenger Workers: MessengerListener.

Those listeners normally are executed with a priority of 1 to allow easier customization with custom listener, that by default run with a lower priority of 0.

Those listeners are final so not extendable, but you can look at those to know how to add more information to the current Scope and enrich you Sentry events.

Services configuration

Services registered by the bundle (the ClientBuilder in the example below) can be configured in several ways, one of them is by using a compiler pass:

final class SentryCustomizationCompilerPass implements CompilerPassInterface
    public function process(ContainerBuilder $containerBuilder): void
        // Example - setting own serializer to Sentry\ClientBuilder
            ->addMethodCall('setSerializer', [
                new Reference(MyCustomSerializer::class),

Custom serializers

The option class_serializers can be used to send customized objects serialization.

            YourValueObject: '@ValueObjectSerializer'

Several serializers can be added and the serializable check is done using instanceof. The serializer must implements the __invoke method returning an array with the information to send to sentry (class name is always sent).

Serializer example:

final class ValueObjectSerializer
    public function __invoke(YourValueObject $vo): array
        return [
            'value' => $vo->value()
